From an engineering point and thousand of miles done in an N57 data-logging, I can tell you that Swirfflaps do not increase fuel consumption and are there only for emission purposes and that is to increase EGR gas flow at lower rpm'/load and in the cruise. Remove them in conjunction with EGR removal only and you will see massive gains in MPG. Swirl flaps should not be removed while EGR is still functioning
I deletet my egr and mapped it but I didn't not remove the swirl flaps now on cold start engine will shake and vibrates do I need to remove swirl flaps and mapped them (N57 engine )
Worth mentioning my 2011 n47 d20c has separate swirl flaps between manifold and head, bmw call it a “gasket” but it contains the flaps and shaft. Easily replaced for £25-50
Yes, I'm doing the replacement now and it is basically built into the gasket. The design is much better and the software also is improved to prevent the breakage by looking at the voltage at the motor. If it detects a large voltage or current draw, then the flap is disabled. Carbon basically is preventing the flaps from opening properly. I have a garage full of black carbon. Who thought this was good for the environment needs to be bought in front of a congressional hearing! The emission standards don't take into account of the impact of actually replacing all these parts? What about the economic impact? I'm sure the average car owner would has to pay a dealership to replace the intake manifold would just toss the car out after a few emission part failures. Look at the owners manual for the diesel - in Canada - it says replace all the emission related parts at 160,000 Kms! Yes, the NOx and O2 sensors are included in the regular maintenance with the text saying the emissions will increase past this point. This is rediculous. We need a law for emission parts to last the life of the car or to be fixed by the manufacture. Watch how quickly the life will increase of the parts.
Swirl flaps don't increase the amount of air into a cylinder when closed, what the swirling air does is improve fuel and air mixing partly as a result of the angle it enters the combustion chamber (like you said) but also because of the increased air speed, which helps light throttle emissions, power and economy.
Bullshit, you just need to keep them clean. It is quite easy to remove intake manifold in M47/M57 engines, you need to remove it while replacing glow plugs, it is good opportunity to clean intake manifold and check swirl flaps condition. Done it twice. There is also an option to replace intake manifold with reinforced (brass) swirl flaps, and that's what I would suggest in older engines.
Maybe because you have removed the swirflaps butt your egr is still active..so if you drive low rpm all the time the burning is bad and if the burning is bad you will have black and bad exhaust smoke what will block your dpf so now it regenerate more! It just a theorie,I am not sure
Thought I recognised the name, thanks for the comment on my upload George. I appreciate what you're saying with this one, but it really doesn't apply to my 330D as you recommended. And with the correct coding out and remapping, the car runs 100% better than it did. The restriction of air flow over the flaps was quite unbelievable in my opinion, removing a combination of parts (EGR/Swirl Flaps/DPF(if you choose) can prevent you from having to fork out on HUGE diagnostic & repair bills.... ever again. It all depends on what you are comfortable doing at the end of the day, and I have no regrets. The car feels amazing. Keep up the good work mate.
No problem my man. Likely worth removing on the M57 engine but not the later N57 engine. You’ll notice a big increase when you remove EGR and remap yes but do that first and then remove the swirl flaps and you’ll notice the drop in low down torque and MPG overall 👍🏻
@@GeorgeAusters Its not exactly a huge loss of low down torque. and that can be compensated for in the map. The fact is George, its a matter of opinion, you lose a small amount of torque and some MPG and gain more power and A LOT of money in your pocket from not having to take it in for a costly repair. I've been in the game a while mate, I know how car manufacturers work LOL
@@JaseWilks I'm not saying don't get it remapped but you're going to lose low down torque and MPG whether it's remapped or not. Like I said.. I would probably recommend it on M47 and M57 but no need on the N47 and N57 mate
George Austers I don’t want to sound like a dick, mate.. but I beg to differ considering my flaps&housings had already started cracking (may be a one off) But that a side. From a preventative maintenance point of view. Removing them, along with the egr. Saves you from having these issues in the future. It’s a common fault on BMWs and a trip to dealership will be VERY expensive. Spending £600+ on one part + labour, on a 10 year old car seems a bit ridiculous. Especially when it’ll just happen again. Keep it up my man 👌
So you're one of these selfish people who doesn't give a shit about the environment, yeah you just remove all that,they only put it on for a laugh at the factory, fuck everyone else except for yourself.
My BMW independent mechanic mentioned a manifold leak (not sure from where but there is lot of carbon soot built up around manifold & cover). My 2008 X3 E83 N47 2.0d is showing 3 glow plugs faults, so while we are replacing Glow plug might get manifold replaced. Was going to order cheap Manifold without flaps from eBay but he advised to buy one from reputable parts supplied with flaps and actuator motor given Genuine costs $2.5k in Aus. So after having seen your video it explains why he asked me to stick to original setup. Very nice animation by the way. You X3 N47 videos have really helped me understand how my car drives. Hopefully with your helpful advice and Timing chain hanging in there, I can get from 200k km to 250k before I dump this car. Not sure if I want to touch any of injectors just yet, one of them is starting to leak very slight diesel though)
@@GeorgeAusters ordered $600 manifold with new actuator and flaps. Let's hope old glow plugs come out intact 🤞 amd and new manifold fixes the exhaust leak.
