great one, keep it up, i'm sure a lot of people are grateful for your videos.
Thanks very much George, I'm an absolute Bimmer Beginner after buying my 120d M47N2 e87 2007 three weeks ago. I'm really finding your posts helpful and am getting prepped to do a swirlflap delete (as the car has done 175k) Thanks man!!
Good video George I’m thinking of doing mine which is a 320d e90 2007 but am a bit nervous of the process lol but what a great video step by step guide.
Good video! Some things to note though
-Most swirl flap blanks (atleast the ones sold around here) are a bit undersized, relying on the o-ring having to take up more slack than it should, which leads to the o-rings failing after a while, resulting in a boost leak. Some people add sealant on there, how good of an idea that is is up for debate. Unscrewing the flap itself from the shaft of the flap is another option (slightly different than what was done on the car in the video at the start, where the shafts were cut completely), that leaves oem quality seal. However warrants you leave the actuator shaft in place, so it prevents the flap shafts from coming out. Personally I opted for the more expensive blanks plus sealant after the first set of blanks failed as I mentioned. Either way you should keep an eye on whether the blanks have not become leaky after a while. That would be indicated with oil spray around the area.
-Must make sure all of the seals with metal washers are in place. The ones that go between the manifold and the M7 studs especially. You can see one is missing in the video, maybe he put it back on, or maybe it was lost. It wasn't mentioned. Either way they must all be there, otherwise as you tighten it up, it will crook over and likely not seal properly.
-You can leave the vacuum solenoid for the flaps in place, just loop it's inlet/outlet together with a bit of hose to prevent dirt getting in. That way you don't have a dangling connector and don't have to code it out to get rid of errors. Blank off the vacuum line that went to the flap valve close to the vacuum splitter. A bolt with smooth part of shaft will work. A bolt with full thread can leave a spiral path along the thread and cause a leak.
-While you have the manifold off, it would be a good idea to replace the 3mm (OEM uses 3.5x2 hose; 3mm and 3.2mm work fine) vacuum lines that go to the vacuum splitter under it. Especially if the vacuum hoses look like in the video, and even more if you have a car with vacuum actuated turbo. 5-6m of hose is enough to do all of them and it doesn't take long when you already have everything off.
Thank you !!!
Jet thanks for the additional info regarding the sealant aswell as the O ring, and on that note, do you reckon PTFE tape might work to make the blanks a bit bigger in diameter instead of Sealant, if the blanks are a bit pissy in the holes? then putting the O rings over the tape? Also, do you recommend using Bimmer Tool for diagnostics on a 120d M47N2 e87 2007??
@@markhorridge7104 I would not use PTFE tape on there, it might help a little bit, but overall this is not really it's purpose and it might aswell just tear apart.
Following up my previous comment, the 'more expensive' blanks seem to have failed since aswell. Maybe gooping them up in RTV to silly levels would improve the situation, but at this point I think aftermarket blanks are just a waste of time, as I've tried two different sets and both have failed in a fairly short term. Replacing the inlet manifold with one that had no flaps and therefore no holes to plug is the best way. That can be done on E46, not sure about 120d. Other than that I'd try using the OEM flaps just with removed flap from the shaft. The OEM swirl flap bodies seem to be of much better quality.
You can get a diagnostics cable for 15eur from the usual suspects and run INPA/NCSExpert. I use that, maybe other tools are better, maybe worse, I cannot say as I've not used them really.,
Great video again bro 👍🏼👍🏼👍🏼👍🏼
Thanks again!
Hello man , very nice videos, i wanted to check if my mechanic changed my tensioner behind the alternator. I couldnt find any video where is located until i saw yours. Good job keep going
Glad it helped man!
Great vid referring to the leads and pipes underneath do to you re connect all them aswell? Or are they irrelevant now ?
Done mine last year, and wish I could put up pic on the comments section, took a photo as one of the flaps/spindles was hanging on the edge of the intake ports, the carbon build up saved the engine, could have dropped in at any time!
Yep very common on these engines
Hi, can see its a long time since you commented this but, what was the mileage on the engine when the flaps was like this? Considering buying an E60 with some mileage so would be usefull info.
