When the intake manifold is removed I strongly recommend to check if the oil cooler is leaking oil. Access to the oil cooler to replace the gasket and o-rings is much better with removed intake manifold.
Yep mine is fine
I really appreciate your acknowledgment George, I was inspired to do the work including the dpf internal Removel just the shell left in place from your previous videos. Keep up the well explained in detail videos for novices like me to make the cars perform better and future proof.
very thorough step by step guide. I did the job over a week, but should've taken 2 days if not for waiting for glow plugs to come in as you have access while the manifold is off. Take time to clean the cylinder heads and spoon out the carbon buildup.
Good idea with a spoon, never thought about that!
@@GeorgeAusters came out like tofee pudding
Since I have done this procedure twice once on an m47 and now on an m57 I can argue the point, swirl flap delete on its own might cause a loss in low end torque and economy but that’s by itself, but with stage 1 remap, egr deleted, and an intake manifold carbon clean it actually gives it more power, just make sure you fit the intake correctly and with all the seals otherwise you will get a boost leak and/or it could spit oil and heavy black smoke out the exhaust 😂
George. I commented on your earlier video when you discovered your problem after having done the swirl flap delete and bung insert on mine.
Your absolutely right about loss in torque and economy. Having driven the car about now, it is quite noticeable.
Your efforts and videos are much appreciated. Thanks so much keep it up.
Don't tease us with your plans for the intake. Wish I'd have known before I did the delete so I could have followed your footsteps.
i have noticed no drop im mpg and power in my 330d after the delete
Hey! Planning to buy a 335D and your videos are a treasure! Thank you for all the advice
Glad you like them!
I have also done the swirl flaps delete in my Vauxhall 1.9 CDTI as they failed and yes I could feel the lack of power low down if gear is too low car will not go anywhere as before it still had a bit of go
Very Interesting watch looking forward to doing this to my car. Thanks again bro.
Hi George, I was thinking of having a swirl flap and egr delete on my N47 2009 m sport 320 d, you have put the cat among the pigeons. I have had a price with a re map and not cheap, the car has got 47k on the clock and with a rear diff service, gear box service, is smooth. I will probably cancel the work after watching this video.
That DSD seal carrier looks interesting!
Has anyone noticed that the blanking plug does not actually touch the swirl flap mechanism housing. there is 3-4mm gap between the top of the blanking plug (with the cap fitted) and the plastic housing.
However, It does fit with the rubber swirl flap rod seal still in place. The seal with this video came out on the rod, which means the plug isn’t secured?
Is this normal? Thanks - great video by the way 👍🏻
Great video.
Do tell as to what is going into the intake manifolds space?
Coming soon!
Great video as always. You made it look so easy, you have the best chanel!
Thanks mate!
Hi George do you have a solution?
Mine where so bunged up with soot I replaced the intake manifold with brand new one deleted the swirl flaps and the egr then had it mapped got all the missing low end torque back again and knowing that it won’t choke up again. The whole design of putting the burst gases threw intake is a recipe for disaster
@George Austers - I've just watched your video on why you shouldn't remove the swirl flaps, so now I am confused!
Did you watch this whole video?
@@GeorgeAusters yes, although I may have missed a bit - if the rod is the issue is there not an upgrade for the rod?
Great video bro!!! Keep them coming
Cheers Daniel!
Great video, it helped me very much.
Thank you very much for that and greetings from Germany. 👍👍
Glad to hear man!
my e92 320d was remapped with the flaps in and since removing them i completely agree with you on the mpg loss and power its so much that i have bought a new manifold with flaps to regain the mpg and power. ill take it back for a dyno run to see what i get with them installed vs out
would be a good video to shut people up once and for all but sadly i dont make videos.
Hi mate I have had my swirl flaps removed on my e92 320d do you think if I have a stage1 remap i will feel more power as I feel it’s lost power since removing too
DO you go back to the original state with flaps? Can you share your feelings? Do you still feel the difrence?
@@337Saint it did feel more responsive at lower rmp but sadly the swirl flap actuator had a leak in the end so it was a bit lumpy on start until it got used to it just waiting on a new one
When I took the flaps off, I felt a slight vibration and a different sound from the engine. After a few months, I have a problem with less power from low torque, I wonder if the intake manifold is clogged with tar maybe? Let me know how you feel after returning the car to factory condition when you finally do it.
@@337Saint it'll clog with tar with he flaps more likely than taking them out
Excellent work 👍 😎
Thank you mate
Hi great videos , what are the symptoms of swirl flap issues
i have a 2015 335d x drive and have intermittent power lose. ?
Great content as always
Glad you enjoyed it man!
Great video, was just looking to do this!
Quick question - What is the need for the Swirl flap actuator after the delete?
To hold in the plug.
Did you code the swirl flaps delete? Because the motor won't be in the same posicion and you get propulsion error
No erors
George is spot on here... on diesel engined BMW's upon acceleration until 2250RPM the swirl flaps remain closed and open proportionally as engine speed increases, which is the exact opposite what happens on petrol engined vehicles to our logical thinking brains.
The reason for this is to speed up the velocity of air into the engine, using shaped (swirled) ports and this is why removing them will significantly worsen performance and economy.
Since when inlet restriction increase power and fuel economy?
Hi! If I did a swirl flap delete, would I need to have someone remove it from the ECU too or can I leave the ECU as is and just do it manually?
