- Not my usual video, but out of necessity, i had to do a repair to my car to avoid paying extortionate prices to a main BMW dealer.
I hope you find this useful if you have the same fault.

Never attempted repairing car, but managed to do this with the help of this video! Amazing, thanks for sharing your knowledge… car is now happy again 😊
Thank you!!! My 2010 535i xdrive dropped like this and now I finally have a fix for under 1000. God Bless you sir.
You are a legend - thank you so much for this, I’d been to multiple garages who would only change out the full system. I’ve done 100km since doing this and it’s back to normal - took some time to find the right level but all good now. Thanks again.
Thanks
Still working after 2 months?
Thanks for taking the time to make this video and for the clear logical steps taken to rectify the issue. Much appreciated. My F11 goes down on one side so I can now have a narrower focus on finding the fault than without your help.
Thanks Robert, I hope you get it sorted. For a so called premium brand, they are not very good are they, so many people with the same issues and no recall from BMW. I will not be buying another.
My f11 is sitting low on one side now, what did you find was the problem plz, was it an air bag or the compressor? Your experience could save me time and money 💰 Thanks in advance
Gday John, over the years of driving trucks I’ve had a few dump valves fail, pain in the ass really, you did well finding the fault and saved yourself a shit load of money, it’s amazes me that dealerships what to replace the whole unit and not prepared to have a go at fixing the problem and look after the customer, no mechanics anymore there parts replacement specialists, great job mate and thanks for sharing, cheers
Hi Matty, thanks for the comment. Totally agree, all part of the profit making arm of the business - fit unserviceable parts and then rip people off big time to just replace them. This will be my last Beemer mate, totally underwhelmed with the whole package from sales to after sales service! The customer is definitely not put first in their business model, shiny showrooms and free cheap crappy coffee might fool some, but not me. Cheers, Jon
Thanks Jon, your video resolved my issue. Also thank you for linking to the part you bought, resolved within 24 hours of fault occurring due to this video.
Enjoyed the video this morning. Excellent fault diagnosis Jon. I too have been working on the air suspension this weekend on my Range Rover when it dropped to its bump stops. Mine was a worn compressor piston seal. It has a very similar system to yours with compressor, valve block height sensors etc except air on all 4 corners. The air drier on mine is a replaceable part as you point out, water in the system is the main cause of problems. Keep up the good work Jon and hopefully we will see your shaper making chips soon.
Hi Gary, thanks for the comment and feedback. I can see the benefits on a 4x4, but not on a motorway cruiser. Totally unnecessary in my opinion, its just a cash cow for them. On borrowed time with me, going back to a sensible car soon. Cheers, Jon
Epic video, car went down during the day parked down. Did the nursery run with it on bump stops in town, rode like a horse cart. Came home, watched your video, ordered the solenoid on Amazon for £20. Next day I removed the compressor and the solenoid in 15 minutes, the delivery arrived that exact time, I put it together in another 15 minutes. Suspension sorted. Thanks!
Ay up Jon, nice fix! I am so pleased you were able to get a part to fix the problem. So many times these days you hear that you cant get part of a unit and the whole thing has to be purchased.
Take care mate, Tony
Hi Tony, thanks for the comment. Yeah, it's a racket. You can't get an OEM spare (I wonder why?). This will be my last ever Beemer, completely underwhelming all things considered. My last 15 years have been Skoda prior to this car, OK, a bit more basic and horrible plastic finish etc, but totally reliable and good value! They go up hills in mild frost as well, unlike this thing! Cheers, Jon
@@jonsworkshop Hi Jon, I have had 4 Skodas over the years prior to my little suzuki that I have now. Loved them all, very solid cheap reliable motoring. 😃 Tony
Very helpful video - thanks. I completed the replacement in about 2h - a bit fiddly getting the cover off (plastic nuts that can strip easily) and the sponge soundproofing had gotten wet and dirty so needed to be cleaned and dried. The car, an F11 2013 has already had a 2 new airbags and an OEM compressor about 5 yrs ago - but yesterday the rear suspension dropped on to both bump stops whilst out on the road so I knew it wasn't the air bags leaking. Also the compressor was still running which is an obvious indicator it was the input solenoid. As I was under time pressure I simply undid the input pipe, solenoid connector and the 2 screws holding the air drier tank to the main body. I then swapped out the solenoid. Thus, there is no need to remove the whole compressor unit which makes it easier and less likely to break something else. So all fixed for £23 and 2 hours work. Changing out the whole compressor (had it not been running) would not have been much harder - you can buy reconditioned original for £160 on ebay plus £80 deposit on your old unit. So even then the job would have cost £160 not the £2000 plus a stealership would have wanted (or the £1000 a specialist charged me last time).. Thanks again for your video.
Thank you, having the same symptoms on my x5 F15 with exactly the same compressor. Difference with mine was that the desiccant beads were soaking wet and had to be replaced. Your video is very helpful
Hii, I didn’t quite understand what the problem is I have the same car and the same compressor and I’ve been to multiple garages and they didn’t know the issue what is exactly the issue didn’t get it could you please tell mee
Very good video Jon, great diagnosis and fault finding. I like doing things like that. All the more satisfying when you can save yourself "a chunk of change". I enjoyed watching.