Usually 150k plus
Thanks amigo great video!!! Just done my first ever oil change today on my n57 330d BMTROUBLEYOU. Thanks to your video on the n47 everything went sweet and was very to do. Thanks again mate!!!
Great to hear!
@@GeorgeAusters my only mistake was that filter clamp tool u use. It wouldn't fit on Mine. It was a 36mm socket. So had to nip out and buy one. But well worth doing it yourself and easy job and u know its done right. Thanks again
@@bunabuna9287 I always use a big adjustable wrench work just as while. Some big plairs work just as well.
@@mart43 I was gonna do that. But was worried about it being the right torque when putting it back. Knowing my luck it'll piss out oil everywhere 😀
@@bunabuna9287 after a while you get a feeling for the torque settings.(I rarely use torque settings only on wheel nuts) But when you dont have a lot of experience better be safe than sorry.
this is a great video, very nice explaining! Good job man.
Thanks man!
excellent video how did you clean the engine ports
Hello George. I have the egr on the 150hp diesel engine off but not removed, and swirlflaps removed. what should be the connections in the vacuum lines that I should have? Thanks.
amazing video as usual!!!
Thanks man!
This is very well described and paced for learning. I know its not allowed but isn't it better to put a blanking plate for the EGR also?
Yes better for your engine!
Hi George another great video can you recommend a good brand for the kit for my m57
Were the swirl flaps also present on e46 320d MY2003 with manual gearbox? As i know on the e39 were present only with the automatic gearbox
George...Is it not true that these (efficient) flaps cause a smoother stalling of the engine while saving the dual mass wheel?
And do efficient flaps affect acceleration in the low RPM range ??? M87 2.0d M47
10mm dip stick bolt, did you find it to be one of the worst bolts to put back in on the car?
Great vids, while you got this engine could you please do the cover gasket!! There isn’t any great videos on youtube of it so it Would be a great video and would help a lot of people!!
Already done valve cover gasket: czcams.com/video/rRK-lLR7YqI/video.html
Great vid, any chance of a link for the kit?
Can you not leave the vacuum controller in place, put a screw in the hose like you did and plug in the map sensor without having to remap the ecu?
I have a bmw 330d m57, it has a stage 1 map and dpf delete, if I was to remove the flaps would I still lose power and would you recommend it
I recently had my BMW E84 N47 motor rebuilt. Now my car sometimes goes into limp mode (CC-ID-29). What are the possible reasons for that? It does not happen consistently. It happened 3 times since I got my car back from the shop. It happened once when I was accelerating from 80km/h to 90 or so. The second time it happened in pretty much the same conditions. But the third time it was idling in P gear. First two times it went away when I slowed down and pulled over. The third time the yellow check engine light stayed lit and it went away after I stopped and restarted the car.
I do not have a OBD2 scanner at the moment, that's why I'm asking this.
Any idea why it happens? :'(
Does removing these on a 335d (2011) cause the engine to go into limp mode? Or just a check engine light? I'd like to remove them but I'm not getting it tuned for another month or so
Have you done a video on the 330cd e46?
Missed a key bit of info but video was good ... you need to unclip the connectors underneath the manifold before you can pull it up out of the engine ... i was trying and the connectors wouldnt let it free .. could end up damaging connectors
is it fine to blank everything without removing actuator plug connected?
Hi there. So, the 10mm screws will gather at 10Nm and the 11mm screws will gather at 15Nm. So, it's that correct? From where you have that information? From the manual? Thanks.
What happens if you leave the vacuum part attached and not blanked off with a screw?
Hello mate on the m47 are thay 22 mm thank you the same engine as your one
Nice video!!
Thanks mate
great stuff, thnx for share
What size delete kit did you use please
Did you disconnected the battery?
there is another solution that may be cheaper or may not depending on if you can source it. if you get a 318d intake manifold those dont have swirl flaps so no need to do this but it could cost you more money to buy a used one of those im not sure.
I got question if anyone knows the answer. If i remove swirl flaps as in video done BUTT keep the original way of vacuum hose(he used a bolt into hose) will it work or i need to do the same as in video is done?