Let's also mention that these swirl flap round gates falls down from the tube and enters the engine combustion chamber, unless you're lucky enough where they get stuck right before the engine valves. When tuning my bmw at some point I had to remove the EGR and also remove these swirl flaps, So when I checked I found two swirl flap gates were already stuck and could destroy my engine at any time, luckily I removed them In the correct time.
6:41 isn’t it possible just to replace the rod and swirl flaps? Why the need to replace the inlet manifold if it’s just the rod and swirl flaps in question.
An explanation that everyone can understand. I come with an incident and a question at the same time. I took out the intake manifold, cleaned it and changed the flaps, all 4 were broken, 2 I found in the intake ports, I don't think the engine sucked them, I didn't find any pieces from the 2 flaps, I put everything back and it works without problems It is a BMW f30 engine, xd, 184 hp, 2014, n47 d20c Do you think they were chopped, ground, burned and put out on the exhaust, without affecting the engine???????
So I have a BMW 2 Series Active Tourer, B47 engine. Swirl flap arm gone. I am in two minds about doing this. I have only found one garage that does this, £400 all in. My concerns centre around whether it is good to do or not. I'm aware that if the manifold is replaced, then it can happen again down the road. Perhaps an aftermarket one will do better? I've found arguments for and against it. Does anybody have the same car and/ or engine with this problem?
I've got an N47 with the brass bar going through the intake for the swirl flaps. The end flap was badly worn: where the bar goes through, as if the flap was stuck and the bar wasn't, causing friction/wear on the plastic flap. It was so worn that it was about to fall off. Luckily we spotted this beforehand and removed the offending flap. 135k on the clock.
my car is bmw 520d f10 2011 the car has no power after 2000rmp the car doesn’t pull but it revs freely but struggling to go to 100km/h and we have checked everything like the turbo, the turbo actuator, egr, exhaust, diesel filter, dont know what is the issue and also it misfires slightly at low rpms around 1000rpm to 750rpm but if u rev it little it goes, the car has zero fault codes, no malfunction light what so far and we are suspecting the injectors may be bad but im thinking of the swirl flaps may be it is not working plz help what is this issue is it a swirl flaps?
I wonder why BMW decided to make the manifold rod out of brass? I can only assume it was for good corrosion resistance but has lower strength and elasticity than steel, I can only assume that it was for brass being easier to cast...
Great video I learned a lot from your stuff George keep it up. My personal opinion delete them swirl flaps. Yes there is a good reason for them being there but the potential damage they can do if they fail out weights the benefits. 100% delete them! I’m saying this cause The bar wore out and broke on my n47 and destroyed anything and everything to do with the cylinder that ate it. Could have saved a lot of money and still had a fully functioning car if I had deleted them earlier
I just bought a 2010 320d, so later manifold with the better design. Can I just replace the rod and flaps? The engine is on 201k! Drives nicely, surprisingly quiet and smooth.
After I lost power on my 2015 640d it was thought to stem from a heavily coated intake manifold and swirl flaps. I was advised to do a swirl flap delete. Massive loss in low end power after the removal. I’m contemplating just buying a brand new intake manifold in the hope it returns it back to normal …
Lots suggest to just do an engine remap after the delete, to be honest I think it’s just more modifications and a 50% increase in Insurance after looking at the comparisons sites too!
I've ended up here after some weird issues with my 640d. Having to start the engine twice to get out of limp mode every time without failure. Invested in an ENET cable and got a copy of ISTA+ I've got this showing "The monitoring detects two possible fault causes: - Detection of a broken lever between swirl-flap controller and swirl flaps. - Detection of excess wear of swirl flaps kinematics." Then in another place I've got the following: Actuator position: -4.75% Actuator Desired position: 5.01% EGR position: 0.00% EGR activation signal: 0.01% EGR Nominal Value: -9.99% How big of a job is it to get that inlet off? The car had the EGR done under warranty about 2 years ago.. I noticed darkside developments have inlets for £200 so tempted to give this a blast myself
This with screws falling in to engine is bit of a lame. - throttle bodies flaps are since beginning of time held by screws and usually what is done is that you "punch" in back side of your screw and there is nothing that can "unscrew" it. Screw becomes bit notched and does not come out if you do not grind it off. Oil catch can should help to minimise soot build up, and skip annoying intake manifold cleaning. On my Pierburg intake manifold screws are glued and they do not come off. I think I can only brake them.
thank you, this video changed my mind, l got an EGR delete from darkside developments, and i think im gonna get a new engine cover with new air intake, so hopefully l'll increase engine life
What were they like mate considering taking the cross country trip up in my 330d to see what they can do. I don't do a tonne of high/long milage so I'm too reconsidering this swirl flap change I can understand for motorway driving never really being at low rpm
Driving nearly 3 years now with deleted swirl flaps on my N47 123d No problems at all. And Mpg are the same. And if your car pulls on high revs bad, this is definitely problem not in swirl flaps 😁
Very informative video George However, my concern is that I currently have a 2014 facelifted 530Dthe N57 The car is one owner has been serviced regularly at BMW but since I’ve got the ownership I am planning to do the oil change every 7000 miles or so, but the thing is should I be concerned about the swirl flaps issue because the car currently has two years warranty with the dealership that I’ve got from, but I rather not have things going wrong with the engine as it’s absolutely perfect with no codes whatsoever on the scanner And ive done 7000 miles since I’ve got the car, so my question is should I be worrying about swirl flaps at this stage and I’m planning on getting the car carbon cleaned just be extra secure but is there a chance that they could still fail.. I do occasionally put the car in sports/sports+ just to other get a smile on my face, show off to mates the insane torque, sometimes do traffic light style launch, but I always do take care of it and engine it’s looked after and I’m at 60:40 Motorway:City driving ratio The car is currently at 88k (was 81k when I got it)
Thanks for your great vids. Used them to remove and clean my B57 manifold. However there is too much play in the shaft so I need a new one. Can you recommend an aftermarket brand? BMW want £900, which seems a bit pricey. Cheers.