Hi Carl, thanks for the comment and feedback. Hope it endures! This will be my last Beemer, not impressed with the whole package from crappy and damn expensive run flat tyres that pull the car all over the road to not being able to make it up a 10 degree incline in mild frost, to over engineered and expensive suspension...... the list goes on! The old 80's 3 series were a much better car in my opinion, they have lost their way! Cheers, Jon
@@jonsworkshop Ok so then what kind of car/SUV would you get instead? What else has such a powerful drive, is as nice looking, as luxurious & fancy inside & out & has such cool features like seats that heat & cool? Big ass sunroof? Shiny wood trim? Awesome 4-wheel drive?
I like the safe feeling from a heavy weight mid-size SUV that can carry stuff/furniture & go over bumps & pretty deep puddles & pull stuff like Jet skis or trailers, a truck big, thick & strong enough so I don't feel I'll be smushed in a car crash... X5 is all that.
The only other SUV i've ever known that comes close to my newish to me , purchased Feb 2021 like 2 weeks before Covid lockdowns here in Miami FL, 2011 X5 is a jeep grand Cherokee limited (think it was 1996 or 97)
It was my fist SUV, i loved it so much!
BTW Thank you making this video, I learned sooooooo much! It was awesome at the end when it worked & you saved THOUSANDS!!
Of course I couldn't actually DO what you did, but i can supervise someone who can! lol
I love knowing what's wrong before complaining to a mechanic.
Proper winter tyres (not all season) solve the traction problem but expensive to maintain a second set. @@jonsworkshop
Thanks man. I'm watching u from 🇩🇪 and just ordered both of the valves. Hopefully they gone work.
Hi Jon, that's why they're called "the main stealer"! Great video as usual.
Hi Olly, thanks for the comment and support, much appreciated. Cheers, Jon
BMW 530d XDrive 2018 G31,
Hi I’ve just this second finished replacing the very same part on my car, couldn’t find anything for the G31 but it was the exact same principle.
Big thank you 🙏
This is exactly the symptoms I have on my 5 series estate which is also the same colour as yours. Many thanks, my local garage didn't want to touch it because they weren't confident that they would find the issue and I won't go anywhere near a stealer. Looking on BMW forums they all seem to be pointing at new bags even though the issue is intermittent and both sides. I'll order a new valve now. Can't thank you enough for sharing this.
Hope you get sorted, it worked for me but may not for everyone etc. Cheers, Jon
@@jonsworkshop It didn’t sort the issue out but it was useful to take the compressor out, the silica in the dryer was soaking so I dried that out. I will do a soap spray test of the whole system this weekend. I have new bags ready to go on if they are the problem. The car is approaching 80k miles so it won’t hurt to put new bags on anyway.
@@garyrobinson6247 Hey, did you solve your problem?
Hi Jon, just want to say a big thank your video, both informative and logical. I had the same issue on my F11. Having purchased the part from Amazon, installed and hey presto, working suspension at a faction of the dealer cost. again THANK YOU 👍
Glad it helped
Thank you so much for taking the time to share your knowledge. I’m looking forward to giving it a go.
Hi John, thanks for the comment and feedback, much appreciated. Cheers, Jon
nice one Jon. nice diagnosis and KISS at its best. I bet there’s loads who would disappeared down the electronic rabbit hole.
Hi Bill, nice to hear from you mate, hope you're recovered. Thanks for the comment and feedback. Cheers, Jon
@@jonsworkshop Morning Jon. Recovery going well, it’s taking me a while to get the new man feeling every one at the hospital talked about.
Lots of reasons, most of which i attributed to being totally unfit and grossly overweight pre my heart attack and bypass.
I had lost 15kg prior to attack and i’ve since lost another 5kg.
Catching covid didn’t help as did issues with medication making me bleed, sorted now so doing really well. Cardio Rehabilitation exercise classes were a shock , bloody warmup nearly killed me never mind the actual workout LOL . Even been out on the motorcycle a few times.
Thanks for the Video. Did mine this weekend.. Pretty easy job to do. Longest part of the job was drying the Desiccant out. Microwave seemed to work best.
Great job done Jon. Quick & easy. I guess some folk would just take it to the dealers & pay through the nose.
Regards.
Steve.
Hi Steve, thanks for the comment. Yep, I feel sorry for those that have, it's a complete racket. I found a Wabco complete replacement unit for about £850, pretty sure BMW won't be paying that for them. If I had ramps and all the right tooling, I could swap one of these out in about 30 mins start to finish so that's about £2600 pound an hour labour rate based on what they quoted me........ Shocking! Cheers, Jon
Superb explanation and great result with my car this evening. Thanks
Hi Jon, had the same failure on my X5 this week, took the compressor off checked the balls in the vessel and they were soaked. Took them all out put them on an old quality street tin lid and dried them using a blow torch from a distance. Put them back in reinstalled the compressor but no change. Had already ordered the solenoid valve just in case as I didn’t want the car out of action for long, that turned up in a day or so and only cost £20, swapped it this morning started it up and boom, all working perfectly.. thanks for the vid saved me a load of cash and was surprising easy to do. Happy new year fella.