Perhaps you can help me with this. I have a 20d X3 with the M47 engine. I think the swirl flaps have been removed, but I’m not 100% sure. At low revs (1200-1800) I sometimes get some jerkiness, as if the throttle was on-off. Could this be because of the swirl flap delete?
I’d appreciate some feedback if you have it. Thank you 👍🏼
thanks!
What software do you use for delete the EGR from ECU?
Does anybody know where I can go to get injectors refurbished?
top job
What delete kit did you use?
Good job….
Hey, nice and informative video as always!
Would you recommend deleting the updated 32mm swirl flaps also? I've read that those are build stronger and I can't find information that those would fail and get sucked into a cylinder.
I'm about to delete the EGR and clean the intake manifold but I'm not sure if I should delete the 32mm swirl flaps along the way on my 2004 e46 320td.
Thanks!
Yes on the M47 I would
@@GeorgeAusters Thanks, will do then 👍
thats because youre a retard , flaps are there to create a swirl effect you lose power on low end when you delete the swirl flaps @@GeorgeAusters
Does this operation needs Ecu Tuning?
Maybe a stupid question but I assume no software is needed after doing the swirl flaps?
Good vids mate, i've been watching a few but my only criticism is that you don't explain what these parts do and the pro & cons of removing or upgrading them etc. I watched the EGR one and had to go an google why you was doing it.
Yeah I had the same issue with this vid.
Please do explain :)
does this affect drivability or mpg/power? , i remember someone saying itl affect low end torque, im gonna remove intake manifold and fit swirl flap blanks, also clean the egr. Can i just put a screw in the EGR Vac hose?, it should stop it from opening right?, Anyone please let me know :) Any help or tips are appreciated!
Top class
Awesome, what a well described and clearly shown tutorial! I would literally only add one thing, and that would only be what process you used to clean your intake manifold? does it split and come apart allowing you to easily strip the carbon off or is it more of a case of just scrub and hope you have it all cleaned out?
Other than that, it was 10/10.
Cheers James, I made a detailed video how to clean the intake manifold👍🏻
@@GeorgeAusters Sorry mate, I should have checked your Video library before commenting I guess, (new to this channel) in which case please ignore me.
Good Job Man.
🙌🏼
George; If you need to code our the swirl flaps anyway, are you planning on remapping the car?
Another question, why did you do a DPF off on your N47 and didn't do that on this one?
It has been remapped yes, video will be up soon enough, just a bit behind. This car doesn't have a DPF mate
Is there a way to find out if they were already removed by previous owners?
Hello, have you seen an increase in fuel consumption after the delete???? What is your fuel consumption in exterion in l/100KM???
I noticed the increase after the remap but not with the swirl flap delete as they were already removed
Hi...i just done my swirl flaps on my e60. I cover the vacuum pipe with a screw as you did. I noticed that my brake pedal is hard now before starting the engine , is that because i blocked the vacuum pipe ? Is the only thing that i done on vacuum pipes . Regards
You brake pedal should be hard before starting the engine
So everything should be ok. I noticed this after the job. It wasn't like that before .
does the check engine light stay on?
How can you tell if there the 22mm or 32mm blanks
I've been watching a couple of your videos. I've bought an e60 and turns out it's had a dpf delete and swirl flap delete. Would this need to be mapped out as the car refuses to run for 5 seconds.
Does need to be mapped out but that wouldn’t stop the car from running
Why it need mapt out after replacement.?
Why could be a like standart.?
Great video. Just one question, m7 bolts need to be torqued down to 15 or 50 Nm?
15
Two of the four of mine had snapped...good job I done it when I did😂
I saw the 4 small parts that turn the actual swirl metal blade being remove and discarded however I didn't see the actual metal swirl flap (the part which claimed many good engines) been take out Did I miss something or are they still in the manifold they just don't move any more
Because they'd already been removed
@@GeorgeAusters Ok
hey :) did you use the 22 mm swirl flaps kit or the 33 mm? I have the 320d e46 (m47d20 engine). thanks in advance.
I linked the kit to buy
@@GeorgeAusters can't see any links related to the kit. Can you please drop the link here for me?
how do you map it out
Hi, they are 22mm or 33mm?
