What an amazing video brother! Great quality, visibility, light exposure and speech, no annoying background music, no wasting time. 10/10!
Agree with that..
Thank you for keeping all the trouble shooting so thorough and interesting I really enjoyed this video. I subscribed because you explained things so technically easy and you don’t waste my time with chatter !! 👍👍👍
I have a E61 530i and recently had vanos solenoids and inner Disa valve replaced with Febi Bilstein parts. I've also started using premium fuel. I didn't seem to have any problems before so just done for peace of mind. Since then the engine is so much smoother and sounds crisp. Also the high idle on cold start drops earlier now. I can't be sure which thing made the difference but its like having a new engine now.
Great video, George. I somehow missed this one before. I love the N52 content as my e89 has the n52. Cheers, and keep up the good work!
Nice, thanks as always Jon!
This is a great channel.
I'm finding out heaps and as usual 8,000km oil changes seem to avert most issues.
Yup oil changes are critical for the long lasting of your engine👍🏻
my new top channal i like that u stight to the point and not going off topic like most channels
Thanks man!
Good hint about the Vanos filters. Nice one George.
Welcome mate!
Another great vid mate. Your subs are gonna start going through the roof now
Haha we'll see about that!
Not if we have to watch 6 ads to get an answer
If you have a bmw car which has misfiring codes or rough idle, and you have changed the plugs and coils or even injectors but the misfiring codes still there and rough idle still persist - just do this. 1. Change your eccentric sensor with a new one, your misfire codes and rough idle will go away for good. *Remember just change/ replace your Eccentric Sensor*
My beemer has misfire 2 4 5 u think It would work for that
I love you
@@charlestutorialtv7746 did it work for you ?
@@GMBEXOTICZ did it work for you ?
My car started misfiring but no codes I'm thinking it's got to be spark plugs? What do you all think
what a great channel and great content all the time hats off to this guy love it
Cheers mate, much appreciated!
Another great video George. Thanks to you I am always cleaning vanos selenoids and filters when doing oil change. I would not beileve it could have such a impact 8-)
Thanks mate, you’re welcome as always!
@@GeorgeAusters do you have a preference on plugs and coils? I was told NGK and Delphi? You agree platinum or iridium? You are more help then you know. Cheers
Almost all what you've said actually happened to my 2008 325i. Great engine still
Thank you for this information.
Any time!
You got this man
Cheers bro!
Very very knowledgeable and clear presentation.