@TonyWelch75, mind me asking for a link to the part you bought for the X5? Planning to do the same DIY this coming weekend but unsure of the solenoid valve to buy
@@antfraine they’ve deleted the link mate, just put the model of your car then solenoid valve for air compressor in google and loads come up. EBay do them to, I’d change the balls too whilst you have it off the car
@@antfraine put airsusfat f01 in that shopping site named after a rain Forrest
@@TonyWelch75thanks Tony. I’ve ordered one off eBay which says it’s compatible with my X5, hope it’s easy enough to do with this video and some other useful info
@@antfraine No worries, mine had dropped right down and the air spring on one side had split as a result so ended up doing them the following week. Just try to keep a jack stand under the back of the car until the springs have fully re inflated. Good luck
HI Jon thank you excellent, informative usefull helpful video 👍 I have a F11 and i might get into the same issue in the future.
Great informative Video Jon!! I learned a lot from this expose! I have a Wabco air compressor that came from my Brothers BMW powered Land Rover and wondered about various aspects of it. It works fine by the way, he took out the air bag and put coils in his Discovery as a better option. I was given the pump and turned into an air compressor for pumping up the tires on my Nissan Patrol. I put in an Ally box with a pressure tank and and made a fitting so that I could dump all the air from the tank in a split second to be able to re-seat the beads back on the rim should that happen when I was going or coming back from Beach Fishing.
I also did some homework on Wabco and found that they have or perhaps had a large Manufacturing Plant in CHINA. Makes me wonder about BMW's price justification!?
PS: A good use for one of these pumps if you can lay your hands on one for less than 2100 or 550! Just need a few tools and have a think.
John, Australia.
Hi John, thanks for the comment. Standard coil over shock would be a shed load more reliable and much cheaper to replace. If the worst comes to the worst and I have to end up replacing the whole unit, guess where the old one is going lol. Cheers, Jon
Top man I was the same this morning abit rough to work but was totally gone on way home park up and order the part
Very well done. Will help me to fix my one.
Thank you
Brilliant video John, many thenks
Hope it works for you Peter, worth a try.
Nice cheap fix Jon. The same system as was fitted to my Discovery, but it was the air bags that failed.
You can't really blame the dealer. They have to warranty the system if they repair it and they can't do that if they've delved into the pump, so they fit a new one which is warrantied. The consumer has driven this type of activity, it's just a response to what the market wants as a whole and is an expensive business. There are few garages these days that have the time and would take the risk of breaking into a component.
Best wishes, Dean.
Hi Dean, thanks for the comment, agree on the consumer bit but they are ripping people off big time. This took me about an hour to do including all the strip down etc. If I was just replacing the whole unit and using ramps etc, I could do it in about 30 mins, Wabco unit is list price at £850 so even if BMW were paying list (which they won't be), that works out about £2500 hour labour rate based on what they quoted me!! They are at it! Cheers, Jon
Thank you, mine did same, and your advice fixed it! Thank god! Perfect! Cheers Steve from Stranraer! ❤
Hi there, thanks for the helpful video! What is the best way to de pressurise the system, i think mine is going back sits on bump stops, and when sat for 3 or 4 hours is there a simple way to safely de pressurise it without the car having a fit? Cheers!!
Excellent Video.. Im just experiencing problems now.. Every morning recently Im getting in and drive off, feels like the car has no suspension. eventually the car picks the back end up and it rides fine.. I suspect my valve is on its way out.. Thanks for you Video and the link..!
Hi Jon, nice fix and well done on the diagnosis. CZcams is such a wealth of information.
Main dealers these days are such a rip off.....
Regards Kevin
Hi Kevin, thanks for the comment. You are totally right, legal robbery. Cheers, Jon
And that's why I don't go to mechanics anymore lol. Well done! 👍😊👍
Cheers!
Hi just1guy metalworks, thanks for the comment. Yup, don't blame you. Cheers, Jon
Hi, What's the betting the dealer part is a "factory" recon part and the faulty part has to be sent back for a £25 valve to fitted and a lick of paint ready for the next customer. Thanks for the interesting video. John
thank you very much!! I followed the instructions and repaired it at home) respect👌👍👍👍
Good for you, Jon! That sort of fault is much more diagnosis-friendly than a problem somewhere within an inscrutable electronic control module. Now, in your opinion, is that driver-adjustable suspension system worth having? I’ve never owned one, and it seems like a lot of potential trouble.
Hi Dudley, thanks for the comment. Short answer, No! Total waste of money, I think the whole thing is designed to draw people in dazzled by the amazing technology (and to make an absolute killing on spares by fitting un-serviceable parts as standard). I can't say I notice any real benefits. They probably have to fit it to soften out the crappy hard ride that comes from the stupid run flat tyres they put on as standard. You can probably tell I am completely underwhelmed by this car, not worth the ticket price! Cheers, Jon
Just to add, for any car it's worth having a decent OBD reader. In the case of BMWs, it's worth getting a copy of ESys & ISTA + cable which allows you read any code and reset/adjust etc. Obviously it's only worth it if you plan on keeping the car for a decent length of time.