Greetings from Spain, thanks for your contribution. I have an N57, I have problems with smoke and cold breaths when starting the car, I have changed injectors, heaters and heater unit but it is not solved. In the diagnosis the error "004DFF SWIRL-VALVE CONTROLLER POSITION CONTROL" appears, I don't know if this could be the cause. If I remove the SWIRL-VALVE, will the error appear or do I have to code? Thank you so much
@@GeorgeAusters The question then is: How much power are you sacrificing down low? I know you've mentioned that several times, but please quantify that with stats. Its seems reasonable to me that remapping could compensate for most, if not all, of that "lost" power.
@@AZG1164 remapping could compensate, but do yo have a DPF with m57? bcause without swirl flaps - it makes a lot more smokes at low rpm, and your system and dpf wont like it, it will cause more frequent dpf cleanings, maybe dpf problems in long term.. and diesels likes to run at low rpm.. as you know.. but if you dont have a DPF, then... its your choice, but I hate when I dont have low rp torque especially when.... 3000ccm...
confirm...i remove my swirl flaps on bmw 3 serie 320d ED....from 7 fuel consume in city ....now is 10....and under 2000 is so slow ....i remove them because when i clean'd my admision...2 swirl flaps were in the engine ....and they didnt get to the engine because of the carbon from the walls...i have pictures..
B37 engine on 2016 BMW 116d 3cylinder diesel engine... should these be removed? When done, car lost power at low revs (stuck at 70bhp/160Knm torque)....diagnostics fault reported on swirl flap motor
@@GeorgeAusters at 44k miles they were clogged with carbon and flaps only were removed. My question is now that its done, and motor rotating a shaft with no flaps, car still throws a 2C3200 error that seems to create an issue with lower mpg and limp mode (car sluggish) .... have you encountered this?
Does anybody know what is the position of the flaps when the engine is off? I have removed the actuator first and then I struggled a bit with the intake manifold so when I got it out the flaps might have turned. Now I'm not sure in what initial position should I put it back - the square rod allows shut or open initial setting. Another question, did anyone reset flap actuator adjustment/resetting with ista?
@@GeorgeAusters hi mate.can you please give me some advice in regards to my swirl flaps? I have a astra h mk5 cdti 1.9. Stage 1 remap Egr blanked Complete new inlet manifold Would i need to remove the swirl flaps? Thank you.
Appreciate this is an old post but I read all the horror posts on this and was about to get my 07 bmw 320d swirl flaps removed at 73k glad I didn’t. Should be safe at this mileage surely with fsh at BMW surely?
Loving your videos, very informative and well explained. I have the m47tu2d20 and has had the flaps deleted. I cant find anywhere if the actuator its self should be deleted and the wiring capped off. Would it throw up a fault??? or just best to leave in place.
Hi, I have a mk6 golf 2.0 TDi 110 bhp. It starts up fine but after a minute it idles very rough (car shakes, headlights flicker, revs drop...sounds like its going to break down) for about 5-10 mins. Once it warms up, it runs fine, drives fine and doesn't smoke. Had a engine light on, code stated it was the swirl flap motor. So got a swirl flap delete and an egr delete. Now no engine light, but the problem remains. Any advice will be greatly appreciated. Thanks, Sid.
I have just had a recall on my EGR done. Loss of power in the next week and diagnostics saying swirl flaps. Could this be linked the the EGR recall replacement at all? Cheers
Potentially.. your old EGR valve may have be stuck closed and now the new one is allowing exhaust gases through and your swirl flaps could be blocked up
you can also buy remanufactured used -> cleaned manifolds with betters rods and everything, I did this with my om642 320cdi (benz) for better fuel effiency and lowrpm torque
you learn something every day , but i still don't thing the updated manifold is "much better" better maybe , the screw never feel out of a carburettor flap why did they on bmw's swirl flap
Carburettor flaps and swirl flaps.. There is a big difference. Plastic flaps inside of plastic intake manifold with relatively hot operation conditions, egr gasses passing true and carbon built up. Nothing last forever
finally! Most of people told me to remove them but i knew bmw engineers put them for a reason and uve explained it. Thank u for the explanation George! greetings from abroad
Good luck when the shaft remained in the blocked position, and you have no power no preasure in turbo, the dpf does NOT regenerate, gets dirty, and then people from bmw shops tell you that new air intake (only oem) its 900€, plus the dpf clean 200€, turbo clean 200€, and nasty egr full of unburned diesel gets stucked. All of this or a 50€ euro deletion mode👍
Ikke enig med dig i, at bilen trækker dårligere ved lave omdrejninger. På min f01 740d xdrive 2014, er der ingen forskel på træk ved lave omdrejninger. Bare fjern dem, de er kun til for miljø krav.