How can you tell if the ignition coil is bad? Is there any way to test it
Please help me! I have BMW 1.18i 2007 and its engine shakes very badly with loosing power. I have changed spark plugs and one of coil and as a last I have changed one of injector. It is better but unfortunately I still have the same issue. When I see yellow oil warning sign, engine lose the power and starts to shake and it mainly happens while driving low speed (ie. climbing an incline, reducing speed while entering a roundabout) . Do you it is because of vanos solenoids? Thank you so much for your help.
I just cleaned my MAF. Problem fixed
Just did a half pull and got a check engine light, engine started misfiring quite badly to the point where it's almost a subaru noise! I'm hoping it's a spark plug gone bad, I recently changed the oil and may have spilled a little bit so will clean that up and put new spark plugs in to see if that fixes it.
Your engine is clean
You can clean original Vanos solenoids, done mine 3 months ago, 5k miles in between, runs better than ever.
Great info. Thank you.
Glad it was helpful!
This was a great video of all the various things that people need to check when having misfires.
But id still say the most common reason for a misfire is worn spark plugs and/or coil packs...
Hey I have a bmw 328i x drive i had bought it’s making a almost diesel like dirt bike noise when I start it rpm’s are shaking 1-3 back and fourth I bought it like this when I checked the oil someone had put transmission fluid in the engine so I changed that out put the proper fluid in and put a new oil filter on I checked the spark plugs and there extremely dirty when I start it up it dies right away after I’m done revving the car I just don’t no where to start I was told it might be a solenoid or fuel pump and the car shakes to any idea?
Can you please give more content on the 130i you are running.
Enjoyed the video and obviously you had to end it with that N52 screaming 🔥🔥🔥
Yes I have some more videos coming soon👍🏻
Thanks man my car revs a lot during idle at a stop and very slow acceleration but after it picks up it’s fine but will shut off if idling too long. Also never turned on my heater or a/c the car scares me a little lol.
Very smart !!!
Hey quick question if I were to put new coils could I put the turner performance coils like that or do I need to change other things since they are going to be performance
Hi! I got a E92 bmw 2007 , 2.5i 92.000 miles on the clock..The problemI got is the engine just cut of at lower speed. I changed the VANOS solenoids the oil filter and the oil, but nothing happend, engine cuts of at lawer speeds.Can you give me some advices please! , I see you know all about this tipe of engines.Thanks allot!!!
Hey George, so I just got my E90 328i 5 months ago and put around 4.5K miles on it. Not sure if it's a weather related coincidence, but as soon as the winter weather kicked in I started running into rough/chugging experience when the car was in low rev ranges when running. I'd also get the check service engine soon message pop up on the dash and it'd eventually go away once the car stabilized upon running. Car is at 50K miles, do you think this could probably because the spark plugs have run it's course and needs a replacement?
Cheers George
No problem Graham.. Thanks as always!
Omg this was such a relief....I was throwing the 0012 code....let an idiot change my oil and noticed the code came right after ....decided to start with the filter first since it was the cheapest....found that the plastic cage thats supposed to sit inside the filter was gon....went to the dealer and had to purchase a new filter cap...it came with the cage. Installed and its back to normal again!!!
That cage is crap, just very bad engineering.
It wobbles when new, doesn't give me much confidence that it's doing perfect job of sealing properly not to let unfiltered oil through..
And sometimes gets stuck in the housing along with the filter too.
Just shit design.
That same exact situation happened to me this week after changing the vanos solenoids and changing cam sensors
Can you do a video of hwo to change that oil filter and spark plugs please ?
Very well explained videos but...you state only 3 to 4 reasons for running rough and misfires ? most common fault is vanos solenoids ? are you sure about that ? I would of thought a vacuum leak would be one of them and the most common. Vacuum hoses more much more likely to perish before vanos packs in.
Great video. All very good, rock solid pointers. That's the worst with these engines, having rough idle, can be chasing it for weeks. My Vanos solenoids have 250,000 km on them. Is it time to change you think? RPM is 600-650 at Idle causing a vibration on my tensioner pulley (recently changed).
Thanks you!
I'll be replacing mine soon!
@@GeorgeAusters if and when you make that video let us know if you feel a difference. Read some where the new vanos solenoid manufactured after 2008 are more reliable.
I having exact same problem when starts. And got worst mpg.
Ordering new maf soon. Any brand to use? My car is e60 525i lci n52 black cover.
I have a P0171...what do you think that this is?
Hello, I have an issue on my E92 325i N53 3.0L.
I have changed my High Pressure Fuel Pump, Ignition Coils, Spark Plugs and 2 Vanos Solenoids yesterday.
Also changed oil, coolant and valve cover gaskets btw.
I still have a rough idle. With the airco / AC OFF it's worse.
Any ideas what I could be, anyone?
Thanks!
you are a genius... my BMW 330i e90 cold idle goes from 600rpm to 1000rpm jumping irregularly for 30 seconds and then the idle normalizes... I don't know what it could be, I changed selenoids but the fault continues. I'll follow your advice. Thank you
Did you figure out the answer I have the same issue on my e90 except my engine will forcefully shut off after the rough idle
That engine is some clean,
Thank you my man. I did a video cleaning it👍🏻
Going to the grocery store cars running perfectly fine come back out now the car feels like it's got half the horsepower running really rough what the heck's going on any information would be highly appreciated ?
Hello good vid just got a 125i and it's got rough idle. Thanks
No prob Paul!
I have solved rpm faulty by change. Oil filter housing
If you’re burning up ignition coils you have installed the (Pre-Gapped) spark plugs with too much plug gap, you have to have the gap set to the BMW specification for the YM&M of your car. The coils will not only be unable to provide the proper quality spark, it will be shorter in duration and the coil will not be able to discharge the saturated energy, and when it maxes out, it cant cool itself, because these coils are not suspended in a heat buffering fluid, they are molded into a siliconized rubber boot, installed inside of a metal tube, with an integrated lip seal and shrouding cap at the top, trapping the heat in, and when it heats up with the engine creating more resistance in the coiled copper filament , more heat which causes a compound perpetual increase in filament temperature, that can not escape, the event spirals into a rapid self destruct sequence. I checked the “Pre Gapped “ $12.00 each iridium plugs, and they were “Pre gapped” between .068-.076” I believe the BMW specs for a 2007 328i was .036 or .040” if memory serves me, the plugs had nearly twice the amount of gap of the manufacturer’s OEM sources limit, without a coil designed to survive in high temperature severe duty conditions, that much gap will make your coils windings glow like a toaster element
Hey George, two months ago, I replaced the head gasket and all 6 spark plugs. But I'm facing intermittent misfire after that. I cleaned up the MAF sensor and oxygen sensors as well, but the issue is not resolved yet. What could be the problem?
Did you get the problem fiixd
What's up was it?.
Thanks!🫡
You’re welcome!
Hi bro good work
Great video.I have an issue with my N52 engine.l have been driving the car and all of a sudden it does not want to start it will be cranking one way.After l leave it for the whole day and l tried it and it started but it will make the raving sound and yet the rave counters will not show on the cluster until you drive then it will start showing the raves.What may be the cause of this
Could be the camshaft position sensor
Usually it's the coil pack but I have to change that nanosvalve. Because 189000
So i just did a valve cover gasket replacement and after getting it out back together, it’s running maybe a little rough, but I’m having significant power loss upon acceleration. Any tips?
Same happened to me... watch this video👍🏻
czcams.com/video/vlfTE31VlOw/video.html
@@GeorgeAusters ahhhhh okay. I replaced that seal when doing the repair however I did not remove the motor the right way, I kinda just removed the bolts then pulled it out and reverse the procedure when going back in. I wonder if that has any reason for loss of power, as I don’t really have any rough idle problems
I recently bought a bemmer and the guy sold it to me said it was misfiring after he changed the valve cover gasket and I came up with a conclusion that oil got down inside the spark plug holes I checked and sure enough oil was inside I pulled out the oil cleaned them out and the misfires disappeared
Cheers for the video, very helpful! You should do a vanos solenoid replacement tutorial?
Do you know if the N52k (128i/125i) without the three-stage manifold has any DISA valves at all??
125i has 3 stage manifold 128i does not
@@jl2929 my 325i n52b25 has 2 disa valves
I have a 2011 E91 328i with the N52. I have a misfire in cylinder 4,5,6. I changed all my spark plugs and installed Bosch coil packs. Cleaned my vanos solenoid and ended up replacing both but still misfiring after 3k RPM. Cats and o2 and checked the MAF. Car runs fine under 3k and idles fine up until I drive over 3k RPM and turn off the car and the check engine like turns off each time I turn the car on and off.
Any possibilities? I am thinking on changing the valvetronic next
Just replaced my valvetronic , could my cat be clogged or my secondary cat?
Needs scanning with ISTA
@@GeorgeAusters Thanks! I’ll try to diagnose it tomorrow, you earned my subscription!
Thanks bud👍🏻
Could you do-a review on E90 engine, having some issues with the engine periodically juddering on start up
This is the same engine in the e90