Great video Jon - going through the same fix and waiting for the part to arrive. It's amazing and sad how few people are willing to get their hand dirty on their car or around the house.
Nice job Jon, dealerships are only there to make money and take the easy route, good diagnosis 👍👴🏻
Hi Terry, thanks for the comment, spot on mate, daylight robbery. Cheers, Jon
Good video Jon, the price doesn’t surprise me I was quoted over £900 to flush a cooling system by Skoda dealer.
Hi Chris, thanks for the comment. Yup, doesn't really matter which flavour of main dealer, they are all at it. Cheers, Jon
Hi Jon, I do rmember the compressor used to start after i have started my. Lately I did not hear anything from the compressor. Do you have any suggestion how to check?
Eyup jon
Nice bit of detective work, a miniscual price of the so called professionals cost, just like my conservartory warm roof i've just done!!!!
don't know how they sleep at night,
there's profit and extortion and everyone wants the latter in all walks of life nowadays, nobody's satisfied with just earning a honest living,
so just stepping off my soap box now!!!😬😬🤣🤣🙌🙌👍👍
By the way, was the pumping up time it;s normal rate, it took over a minute on the video
great repair job
take care
Kev
Hi Kev, thanks for the comment. Bang on mate. I think pump up was about right (guessing). The system was completely empty so I expected it to be a bit long, it's only a tiny wee compressor. On the look out now for any of these that are being chucked away, they are tiny and super quiet, perfect for the workshop! Cheers, Jon
Well done excellent video all detailed
thanks Jon
Glad you enjoyed it
Hello, I have changed the compressor but the car does not lift, do I have to lift one side? The compressor stops very quickly and does not have time to get up
Thanks Jon, very informative video. The BMW guys are probably not very keen on someone like you sharing this hack. I have the same BMW F11 and I have already replaced both spring airbags and new compressor over 2 years ago (all have failed).
Recently I’ve been getting a message on the dashboard saying “Chassis Function Restricted” and it looks like the suspension is stuck in fully up position making the ride uncomfortable above 60-70 mph.
Do you think the same discharge valve could be responsible for this scenario?
Hi, in terms of the BMW guys, I couldn't care less, if they don't want bad press, don't sell prestige brands with inherent faults they are unwilling to formally address. In terms of your error, I really wouldn't know as it is a different fault to the one I had. As the dump valve is responsible for letting excess air out the system, it could well be stuck in the closed position so for £25 it is worth a gamble. It could equally be an electrical or plc issue though. Cheers, Jon
Nice video Jon, slightly different topic to usual and saving yourself some £’s
Hi Mark, thanks for the comment and feedback, born out of necessity unfortunately. Glad it's done though. Cheers, Jon
what do you do if it pumps the air bags to the point of popping everytime after fixing this issue ?
Well done John .. Good video very informative 👍
Great Video Jon, ordered the part / replaced. Could almost pour the water out of the dessicant, but 3 minutes in the microwave all sorted. Put it all back togehre and all worked perfectly........3 days on and the 40 a fuse has blown ....any ideas what now ?( other than drop the compresor and check it all over.)
Hi Paddy, sorry, I don't have a clue with electrics and I am not a mechanic. All I can suggest is too much current being drawn therefore replace fuse, switch on and listen to see if compressor is constantly running or labouring etc. Beyond that I have no idea. Is anything shorting out where you replaced the cable blocks? Mine has not done this so I have no experience to work from either.
Thanks so much for this Jon. Just about to attempt the repair myself. I've seen some talk of having to bleed the system. Did you find that?
Hi Greg, no, mine was completely down with no pressure at all in the system. That is a good point though, just carefully undo the blue, red and feed pipes and be aware that the car will drop if you are underneath it. Cheers, Jon
@@jonsworkshop thanks a lot Jon. Took less than an hour all in. Hardest part was locating the bolts to remove the plastic housing/ under tray. I had a sporadic issue with coming out and finding the car on the bump stops. Upon removing the solenoid found a ring seal wasn’t sitting where it should. All refitted and system seemed to inflate with no need to bleed.
Garage quoted £600, repaired after watching your video for less than £25.
Thanks again.
So John I really a gallon of water spilled in
In my trunk then I started having issues now my car is dropped to the floor and I can't what do i do 5351 twin turbo all-wheel drive 2010 wagon
My f11 is sitting lower on the drivers side. Any ideas on that? Could it be an air bag or compressor? Cheers
Thx for the video, it was really usefull !