George (when your back from the ring) I need your help along with fellow youtubers when it comes to N57 inlet manifolds!! My colleague was quoted £800 to replace his inlet manifold on his 2011 330d motor due to fault 24CF00 coming up relating to mass air flow. I decided to help him and remove the manifold to remove the carbon from the swirl flaps yet the fault code is still present straight after clearing it. I am convinced its the MAF sensor that's at fault but need some guidance from the gang.
Is there a hole burnt in the manifold? The EGR valves can stick open and burn a hole in them. I’ve never seen a MAF sensor actually fail but could still be at fault or it could be o2 sensor related.
You sure it's more air or do you perhaps mean better mixing of the reactants so better/even/cleaner combustion.... hence why you noticed 5mpg loss. Good stuff tho and thank you for the like :)
The rod is, btw, NEVER snapping. Nor are the new style flaps ever coming off - not happening. Rod snapping is LOL territory - you won't even be able to cut it with a bolt cutter. That isn't the point. EGR is a disaster for your engine - it drowns it in crud. Delete both.
Will agree yet i can see is allready leaking at the outlet of rod near the actuator motor. And for that reason i threw away mine since the seals are not replacable . The leak get worst Once you clean it and get codes for air charge pressure. I did not notice any low rpm change car has more boost and goes faster when reved change is all positive . Anyhow who drives diesel below 2000 and kill his DMF.
George Austers Low rpm cause excessive vibration and that is when flywhell work at most and put a strain on it as it try to minimise them plus turbo is not running at all or not in Full range . For turbo to be heatlhy is good to use it in all rev range so the geometry dont cut in one spot only. So all diesel owners give it a blast and work that turbo engine to burn dpf off.
George Austers push it sometimes to 3500rpm on all gears and i mean Once a day when worm to extend turbo life , lucky you have No dpf . Another positive change since flaps are gone it reach temp a lot quicker in winter.
people like u don't know the engine and then they dont know how it drives. mine swirls were removed and car feld dull. i had them reinstalled. I felt difference. is it safer removed? it is, but I still keep them in place
@@GeorgeAusters probably.. when i was looking for the kits on eBay some were saying it wasn't compatible, even though the spec was the same. I'll just get an EGR delete kit that i saw, i already have a spare dpf without the particle filter inside (i kept the catalytic part) and i'll remap it all at once.
No if you get your self different turbo that spools earlier than factory model. Some of them spool quite good from 1200rpm, so if you like to experiment, that is the way you should go, or just leave these flaps there. If you have tons of soot on them quickly build up you have bigger problems to sort out, than swirl flaps. Properly functioning diesel engine shall run for many many happy miles as long as combustion is not to rich, or inefficient.
Wondering if I should buy a e91 with 200k miles n47 2007 318d. With that many miles I suppose the timing chain has been changed. Do you think it's still a decent engine at that mileage?
I’m deleting my swirl flaps (M47) just order the kit then EGR and DPF Delete with full stainless straight through exhaust and a K&N replacement air filter and a stage one remap
BMW quoted me £800 for a new intake manifold and acculator! What a rip off! Why charge so much for a bit of plastic? Did BMW do a recall on the intake manifold failing?
Swirl flaps also control lower emissions and low revs. I won't take risk of leave them in regardless. I've replaced my entire inlet manifold from BMW 2014 only done 25k and its already the swirls flaps are leaking oil and looks doggy.
20 years or so when bmw put them in the e39 they said they were there to control the amount off air going in to the engine which when closed the engine would stop quicker also on tick over the engine ran much smoother Does anyone remember a tv program were they sat a full glass off water on the engine and it didn't spill with the engine
There can't be oil in the manifold unless the breather filter is blocked it will draw oil fumes in to the turbo and block up the manifold plus the EGR valve plus all the filter on the exhaust system( badly serviced)
George Austers ok so if a rod was machined and tapped I don’t see this being an issue really to be honest it was a great video by the way I have a 330d 2015 which I was going to delete the EGR and swirl flaps but as it’s been recalled and had a new EGR cooler replaced and all the other shit cleaned I didn’t see the point. Or make sure it’s cleaned regular somehow.

Hey mate lovely content i deleted my swirl flaps on n57 and mapped it to know about the delete but now the car is not responsive at all and also given me some faults for egr bieng stuck open is this fault coming becuase of the swirl flap delete? I have ordered a new inlet now as the car litterally has no power low down in the rev range? Any advice will be great love the content!
nothing to do with more air at all the reasson it swirls is it mixes the exhaust gasses with teh clean intake air so teh swirling effect causes a better mix of teh exhaust and intake to combust better but if teh egr is removed there is no need
@roberkkk1 you will find the egr is mostly open at lower rpm under low power state I can show you the egr maps in winols the egr would not open under load as would effect emp and vane position also 800c egt into the egr cooler and manifold is not a good idea so please tell me when the egr is used if not at low loads
Hi George, nice video defo learning from this. I am wondering what is the error code for cleaning or faulty flaps? I have this code: 24CE00: Hot Film air mass meter: Ratio of measured to calculated air mass too high. From your explanation, if feels like it is related to my code issues.
From an engineering point and thousand of miles done in an N57 data-logging, I can tell you that Swirfflaps do not increase fuel consumption and are there only for emission purposes and that is to increase EGR gas flow at lower rpm'/load and in the cruise.

6:41 isn’t it possible just to replace the rod and swirl flaps? Why the need to replace the inlet manifold if it’s just the rod and swirl flaps in question.
There’s no way to replace them without splitting the manifold
From what I heard, it's not only a hardware mod. You need to do a swirl flap software delete too.