so i have a p0301, i swapped coils around and it stays on cylinder 1, my plugs are fairly new as i just did them last year, i also have a p0140 that popped up with this misfire, can no activity at bank 1 sensor 2 be related to my misfire? any help would be appreciated.

Any update on a fix to this?
Took to get my oil changed now my car has a rough idol and a high whistling noise when its in park running doesn't skip when driving runs fine just at stop signs it will skip and when idling in park
They either used the wrong oil filter or they threw away the center part of the filter.
Hi, is this an issue on s63tu engines?
I have huge rpm jumps on cold starts in the morning and after it warms up it disappears and runs normal. Cleaned Mafs sensors with no luck
did you sort it mate? i have the same problem.

Oh and btw, this is 3rd time I’m dropping car to dealer in 4 months with the same issue. During 2nd visit they replaced injectors, spark plugs, air mafs sensors, and coils. Nothing helped.
I would like to know more about the spring thing associated with the oil filter.
I guess you mean the plastic cage that goes into the filter?
Correct👍🏻

You've replaced solenoids?
@@GeorgeAusters Yes, both of them.
What if I feel vibrations on idle but idle speed are steady? I had misfire on 6 cyl but changed coil and all good now. After that i feel those vibrations stronger than before (before coil failed). I have new flywheel, clutch, changed gearbox for another reason…still feel vibrations and have hard HIT after gear change and when push/release gas pedal. Also vibrations on gas pedal when driving, when stop i feel like something moves. Wheels on the ground but car body moves forward a little. Need help with that 😞

@@menardmall217 Coils fully seated?
Will those solenoids throw a code ?
Yes, when DME detects they are not actuating the cams. TBH The solenoids rarely fail and an oil change usually fixes any issues with them.

What about rough idle just at the first start in the morning? I am thinking injectors or oil separator
Did you get help?
?? Any update?
It was one of my Disa's breaking apart