2000+bet that nearly gave you a heart attack. Nicely done as usual
Hi Steve, thanks for the comment. I said a naughty word I think lol. Cheers, Jon
Great informative video. I have the same issue. Can I just ask, how easy is it to get the unit off? Does the bumper have to come off? I’m happy doing the repair when it’s off but just wanted to check how to get the unit off. 👍🏻
Hi Adam, no the bumper stays on, there's a plastic cover to remove underneath and then 4 screws, two air hoses, and the electrics to unhook. Biggest challenge is getting the back end high enough off the ground to get underneath. As always, what worked for me may not work for you so you go in with your eyes open. Cheers, Jon
@@jonsworkshop that’s great thanks. My brother in law has some drive up ramps so I’ll use those. Cheers.
Mine was up and down - both sides - intermittently. So I had a go and found the dessicant waterlogged. Replaced the solenoid with Amazon new one also. Put back together and fitted back on. Except when I turned the ignition on.. Nothing. No sound from the compressor. just an error on the dash computer. I wired it up right I think. I'm not very electrically minded but now I'm scratching my head.
Thank you for a job and video well done.
Hi Jon great video,I'm experiencing the same issue where can I buy these valves and what are the official term for them please.
If you check the video description there is a link to where I bought mine from which hopefully still works 😀
thanks your sharing， i face the same problems in my x5 , both side drop at the same time, is possible which valve faulty ? Thanks bro.
Could be, I don't know what is in the x5 but I am sure it will be similar. Cheers, Jon
Nice one Jon. Cheers
Jon, great insight, just about to purchase a 2012 5 series tourer, 55k miles & hasn't towed, the current owner mentioned that a prospective buyer declined to purchase because the air suspension hadn't in fact been replaced, although it is working fine. What age is your BMW?
Mine was a 2017, was being the operative word. Best thing I did getting rid of it. If you want my advice, buy a Skoda Octavia estate instead. BMW have lost their way totally, getting caught up in the "how much expensive technology can we cram onto one vehicle" nonsense so they can make back the money they lose at initial sale as quickly as possible. I will never own another now. Good luck if you take the plunge, make sure you have plenty of spare cash for the upkeep if you rely on it for work.
Brilliant video John, I got back to the car this morning after leaving it for 5 hours and it had dropped on the drivers side. Started it up and it went back to normal in seconds. Do you think it's a problem with the valve you swapped out or one of the other 2 ? (the right supply)
Only had the car 3 weeks from a dealer might take it back but don't want them charging me £2100 when I'm capable of doing it my self with the help of your video.
Hi Chris, if it's only dropping on one side, it's not the £2100 compressor unit, it's either the twin valve unit or the airbag on the faulty side. The valve I changed is both sides at the same time so it's definitely not that one either. Good luck
@@jonsworkshop that's what I thought, thanks for the reply buddy.
Hi Jon! My bmw 730D 2016 has same issue one side went down. live in Glasgow. wondering if there is any way to contact you directly. Many Thanks
Hey jon! great video, i have kinda same problem on my BMW trying to find the fault, dont know if u checked but my comp makes no sound at all, did urs make a working sound even tho the valve was bad? or was it silent? thanks in advance.
Hi, it did, but with all the plastic coverings in place that conceal the unit, you can't hear it running over the engine noise. The only way to know is to remove all the coverings, you will definitely be able to hear it then if it's running. Cheers, Jon
@@jonsworkshop okay thanks! i removed the covers on mine and started engine but cant hear the comp running at all, so might think i have other issue, but i do have "power" running through all the cables to the comp! thanks for swift reply
@@TheWhizzey no bother, sounds like a siezed piston, or motor maybe on the comp unit.
I have the same issue but have changed the valve still drops but ver intermittent sometimes over night but not always I was told that compressors crack often and cause this.
Hi, definitely not a cracked compressor if it is an intermittent fault, once a compressor case is cracked, it will always be cracked and always leak. Hope this helps. Cheers, Jon
good video Jon
Hi Tr, thanks for the comment and feedback. Cheers, Jon
Great video regarding issue with bmw suspension think my bmw touring M5 is suffering from same issues was wondering were did get part for £25 would be grateful if you could help out cheers.
Hi Frank, thanks for the comment. Check out the video description, I have finally put the link in there lol. Cheers, Jon
@@jonsworkshop hi john i think i have same problem with suspension on my BMW 5 series touring M sport trying get part number for solenoid mine is 2005 / 525d any idea were get cheap replacment
My e61 drops on rear passenger side I’ve replaced both airbags still drops on passenger side about 2 inches
Well BMW 5 series quite decadent - LOL. As you might guess I did a lot of this type of work. The design of the compressor is very clean and elegant. I was curious if the two solenoids on the left are the only isolation between the compressor and the bags? Or, are there additional solenoids at the bag itself?
Those have to be the lowest height ramps ever created. Clearly you and my Scottish cousins must be a bit more trim than we Americans… LOL.
The height trimming logic can be a sneaky thing. If the height cannot be reached on one side the code writer (Hans) may command the opposing side to lower to the failing side height. This is to maintain dynamics in the error state. Inverse is true if it can’t lower properly it may force both sides to max height (snow bank logic as it thinks you have lowered to an obstruction).
Well done Jon! Hoping it behaves henceforth. 2,100 is stiff for parts. However, just wait for the carbonless generation coming up that will be an entire new level of repair cost.