Dear George. I deleted the swirl flaps from my e39 525d and I experience a little torque loss on lower rpm. Is it okay?
It’s okay if you’re fine with it. But yes that’s normal.
Just one question are the swirl flaps blanks 33mm or 22mm? The link is not in the description.
If you have m47, they are 22mm and if you have have m57, they are 33mm
any reason why darkside developments asks for chassis number? do they send info to dvla etc.
No it’s just to check it’s compatible for your car
What products/method did you use for cleaning out intake?
I have a full video coming soon!
@@GeorgeAusters Nice man im literally balls deep in my M57 now to change exhaust manifold(common fault) and to my delight flaps have been blanked lol Win Win!
Thanks a lot for this video... I have a question... Can I just remove the intake manifold and wash it, and put it back in place? will it harm the engine?
Of course you can👍🏻
Thank you very much for your reply my friend... Greetings from Serbia
What torque for screw and nuts?
Can you give a link for swirl flap delete parts ? Or any part number for them ?
Is the link not in the description?
@@GeorgeAusters no there isn't.
I have 530d 1999 , 135kw automatic, N57. This engine have flaps??
I just wondered when you would do this vid and load this up. I think that now we have it here. think of recommending my mate to buy an 120 D or 320D Pre-LCI Touring with the M47 163 hp what do you think about it mate ?
Sure why not!
@@GeorgeAusters thanks
@@GeorgeAusters been looking at a my Service intervals in my E91 today mate (speedometer and cluster) and I wondered if I could program that so that it would Show Service in 12,000 km which is like 7200 Miles, Standard is like 15.000 Miles (25.000KM!) (which is really Bad). Have You Got a Clue how to Do this. Great video
@@kjschrauber2126 You can code a different service interval using NCS Expert with NCS Dummy, selecting instrument cluster module. Need a laptop and a K+DCAN cable to do that.
And how do I map the Swirl flaps out I canna know how to do EGR and DPF how to map them out eventually but I've not seen a program with which you can map them out
You don't need to code them mate. There is no error for that.
@@adrianzzzsss thanks mate
@@adrianzzzsss are you sure?
@@margauxlowery4324 I blanked them 2 years ago and never had an issue since
@@adrianzzzsss good to know. Thanks ;-)
How did your clean it have you footage of it mate. I Let my intake manifold of my N47N Bath and some diesel for like two weeks and then I had to scrub it all away with a brush and a stick and a towel and I had work with a brush really nasty stuff what kind of creative just asking how did you do it mate because you've cleaned it up so fast it seems
I have a video coming soon doing it!
@@GeorgeAusters thanks
@@GeorgeAusters hey Mate, when you think the Video will ne online :D ?
27th January👍🏻
@@GeorgeAusters Thanks mate very cool
How'd u clean the manifold? jet wash or just brush? 😊
Jet wash
how come you replaced the silicone hose on egr straight pipe with the original one?
Because I prefer the OEM look
@@GeorgeAusters thanks for the reply. recently got a 320cd so can’t wait to follow your vids to bring it up to scratch
No problem mate, glad to help!
Another great video 👍
One question: with what product you clean/wash the material (manifold)?
My (e46, m47. Is a 320d sedan from 1999. Bough new. Now with 330.000kms) still have the egr... Last weekend I check the dirt inside, but it has less than that one on video.
Do you recomend to remove it? I also head that then it will increase on low rpm (bellow 2.000), it's true?
Best regards.
I have a video coming in a few weeks👍🏻
It was 5🎆 the new video about diesel filter.
Regarding my questions:
- what product you use to clean the manifold? (My still have the egr and is almost like that one)
- is it true that with the egr we have a bit more torque/power on low rpm? (Like 1500-1800)
Cheers
I have a video cleaning the intake manifold coming at the end of the month👍🏻
What are the blanks size for a 2006 bmw e90 320d m47?
Link for the kit in description isn't it?
@@GeorgeAusters i can't find it mate 🤣😅 idk if I'm stupid or something but in the description i only found your tools 🤣
Ive just bought a 2006, X5, e53, and trying to see if i still have swirl flaps or not, without taking manifold off !!