Basically anything can make it rough idle
This oil cap has to be one of the shittiest solutions in the history of the oil filtration system.
I had already a couple of times oil filter stuck in the housing after removing the cap.
Tried following the torque recommendation of 25NM, but my cap goes all the way to the end until there's thread.
Next time I find filter slightly squashed 🤦♂️
The whole rediculous basket that holds the filter is wobbly and doesn't give me confidence that it's been engineered right, as well as those hydraulic valve adjusters as BMW calls them that rattle on the start up until they get oil.
The whole system is compromised.
If your filter is crushed then it has been installed incorrectly
@@GeorgeAusters quite possibly.
Also I used K&N instead of OEM filter, but it shouldn't matter as they're the same dimensions.
Watched all the CZcams videos on installing it correctly on that ridiculous basket and after all of that, that's where I came to conclusion it's just insane what their engineers came up with.
Ok so I’m getting misfire cylinder 1-2-3-4 with fuel shut off. Random misfire. Misfire lean fuel. Misfire during start cylinder 6 -5-3 . Multiple issues. I hear the car shaking slightly and misfiring at idle. Then as soon as I start driving it has no loss of power or anything seemingly wrong. Drive on highway for an hour no issues . Parked and within a minute they come back only at idle. Your video doesn’t help with this because everything you said causes lack of power .
thanks! greatly appreciated, but why do you mispronounce all the words that have a letter "U" in them? lol
I have a 2009 750oi
Rough idle shake engine
Any suggestions?
N62 engine
2009 BMW 750i I might just be tripping about nothing. I think that's just a V8 thing
Thank you for a very useful video 👍 I also have this common idle issues on my 2006 n52 325i in direct injection.
At cold start up or when the engine been sitting for a while, the engine hunts for about 20 seconds more noticeable when in Drive or reverse gear(underload) Then it clears up and runs perfectly. Scanned for codes, no codes! Cleaned vanos changed out check valves, replaced maf sensor (genuine) no change. Should I go ahead and change out vanos solenoids even if I don't get a trouble code?
Scan with ISTA first
Did you sort out your issue, I have similar issue, no codes. I've also replaced the vanos piston seals.
@@arnolduk123 no I took the car to bmw and checked for codes, no codes.
I did take it in when it was at operating temperature which is when it doesn't have the problem.
Did you put in genuine vanos solenoids? I have been told that maybe there's a software update for the ECM by a euro car mechanic. Do you have the exact problem only on cold start? I forget to mention I did changed the magnesium valve cover gasket and the eccentric shaft sensor. Made no difference to the uneven idle on startup. I ran a injector cleaner but no difference. My car has only 98,000km change the oil and filter every year. I have never seen n the engine check light on or had any issues. I know this is a very common problem.
@@boost351 Didn't change solenoids, just cleaned up but had the full vanos stripped down and new viton o-ring seals fitted. Not much noticable difference. My issue is worse when engine gets up to temperature half way on gauge. Cold start is just a little rough for a few seconds. Exhaust sound as gradually got louder than normal also had "rotten egg" smell every now and again. Spoke to my BMW indie specialist and suspecting the cats are causing the issue, maybe restriction in exhaust. Looks like going to be expansive as I have 2 cats on my M54 engine. Not sure about an ECU update as never had any problems with the stock ECU so I can rule that out as the cause. If vanos had failed or solenoid then a code for sure would be thrown as cam timing cannot be adjusted correctly and DME will pick up on that.
Unplug both terminals on the battery and drain the remaining stored electricity by holding them together. (Idiot message: make sure the positive and negative wires are not connected to the battery). Leave your lights on and honk the horn. Let the pos/neg cables rest on each other, or run alligator clips to each other if they dont reach.
After 15 minutes the entire car should be factory reset. Connect the battery. Start it up and your idle should be adjusted. If not you have gunk in the engine. Probably the valves caked.
(Credit to some British guy I don’t know the name of).
Hey, i have misfires if i stand before a traffic signal.
I checked OBD it sayed:

George Austers the goal will keep getting higher👍
Of course🙌🏼
My diagnostic machine says misfire 2-3-4 cylinders. I replaced all plugs and two of the coils. Swapped coils to all different places. Runs a little better but still says misfire. Could it be the solenoids?
Replace all plugs and coils
@@GeorgeAusters I did That today and it didn’t help. I cleaned the mass air flow sensor too. What else could it be?
This is happening to me misfire slot 1 just doesn’t go away and my rpms aren’t staying steady. I replaced spark plug and tried multiple coils.
In my experience the connectors are shit. You flip them up to remove the wire from the coil. I found that they dont connect all the way sometimes even when all the way down. I pushed mine as far as I could and ziptied them. It fixed my issue. Misfire on cylinders 1 4 and 3
@@dongotti3618 Never thought of that, maybe the connection isn't good enough for the full spark. Suppose could try it with the engine running to see if any change in RPM. Wearing rubber gloves, obviously. I've never heard of vanos causing random misfires, yes plugs, coils and injectors, but not vanos.
The swaying back and forth is nauseating. Takes away from your great instructions.
if your engine is running rough,its most likely a because its a bmw.
Hahaha
Now I know BMW is not a reliable car after all
Wow,or... just get a lexus or toyota
ur talking to much but not showing the problem