They are there for low emissions same as the egr
They re just done so they pass euro 4
And for fuel to burn efficiently, hence the swirling effect, better combustion = more power
Would excessive idling on the n47 diesel engine cause more carbon buildup around the swirl flaps ?
Hi George what happens if you just take the intake manifold off and spray with cleaning liquid and just jet off, will this be very safe.??
Hi George could you show a video of how to replace the swirl flaps please
hi mate is mean to be move easily or a bit tension lmk plz
What about aftermarket intakes, are they any good ? Do you recommend them?
Good info. The flaps also cause the air speed to increase which aides mixing
just try to rotate the water in the bottle to get it out and you will see its going faster when swirling
mixing? mixing what? its a common rail direct injection diesel...mix the egr with the fresh air maybe?
An explanation that everyone can understand. I come with an incident and a question at the same time. I took out the intake manifold, cleaned it and changed the flaps, all 4 were broken, 2 I found in the intake ports, I don't think the engine sucked them, I didn't find any pieces from the 2 flaps, I put everything back and it works without problems
It is a BMW f30 engine, xd, 184 hp, 2014, n47 d20c
Do you think they were chopped, ground, burned and put out on the exhaust, without affecting the engine???????
Hard to say without looking into the cylinders
So I have a BMW 2 Series Active Tourer, B47 engine. Swirl flap arm gone.
I am in two minds about doing this.
I have only found one garage that does this, £400 all in.
My concerns centre around whether it is good to do or not. I'm aware that if the manifold is replaced, then it can happen again down the road.
Perhaps an aftermarket one will do better?
I've found arguments for and against it.
Does anybody have the same car and/ or engine with this problem?
I've got an N47 with the brass bar going through the intake for the swirl flaps. The end flap was badly worn: where the bar goes through, as if the flap was stuck and the bar wasn't, causing friction/wear on the plastic flap. It was so worn that it was about to fall off. Luckily we spotted this beforehand and removed the offending flap. 135k on the clock.
my car is bmw 520d f10 2011 the car has no power after 2000rmp the car doesn’t pull but it revs freely but struggling to go to 100km/h and we have checked everything like the turbo, the turbo actuator, egr, exhaust, diesel filter, dont know what is the issue and also it misfires slightly at low rpms around 1000rpm to 750rpm but if u rev it little it goes, the car has zero fault codes, no malfunction light what so far and we are suspecting the injectors may be bad but im thinking of the swirl flaps may be it is not working plz help what is this issue is it a swirl flaps?
I wonder why BMW decided to make the manifold rod out of brass? I can only assume it was for good corrosion resistance but has lower strength and elasticity than steel, I can only assume that it was for brass being easier to cast...
I was about to remove swarl flaps over the lock down situation. Thanks for that Grorge.
Same here man. I will however, take the manifold off and clean it.
Great video I learned a lot from your stuff George keep it up. My personal opinion delete them swirl flaps. Yes there is a good reason for them being there but the potential damage they can do if they fail out weights the benefits. 100% delete them! I’m saying this cause The bar wore out and broke on my n47 and destroyed anything and everything to do with the cylinder that ate it. Could have saved a lot of money and still had a fully functioning car if I had deleted them earlier
I just bought a 2010 320d, so later manifold with the better design. Can I just replace the rod and flaps? The engine is on 201k! Drives nicely, surprisingly quiet and smooth.
After I lost power on my 2015 640d it was thought to stem from a heavily coated intake manifold and swirl flaps. I was advised to do a swirl flap delete. Massive loss in low end power after the removal. I’m contemplating just buying a brand new intake manifold in the hope it returns it back to normal …
Yep exactly like I said in this video
@@GeorgeAusters wish I’d watched this beforehand! Oops, would a replacement genuine BMW intake solve the issue you reckon?
@@emma123461 Yes
Lots suggest to just do an engine remap after the delete, to be honest I think it’s just more modifications and a 50% increase in Insurance after looking at the comparisons sites too!
How are the older style not considered a recall by BMW??
I've ended up here after some weird issues with my 640d. Having to start the engine twice to get out of limp mode every time without failure. Invested in an ENET cable and got a copy of ISTA+ I've got this showing
"The monitoring detects two possible fault causes:
- Detection of a broken lever between swirl-flap controller and swirl flaps.
- Detection of excess wear of swirl flaps kinematics."
Then in another place I've got the following:
Actuator position: -4.75%
Actuator Desired position: 5.01%
EGR position: 0.00%
EGR activation signal: 0.01%
EGR Nominal Value: -9.99%
How big of a job is it to get that inlet off? The car had the EGR done under warranty about 2 years ago.. I noticed darkside developments have inlets for £200 so tempted to give this a blast myself
Can the M swirl flap or manifold be swapped for an N one?
What year what this off as I have a 2013 pre face lift and I’m sure the seals are different
Yes you have the N47D20C engine with replaceable swirl flaps
So what if I do a egr bypass will that affect anything I have a n57 engine do you think I xhould do a swirl flap delete on 130k let me no thanks
This with screws falling in to engine is bit of a lame. - throttle bodies flaps are since beginning of time held by screws and usually what is done is that you "punch" in back side of your screw and there is nothing that can "unscrew" it. Screw becomes bit notched and does not come out if you do not grind it off. Oil catch can should help to minimise soot build up, and skip annoying intake manifold cleaning. On my Pierburg intake manifold screws are glued and they do not come off. I think I can only brake them.