Ive taken a foto but cant post it here ? Where can i post it to let u see ??
Can you just put on the n57 intake instead?
No
Hi, I dropped a gasket in the engine, how can I get it out?
With a hook
Hi,what size is the swirl flaps on the 2.0d M47 engine?.It is a 2007 model.
You need to remove yours and measure them mate
22mm got the same year and engine and that's what fitted mine.
@@mddm26 Thank you
Do you think the removal of the flaps could case DPF issues? I’m having issues since doing this.
Not likely no
@@GeorgeAusters I managed to force a regen today on a long drive with a scanner and its fixed. 👍
what happens if you don't get it mapped out ?
Engine Management light will come on
I was wondering how did u go and clean it?
Do u soak it in soapy water?
I’ve watched other videos about this and u did it in step by step and ur the only one said about remapping it
Many thanks
Check my channel, just uploaded a video about how to clean👍🏻
@@GeorgeAusters cheers bud
13:40 I see one round gasket missing on the left

So I thought let's clean the injectors from my BMW 520 D M47 E60, after disconnecting the battery took the 1e out clean the nozel and put it back with a new fire ring, and so on until 4, put everything in place, and try to start,,,,,, NO GO,,, it doesn't get enough air somewhere, took the ECR hose off and could start but running as a camel on 3 legs, what did i do wrong... now I have IMPA BMW software, and it throws me with codes and one special one ,,,, swirl flaps .... before disconnected in the ECU, I think it came back after taking the battery of or something,,, I think to take the flaps out,,, but not the vacuum hose. it totally doesn't have power en consumption 30 ltr 100. went towing it to two garages (B quick and another ) they could not fix it) I have the car home again, so tomorrow I will take the vacuum hose off (close it) it doesn't have power if I turn the steering wheel it collapse. What do I do wrong >??????George
Fuck i almost ordered swirl flap delete kit for my m47 318d which doesn't have flaps in the first place thank God i double checked on a forum
👍👍👍
Around what mileage is better to do it? I have 110 000 and I have the original ones . Thanks
Did you loose some power after you deleted it?
You lose low down torque yes
@@GeorgeAusters Maybe it would make sense to replace it with the new one instead?
@@mishokorlov Yes
I'm just a little confused why would you delete the flaps and not just ultrasound clean the manifold? The flaps were designed to improve the efficiency of the engine, with the flaps the pressures in the engine work for the benefit of the intake, by removing the flaps you are making your engine consume more fuel, produce less power and increasing the soot production, which is the most common problem that leads to most diesel engines dying. I understand doing this when you have the need for more air intake (if engine is modded with bigger intercooler, turbo, injectors and or chip tune) but if your engine is stock and you're just doing maintenance, don't delete the flaps just clean the manifold and you're set, save yourself from issues down the road.
I agree, I’m not a fan of removing swirl flaps but on an old manifold it’s a must.. A new manifold is the best solution
Delete because flaps break and get inside your engine
@@eduardassuchodolskis8876 That happens only if you don't regularly maintain your intake manifold
14:30 swirl flap vacumm
how did you clean ?
mine was too dirty too
Watch my video how to clean a diesel intake manifold
@@GeorgeAusters i may use vapor thing, should clean very well
George my car won’t start now. Any ideas pal?
You have 12v and fuel?
@@GeorgeAusters Got it going eventually! I drained the battery trying to crank it and then had to jump it from the missus car and just kept cranking and it eventually fired up😊 I now have a coolant leak though but thats and easy fix. Thanks for the vid and the reply you've helped me a lot. I owe you a beer 👍
forgot to say, it feels faster now and idles better too! I might do the EGR delete soon also as cleaning it has made a huge difference. keep up the good work!
Hi I'm having the same problem I've done the same job cleaned everything I disconnected the battery from the engine bay I have an X-3 and now it won't start and I don't want to deaden in the battery I've also tried Easy start
what egr lol
Hi! Why did you removed swirl flaps? Whats the goal? Thanks
On this engine, it is a common issue that the flaps become brittle, break off and the flap will fall into the engine! Which in turn writes off the engine. Even bmw revised and removed them from this point on.
Because they can "go" in to the engine.