Hi Dan, thanks for the comment. Lol, the ramps are leveling ramps for the motorhome, not meant to be used as I did. The car was that low I couldn't get my trolley jack under. I used the ramps to get the space for the jack and realised I could just about manage the whole job on them albeit a tight squeeze. Cheers, Jon
Great ! Thank You
Hi Jon. Great video, but wondering if you can offer any advice as my issue is slightly different. So I started to notice my near side dropping right down, the offside dropped a little, but not nearly as much, so assumed it was just being dragged down as a consequence of the NS. Anyway, I replaced both air bags at the same time, but still happening :( Was fine for the first 5 days, but the NS went completely down overnight. It pumps up really quickly again when the engine is on. Could it be one of the smaller solenoids you mentioned? Got a part number\link for those?
Been doing some further research and looks like you can change the valve block for £20, but to help diagnose, I'm going to swap the blue and red tubing over, see if the OS dops instead, then I'll know that's the faulty component.
@@TrinityCT11 hi, no idea but your investigation idea is superb. If you have changed the bags then it can only really be the twin solenoid block (or it could be a pin hole or leak in one of the lines don't forget). Please post your results here, this video is getting a lot of traffic so you may help others out. Thanks. Jon
@@TrinityCT11 Hi, I have the same problem, car drops mainly on one side. Do you have an update?
@@Asserti I replaced both airbags at the same time. Issue now resolved. Didn't have to try any further troubleshooting.
Nice one my 5Gt has started intermittently sagging on passenger side then both . But then on other days it stays up so I bet it’s the solenoid 😢
Thanks for the comment. Sounds like it, worth a try for the money. Cheers, Jon
Thanks for the video Jon. Well done for using your brain and not your wallet. Keep safe and stay well.
Hi Colin, thanks for the comment, lol, not sure which is more knackered, the brain or the wallet lol. Cheers, Jon
Wow great video
Thanks!
Hi Jon, great video and analysis . I used it to hep changing the dump solenoid on my F11 this morning. For the past 6 months I have had an intermittent fault with the car sitting down on its haunches. More obvious and immediate on the offside. Sometimes this happens within 10 minutes after switch off, sometimes it will hold pressure for a week. Once down , the car won’t rise up completely on start up on the first journey but after I stop and start the car again it does.
Anyway, changing the solenoid made no difference. I have replacement airbags on standby but based on the intermittent nature of the problem I am of the opinion they are not at fault.
What do you think? Perhaps the individual solenoids where the red/ blue pipes connect?
I am no expert so just guessing here, as it is intermittent it has to be either the double valve unit or an electrical fault, for what it costs it is worth a gamble on the valve block. If it was bags leaking it would be consistent. Let us know what you do and what results you get, many others on here with the same fault. Cheers, Jon
Hi Jon
Thanks for responding. Straight forward mechanics I can do but I was never any good at diagnosing electrical faults. With that in mind I was thinking the same thing, change the valve block. Although the double block feeds air to each bag individually I just wasn’t sure it allowed air to drain back . I can get a good one for around the £50 mark. I am currently in France, so getting one mailed over isn’t always simple but I will post on here when the job is done.
@@jonsworkshop Hi John, finally got a replacement control block which controls air to both bags and installed this last week. Unfortunately it has made no difference. No great expense, £25 for the control valve and £25 for the dump solenoid, just a pity they didn’t work. The desiccant beads did need drying out but this too hasn’t really made a difference. It is strange as the car will work as normal then perhaps 1 day in 3 the rear end lowers. This can take either 30 minutes or overnight. Once down it does not raise ( other than an initial charging up /priming of the compressor)
. After a short drive and switching off the ignition, the car returns to normal and raises up on second start up. Possibly an electrical fault or load sensor fault - who knows?
Finally cured the problem by replacing the suspension airbags. Despite the intermittent nature of the collapsing I decided to give changing the bags a go and Bingo.
@@derekscott5708 Today i changed both bags and didnt solve my problem, it made even worse, now after 1 hour my car tail is dropped, before changing it dropped after 10-14 hours. I guess i have to check my pump.
I just finished replacing the airbags on my 2012 X5 thought that would do the trick, it seems to have helped a little, in that now the suspension is not slamming when I go over a small bump, however, it is still a rough ride and the level still seems low. The thing you observed in your video is that both sides went out together, that seems to be the case on mine too, if it were one of the airbags then they would have failed separately, but both sides are low. It seems that my situation is similar would you agree?
I am a car mechanic noob, so just want to know how hard it is to get the compressor out and what part did you order? I've got a jack and jack stands, from the airbag replacement so hopefully won't need much more.