I have the m57 with removed swirl flaps. The by the seat of my pants dyno I have not noticed any gains or losses
Should you carbon clean a n57 engine?
thank you, this video changed my mind, l got an EGR delete from darkside developments, and i think im gonna get a new engine cover with new air intake, so hopefully l'll increase engine life
What were they like mate considering taking the cross country trip up in my 330d to see what they can do. I don't do a tonne of high/long milage so I'm too reconsidering this swirl flap change I can understand for motorway driving never really being at low rpm
Driving nearly 3 years now with deleted swirl flaps on my N47 123d
No problems at all.
And Mpg are the same.
And if your car pulls on high revs bad, this is definitely problem not in swirl flaps 😁
Very informative video George
However, my concern is that I currently have a 2014 facelifted 530Dthe N57 The car is one owner has been serviced regularly at BMW but since I’ve got the ownership I am planning to do the oil change every 7000 miles or so, but the thing is should I be concerned about the swirl flaps issue because the car currently has two years warranty with the dealership that I’ve got from, but I rather not have things going wrong with the engine as it’s absolutely perfect with no codes whatsoever on the scanner And ive done 7000 miles since I’ve got the car, so my question is should I be worrying about swirl flaps at this stage and I’m planning on getting the car carbon cleaned just be extra secure but is there a chance that they could still fail.. I do occasionally put the car in sports/sports+ just to other get a smile on my face, show off to mates the insane torque, sometimes do traffic light style launch, but I always do take care of it and engine it’s looked after and I’m at 60:40 Motorway:City driving ratio
The car is currently at 88k (was 81k when I got it)
I have 525d LCI 07`,and intake manifold don`t have swirfflaps.
Hey pal any chance you have a link for upgraded intake manifold for bmw f30 2012 N47
hi, how does the part called which is transfer movement from the actuator to the leaver? i have issue with that part which need replacement. thanks.
Thanks for your great vids. Used them to remove and clean my B57 manifold. However there is too much play in the shaft so I need a new one. Can you recommend an aftermarket brand? BMW want £900, which seems a bit pricey. Cheers.
At how many kms do you recommend doing the cleaning?
Greetings from Spain, thanks for your contribution. I have an N57, I have problems with smoke and cold breaths when starting the car, I have changed injectors, heaters and heater unit but it is not solved. In the diagnosis the error "004DFF SWIRL-VALVE CONTROLLER POSITION CONTROL" appears, I don't know if this could be the cause. If I remove the SWIRL-VALVE, will the error appear or do I have to code? Thank you so much
Hey! Did you manage to fix the smoke and 004DFF issue? I have the same problem and wonder how did you fix it!
I already put them out in my m57d25, so if I understand you correctly its not good to take them out in the n57 because of losing Power
You’ll lose low down power in any car you take them out of, but they are problematic on the M57 engine
@@GeorgeAusters The question then is: How much power are you sacrificing down low? I know you've mentioned that several times, but please quantify that with stats. Its seems reasonable to me that remapping could compensate for most, if not all, of that "lost" power.
@@AZG1164 remapping could compensate, but do yo have a DPF with m57? bcause without swirl flaps - it makes a lot more smokes at low rpm, and your system and dpf wont like it, it will cause more frequent dpf cleanings, maybe dpf problems in long term.. and diesels likes to run at low rpm.. as you know..
but if you dont have a DPF, then... its your choice, but I hate when I dont have low rp torque especially when.... 3000ccm...
@@blektheone17 Wrong! Diesels like high rpms...
how many miles would you say it takes for the rod to become loose ?

confirm...i remove my swirl flaps on bmw 3 serie 320d ED....from 7 fuel consume in city ....now is 10....and under 2000 is so slow ....i remove them because when i clean'd my admision...2 swirl flaps were in the engine ....and they didnt get to the engine because of the carbon from the walls...i have pictures..

Absolutely not, no need to remove on your engine
@@GeorgeAusters at 44k miles they were clogged with carbon and flaps only were removed. My question is now that its done, and motor rotating a shaft with no flaps, car still throws a 2C3200 error that seems to create an issue with lower mpg and limp mode (car sluggish) .... have you encountered this?
Hi my Swir flap always open. Strange.? No fault
When they end up breaking apart as it happened to hundreds other people, you will surelly regret to not have deleted it...
Like I said it's not the flaps that break apart, it's the rod that wears and can eventually snap.. Different to the previous M47 and M57
What do you mean by deleting them?
Does a 2011 123d have swirls
@@justintaylor7809 , mine is 2009 123D and there swirl flaps were there.
Why who doesn't want to have two odometers on his car 😂
Does anybody know what is the position of the flaps when the engine is off? I have removed the actuator first and then I struggled a bit with the intake manifold so when I got it out the flaps might have turned. Now I'm not sure in what initial position should I put it back - the square rod allows shut or open initial setting.
Another question, did anyone reset flap actuator adjustment/resetting with ista?
My 120d was lacking power until one day it blew some black smoke out and now it’s boosting nice? Any ideas what it was thx
Possibly blocked exhaust

Thank you.
Could you fit an intake manifold from a newer N57 to an M57 engine without any hassle? To get swirl flaps the safe way :)
No
Appreciate this is an old post but I read all the horror posts on this and was about to get my 07 bmw 320d swirl flaps removed at 73k glad I didn’t. Should be safe at this mileage surely with fsh at BMW surely?
I have the m57... if I remove the swirl flaps... what else must I remove/do. Will it still pass mot emissions?
egr,dpf
You cleaner intake valve?
I nave clean valve with kerosene
Loving your videos, very informative and well explained. I have the m47tu2d20 and has had the flaps deleted. I cant find anywhere if the actuator its self should be deleted and the wiring capped off. Would it throw up a fault??? or just best to leave in place.
I've just had mine removed on my m47, and noticed a massive difference in no low end power 😭🔋
Yep!
Me too
Hi, I have a mk6 golf 2.0 TDi 110 bhp. It starts up fine but after a minute it idles very rough (car shakes, headlights flicker, revs drop...sounds like its going to break down) for about 5-10 mins. Once it warms up, it runs fine, drives fine and doesn't smoke. Had a engine light on, code stated it was the swirl flap motor. So got a swirl flap delete and an egr delete. Now no engine light, but the problem remains.
Any advice will be greatly appreciated.
Thanks, Sid.
EGR, glow plugs, injectors
@mwhiteley4350 A dpf delete has been on the car, so I can eliminate that. But I will look into the glow plugs and injectors. Thank you for the advice.
should i delete swirl flaps on my bmw 118d with m47 engine ?
should i take that as a yes ?😅
What about on a M47N2?
Yes, watch my M47 swirl flap delete video
I have just had a recall on my EGR done. Loss of power in the next week and diagnostics saying swirl flaps. Could this be linked the the EGR recall replacement at all? Cheers
Potentially.. your old EGR valve may have be stuck closed and now the new one is allowing exhaust gases through and your swirl flaps could be blocked up
I just deleted the swirl flaps on my 123d n47 and lost all low down power and no boost low down
Just like I said lol
you can also buy remanufactured used -> cleaned manifolds with betters rods and everything, I did this with my om642 320cdi (benz) for better fuel effiency and lowrpm torque
Well I’m pretty sure the engineers had this system in place for a reason!
@@johnstonlee Yep!
If you remove the flaps, does it need a software removal also in case that you do not want any dtcs?
Yes

definitely check them!
you learn something every day , but i still don't thing the updated manifold is "much better" better maybe , the screw never feel out of a carburettor flap why did they on bmw's swirl flap
Carburettor flaps and swirl flaps.. There is a big difference. Plastic flaps inside of plastic intake manifold with relatively hot operation conditions, egr gasses passing true and carbon built up. Nothing last forever
@@puukkoallu333 yes i understand , but why build things so bad also unrepairable and gets better when it falls apart and terminates your engine
finally! Most of people told me to remove them but i knew bmw engineers put them for a reason and uve explained it. Thank u for the explanation George!
greetings from abroad
Glad this has helped you man. A lot of misinformed information on the internet 👍🏻
Good luck when the shaft remained in the blocked position, and you have no power no preasure in turbo, the dpf does NOT regenerate, gets dirty, and then people from bmw shops tell you that new air intake (only oem) its 900€, plus the dpf clean 200€, turbo clean 200€, and nasty egr full of unburned diesel gets stucked. All of this or a 50€ euro deletion mode👍
EGR removed 👍🏻
What years are "earlier" vs years for "later" years
2007-10 vs 2010-2016
Ikke enig med dig i, at bilen trækker dårligere ved lave omdrejninger. På min f01 740d xdrive 2014, er der ingen forskel på træk ved lave omdrejninger. Bare fjern dem, de er kun til for miljø krav.
George (when your back from the ring) I need your help along with fellow youtubers when it comes to N57 inlet manifolds!! My colleague was quoted £800 to replace his inlet manifold on his 2011 330d motor due to fault 24CF00 coming up relating to mass air flow. I decided to help him and remove the manifold to remove the carbon from the swirl flaps yet the fault code is still present straight after clearing it. I am convinced its the MAF sensor that's at fault but need some guidance from the gang.
Is there a hole burnt in the manifold? The EGR valves can stick open and burn a hole in them.
I’ve never seen a MAF sensor actually fail but could still be at fault or it could be o2 sensor related.
You sure it's more air or do you perhaps mean better mixing of the reactants so better/even/cleaner combustion.... hence why you noticed 5mpg loss. Good stuff tho and thank you for the like :)
You sound like a Mechanical Engineer to me. I was about to write the same post.
Will it be safe to just jet wash it ??
Yes
Man, what a legend you are ......
Appreciate you watching man!
what year is your car thank you.
2008
If they tend to break, disintegrate and get inside the chambers then spending 140 quid for a peace of mind is not a stupid idea.
2 well worthwhile N47 deletes - swirl flaps & EGR. Do both or neither. Ideally do both. They suck.
The rod is, btw, NEVER snapping. Nor are the new style flaps ever coming off - not happening. Rod snapping is LOL territory - you won't even be able to cut it with a bolt cutter. That isn't the point. EGR is a disaster for your engine - it drowns it in crud. Delete both.
Will agree yet i can see is allready leaking at the outlet of rod near the actuator motor. And for that reason i threw away mine since the seals are not replacable . The leak get worst Once you clean it and get codes for air charge pressure. I did not notice any low rpm change car has more boost and goes faster when reved change is all positive . Anyhow who drives diesel below 2000 and kill his DMF.
Why will driving below 2000rpm kill the DMF?