Hi Tom, I am no mechanic lol, easy to get the compressor out, a few screws and clips to remove the plastic trims etc, then 4 screws, two electrical connections and two air hoses, 20 mins tops. Based on your description it could be similar. Certainly not much to lose trying, if it doesn't work you will only have lost a few ££ and a couple of hours etc. Cheers, Jon
@@jonsworkshop thanks took it out, feeling pretty manly, hahaha. I then took apart compressor. It was full of water, black goo, brown gunk, and signs that it was quite unhealthy. I cleaned it out and dried the interior, reassembled it. Was getting ready to test it. But decided that I would just order a replacement unit aftermarket. This one has 140000 miles on it. If I get it working, I can repurpose it as a standalone compressor. After cleaning it doesn’t look too bad but worried there may be some hidden issue.
@@tomladdus9264 good luck, glad you had a go, many wouldn't!
if youre able to fix things youreself you can save a ton of money , my washing machine pump failed after 15 years , repairguy told me it would be about 150 euro's to fix and i was better off buying a new machine
took the pump out of the machine whent online to aliexpress and took a look around at the photos checking the electric points bolt mounting points and the hose hookups turns out that LG is long sumting and a chineese brand (sold here by phillips i believe) the new pump was 15 euro including shipping and the washing machine is running like new again
the newer part lacked some of the covering around the electric motor but fitted exactly like the old one did
friends fridge , same thing repair guy told him to buy new , shorted the temperature switch and the machine ran so the switch was broken , bought a new switch for 20 euro and he had a working fridge again
its allso nice to be able to say : i fixed it myself
now my kitchen tap is leaking , new tap is 140euro new cardridge to fix the leak is 8 euro ,have to take the tap a part to find out wat cardrige i need but still
Hi Watahyahknow, thanks for the comment. You are so right. And what cost to the environment of all this throw away mentality which is being driven by large industry, that never gets mentioned in the global warming debate as attacking the motorist is much easier. Sorry, ranting now. Cheers, Jon
Coo your engine sounds rough, chugs like a diesel. My Series 3 Tourer compressor was under the spare wheel, easy to get at. I had to have both gas bags replaced because they were split. No problem with my compressor at all. Regards from Australia,
Hi Dave, thanks for the comment. Makes you wonder how much of this technology is about handling, and how much is about removing weight. I am struggling to notice any appreciable difference over my old 3 Series that just had standard spring and damper setup. Great technology until it goes wrong. Cheers, Jon
Great video, i have been told i need to replace the one on my f11 - is it easy to replace the actual unit, do you have a video on this?
Hi Lee, easy to do, remove the plastic covers, 4 bolts, three electric plugs, swap the unit. No video of under the car unfortunately but there are others on YT showing this bit. Cheers, Jon
@@jonsworkshop thanks Jon. I don’t want to buy a bmw part, would you mind suggesting another option to buy , eg somewhere like euro car parts? Thanks
@@leedavis9677 hi Lee, yeah, euro car parts or GSF would be a good start. There's nothing like that near me so I have to resort to the ebay lottery.
Hi, did the both side springs gone down or one side?
The problem I m having one side of spring is more noticeable than other. Also tyre is getting scratches.
Both sides equally 👍
No guarantees, but as described in the main video, both sides down - suspect main release valve first, compressor second. One side down airbag issue or individual release valve. In my case it was the bag.
Mine is stuck all the way up… and my left side says short circuit on the diagnostic…😢
I replaced the solenoid valve and everything seemed to be good, rear end lifted up. Then I started getting same chassis faults, but rear end was up and good. With diagnostics I found out, that now my compressor can only lift rear end and not lower anymore. Do You think the new solenoid valve could be responsible for that? That the old one was stuck open and new one is stuck closed?
Hi, thanks for the comment. I have no idea as I didn't get that fault, sorry. It could be a dodgy valve maybe, if you still have the old one you could try swapping them back and see if the original fault returns. Check you haven't blocked or crimped any pipework. Apply 12v to the new valve and see if you get any movement or noise. When you apply voltage, can you blow through it etc. Can't think of anything else.
I have the same problem only on the left side, wheel is inside the weelarch but only sometimes. this week i will se what to do
Hi, if it's only one side it is a different fault, probably the air bag. Cheers, Jon
@@jonsworkshop yes, we saw that was the bag. In anycase we like your videos.
Thanks for sharing 😊
Hi I have a 530 D F11 has similar problem car sometimes (Not always) falls to rear its odd as this is sometimes , Last night parked up got in this morning car war was normal ride hight, drove down road parked for 30min had fallen to bump stops. We changed Solonoid release valve , Had it on ramp garge said its bags but cant understand why its infrequent ...
Hi, thanks for the comment. If you have changed the dump valve and it is still intermittent, go for the twin valve block next. I am not a mechanic or an expert but it definitely does not sound like bags based on your description. Cheers, Jon
My air suspension goes down periodically on the passenger side. As it is intermittent what do you think is the most likely fault - leaking solenoid?
Hi Ian, thanks for the comment. I really don't know in that situation but my guess would be, if it is intermittent then probably not the airbag itself. There is a solenoid for each side (the other unit I didn't replace on the compressor), what I don't know is if there are any more solenoids at the airbag itself, if there are then it could be that. If its electronic (system, computer, logic etc) then I am totally lost as I don't understand that stuff. Sorry not much help. Cheers, Jon
I have the exact same issue on my G31, do you know if that Solenoid will fit a 2017 G31?