George Austers Low rpm cause excessive vibration and that is when flywhell work at most and put a strain on it as it try to minimise them plus turbo is not running at all or not in Full range . For turbo to be heatlhy is good to use it in all rev range so the geometry dont cut in one spot only. So all diesel owners give it a blast and work that turbo engine to burn dpf off.
I don't have a DPF on mine. I don't ONLY drive below 2000rpm but I need to get 50mpg so drive quite economically for normal driving
George Austers push it sometimes to 3500rpm on all gears and i mean Once a day when worm to extend turbo life , lucky you have No dpf . Another positive change since flaps are gone it reach temp a lot quicker in winter.
people like u don't know the engine and then they dont know how it drives. mine swirls were removed and car feld dull. i had them reinstalled. I felt difference. is it safer removed? it is, but I still keep them in place
Thanks for the video, i have an E82 with the N47D20C 143hp, and i was thinking about removing the swirl flaps, i will just clean the intake manifold.
Your 118D may not even have swirl flaps
@@GeorgeAusters probably.. when i was looking for the kits on eBay some were saying it wasn't compatible, even though the spec was the same. I'll just get an EGR delete kit that i saw, i already have a spare dpf without the particle filter inside (i kept the catalytic part) and i'll remap it all at once.
@@JoaoMadeiraDesign Have you seen my video for the EGR delete?
@@GeorgeAusters just went there to check it out. Thanks for the videos, it's a great help.
You can buy new set of flaps with shaft and carrier fo £48,so no need to remove it.
Mine still looks good with 105000 miles on it though.
Not on the N47D20A engine you can't!
Would an M47 520d suffer power loss or mpg loss after removing swirl flaps?
I have m47 engine. They are a different swirl flap setup there is no change with n47 engine after swirl flaps 'removed just a prevention measure
No if you get your self different turbo that spools earlier than factory model. Some of them spool quite good from 1200rpm, so if you like to experiment, that is the way you should go, or just leave these flaps there. If you have tons of soot on them quickly build up you have bigger problems to sort out, than swirl flaps. Properly functioning diesel engine shall run for many many happy miles as long as combustion is not to rich, or inefficient.
Wondering if I should buy a e91 with 200k miles n47 2007 318d. With that many miles I suppose the timing chain has been changed. Do you think it's still a decent engine at that mileage?
You can maybe get another 100k miles out of it but expect needing to replace most of the bushes etc at that mileage
Thank you, this video answers my question in the previous video 😁👍
What's my best option with an 08 plate 530d? What type of swirl flaps do I have. Can anyone help?
You have m57 engine. Remove the flaps and use blanking plates.

Hope it all goes well mate! Very common for swirl flaps to fail on M47👍🏻
George Austers I’m driving round crapping my self as well as hoping and praying they don’t fail just yet it’s done 200,000 miles 😬
Remove the intake manifold and inspect them mate!
I'm seriously considering the same thing on my 335d... Will it pass emissions after all of that is deleted and the ECU is tuned?
@@benjaminkluge7897 Are you in the UK?
BMW quoted me £800 for a new intake manifold and acculator! What a rip off! Why charge so much for a bit of plastic? Did BMW do a recall on the intake manifold failing?
Thank for the information!
Swirl flaps also control lower emissions and low revs. I won't take risk of leave them in regardless. I've replaced my entire inlet manifold from BMW 2014 only done 25k and its already the swirls flaps are leaking oil and looks doggy.
20 years or so when bmw put them in the e39 they said they were there to control the amount off air going in to the engine which when closed the engine would stop quicker also on tick over the engine ran much smoother Does anyone remember a tv program were they sat a full glass off water on the engine and it didn't spill with the engine
There can't be oil in the manifold unless the breather filter is blocked it will draw oil fumes in to the turbo and block up the manifold plus the EGR valve plus all the filter on the exhaust system( badly serviced)
So why can’t you just get a new rod made then ? I e stainless steel ?
You could in theory but it would be very difficult to try and attach all of the brackets and flaps back onto the rod
George Austers ok so if a rod was machined and tapped I don’t see this being an issue really to be honest it was a great video by the way I have a 330d 2015 which I was going to delete the EGR and swirl flaps but as it’s been recalled and had a new EGR cooler replaced and all the other shit cleaned I didn’t see the point. Or make sure it’s cleaned regular somehow.

BMW 116D 65 reg. Are the swirl flaps held on with screws or rod like the one shown in video?
They’re held in by a rod but they’re on the OUTSIDE of the manifold so can be replaced easily
@@GeorgeAusters just to confirm this is the 1.5 diesel 3 cylinder??
nothing to do with more air at all the reasson it swirls is it mixes the exhaust gasses with teh clean intake air so teh swirling effect causes a better mix of teh exhaust and intake to combust better but if teh egr is removed there is no need
@roberkkk1 you will find the egr is mostly open at lower rpm under low power state I can show you the egr maps in winols the egr would not open under load as would effect emp and vane position also 800c egt into the egr cooler and manifold is not a good idea so please tell me when the egr is used if not at low loads
@roberkkk1 so what is your point.....
Hi George, nice video defo learning from this. I am wondering what is the error code for cleaning or faulty flaps? I have this code: 24CE00: Hot Film air mass meter: Ratio of measured to calculated air mass too high. From your explanation, if feels like it is related to my code issues.
clean the airmass sensor easy peasy