Sorry, I have no idea. I am no mechanic, or even car enthusiast. Hopefully through some research you might be able to link the part number to your model.
Can the solonoid be swapped without removing the compressor from the car? I just changed my airbags and it's still dropping overnight.
Hi David, thanks for the comment and question. I would probably say no (trying to remember, but I think access is too restricted). Once you are in under the car, it's only 4 screws to drop the whole unit out so much easier to attack this on a bench would be my advice. Cheers, Jon
Does anyone know '1' how the BMW air suspension should work, mine drops down after been unused for a good few hours, the compressor kicks in when the engine is running but takes at least 5 minutes to rise to the correct height, is this normal? & '2' I got a replacement solenoid valve like recommended in the video, the rod through the middle of the new one is lose and comes out, is that normal as the rod in the old one was stuck in and took a bit of shifting, also would stick in again when put back in, is this rod meant to be stuck in or not please?
Hi Robert, I am no expert but can answer from my own experience only. 5mins sounds too long, my video was real time as a comparison, I've not checked but way less than 5 mins. Same as you exactly with the solenoid valve, the old one was tight and stuck in position, whilst the new one was loose (you can see this when I fitted it as it was dropping out etc). I have no idea how all of the above is supposed to be but can only report that a few months on I still have no issues following the replacement. Hope this helps a bit. Cheers, Jon
Hi guys. Anyone know what it means when there is moisture in the decant. I opened mine but in the video the beads were clear and it did not have the problem I have. The beads are all brown and stuck together. Any fixes guys? Thanks
Hi Bilal, I am no expert but it basically means your compressor is working too hard which probably means you have an air leak somewhere else. You can regenerate the media by pouring the beads onto a baking tray and putting in the oven at 100 C for about 45 mins. Dry the housing out with cloths and then reassemble. You also need to dry the filter papers (hair dryer should do it). Like I said, you will not have got to the root cause but this will get you going again in the meantime. Cheers, Jon
Hi Jon, Hope I can post properly this week ! Very interesting video, makes you wonder how much BMW's would cost if they took the hype out of it all. Surprised you didn't go for a new compressor though, let's face it five hundred & fifty quid and you've still saved yourself one thousand five hundred and fifty quid. Tight, that's what I reckon ! twenty-five quid Huh !
Been looking for your video for a couple of hours, until I realised, do you think I need a new solenoid or something 🤣🤣🤣🤣🤣🤣🤣🤣
Hi Del, thanks for the comment. Lol, tight and skint! Too many purchases recently, it's amazing how inventive you get when you have to, must be 20 years since I laid under a car lol. Cheers, Jon
My local mechanic changed the balloons. Didn't help so he changed the compressor ,motor with solenoid. They solved the issue. Last combined valve was not changed. My old compressor is working but pressure is inadequate. No water in air chamber, piston ring is ok and solenoid is not leaking air. What else could be wrong?
Hi Arun, I am not a mechanic (disclaimer) but based on your description, either the motor is running slow on the compressor (don't know how you could check that easily) or you have a leak somewhere. The compressor housing could have a crack in it, as could the cylinder head, or one of the joints etc. Best I can suggest is switch it on and spray leak detector all over the unit (or brush on a dilution of washing up liquid) and see if you can spot any air leaks. Failing that, real close examination of the piston ring or bore for scratches/damage, it wouldn't take much damage to lose efficiency on such a small compressor. Cheers, Jon
Hi Jon I have been having big problems with air suspension compressor unit it has been replaced but keeps blowing fuses for a few months it was perfect no problem now it's starting to blow fuses n the pump just continues to make noise and takes about 10 15 mins. What could it be?
Hi, I really am no mechanic or electrician. If you are blowing fuses it suggests the unit is drawing too much power which could be a stuck valve, trapped pipe, water ingress causing too much resistance in the cylinder and many other causes. I would suggest a full tear down to see what you can find. Cheers, Jon
Hi there where did you source the part from please.. thank you I'm following you forever if I can get this sorted... thank you
Hi Neil, check the video description, there is a link in there, hopefully it still works. Cheers,
@jonsworkshop thanks fella I appreciate you taking the time.
Something a bit different Jon and I'll bet very useful to anyone looking to fix that problem. That unit is complex. Cheers
Thanks Paul
Fantastic work Jon, the majority of the big car garages are just scammers these days. I see a £2000 tool addition for the workshop, wink wink. Tony
Hi Tony, thanks for the comment. Lol, I did consider what to spend the savings on lol, run out of room now so garage extension perhaps lol. Cheers, Jon
I would just like to ask where you got the solenoid from?
Hi Mark, I got mine off Amazon.... Check this out! amzn.eu/d/5PDcmm4
It worked for me, but may not work for you, so please consider this when purchasing. Thanks, Jon
Thanks!
Thanks very much Peter, this will go towards tooling for my workshop. Much appreciated indeed. Cheers, Jon
Hi
Do you know which value is for realise pressure and lower suspension?
It is the one I changed 👍
Great video,,,,