If I want to map my 320 do the flaps need to be deleted or not
Hello George if you want to not loose torque or power you must do a ecu remap now with this my e60 have 220hp and 450nm
And what is with ECU? You can‘t just pullout swirflaps from intake manifold without coding ECU (Swirlflaps off)...am I right?
@@dejanpusac5959 you can but your engine loose a bit of power and torque
You won't lose power at the top end... It's the low down torque you lose... Regardless of doing a remap or not
@@GeorgeAusters exactely George 👍
Great work 👏
Thanks ✌️
sorry mate, but I can't understand if this swirl valve is good for the low revs or the motor is more free when the intake is full (with the second hole open) at low Revs too. My motor fell as occluded when the revs are under 1200. the swirl valve are good for the emission when the revs are low, but the engine are not happy for this. This is my question......
What was the symptoms that led you to change this?, I have noticed leak in same olace and car runs like crap , black smoke , turbo works on and off and MAF code comes up, it has rough idle and sometimes wont rev
May I ask what the advantages of removing these flaps?
Thank you for this video! Do I need to instal any soft on the car after swirl flap deleted>
Nope
Will be looking at mine and using your code soon as I have the same leak. What about the egr o rings? Change them too? I'm planning on having it all apart to clean.
Nice one mate!
When you say if they “ do not need doing “. Well. How do you personally tell. There’s no warning. And it’s not all about the bar breaking. The flaps themselves go brittle and break or snap and drop into your cylinder. So you’re basically recommending that then. I beg to differ. But hey,..🤷🏻♂️. Each to their own I guess. 😉👍
I recommend removing your intake manifold to clean it and then inspecting them at the same time👍🏻
@@GeorgeAusters i just bought the 33mm delete kit ,..blanks,..but looking at my engine it looks like theyre alredy removed anyway,..
how much time did it took u to get the swirl flaps out and put everything back together?
Hi, great explanation and job, can I ask you please how long it takes to change swirl flap rail if its done at garage in one day ?
It’s not replaceable on this manifold
Hi George. Thanks a lot for the helpful video. Does a removal of the swirl flaps affect the durability and functionality of the DPF on a N47 engine? My driving profile is approx. 70% highway (80-130 km/h) and approx. 30% city (mean speed approx. 30 km/h). I understand that one can manifest a loss in torque only at low rpm, say at lower speed. I have removed the swirl flaps already but did not touch the EGR. I realize an increase in fuel consumption (approx. 10-15%). Is there anything I should also do with the EGR? Thanks a lot. Kind regards, Edward
But why after delete flaps, and cold start, engine makes terible sound, but just when start, when engine is warm, the car start whit no bad sound
Great video. Thanks!
I'm about to have my swirl flaps removed/deleted using rubber gaskets on a 520D 2014. My mechanic suggests it needs a 'Stage 1 Overlaying Remap' doing after removing the flaps, to stop the message coming up on the screen. Is this true?
Thanks
It's true
If there is no swirl flaps at all, wouldn't egr error come up as the air mass control by swirl flaps don't exist anymore? please help. I consider removing them next month. I'm worried I might get permanent Engine check light because of that...
Thanks. The Dutch
I have bmw 535d msport 2011 I just vant to ask you iff you take out swirl flaps? You need to do something whit computer to delete is wall or no thanks
Will it be ok to delete for bmw 116d 2017
Hi george thanks for the video great help. Did you have any error codes prior to removing ? My 47 3 series 2008 has rreduced power error. Is that what you had too ?!
Thanks in advance
might sound funny but ive only seen you putting the blank on actuator..not on flaps ..why is that?
Is swirl flaps just for diesel engine?
Can I install swarl flaps with all emissions intact or this one works for emissions deleted vehicle
Hi George just came across your channel today. I had an engine management light on my e90 325d 2010 , the AA said it’s a swirl flap issue, my question is that is my car still safe to drive ? No issues with performance. Thanks
Hi George, many thanks for (as always) informative and well-explained videos! Well done pal.
Please clarify whether the leaking manifold can be linked to a whistling sound when accelerating (over 1,500...2,000 rpm) ?
The whistling sound is quite noticeable and seems to be coming from the top of the engine, not from the turbo's side. The car pulls but should do better.
Possibly yes!
can you do it in my car too?I have 520d n47. Thank you
Great video mate! really helped me delete the swirl flaps on my N57 X6. However, i am getting an EML light for the swirl flap actuator, do i need to code it out? map it out? or simply leave it disconnected?
Is it still plugged in?
@@GeorgeAusters yes it is
@@GeorgeAusters Hi George, same question here.. Do I need to decode the actuator? or leave it disconnected as when connected it throws the error onto the ecu. and I was told that the dpf may not regenerate if there's an engine error stored for the swirl flaps. Please let us know your advice will be much appreciated 👍
Hi, I drive a g30 530d; done 40k miles (mainly motorway). Its popped up with swirl flap actuator error on ISTA.
I haven't removed the intake manifold yet to physically check.
Is there a chance its due carbon deposit of cheap ass supermarket fuel (which i always buy)?
And would switching to a better grade fuel remove the carbon, restoring the actuator's function?
Also would driving at higher revs help get rid of some the carbon build up? i rarely rev past 2000.
@GeorgeAusters If the flaps are removed, for either prevention or too much play, would a tune/remap after their removal correct the loss in power at low revs and mpg?
Unfortunately not
George, great vids pal!
So no swirl flap delete on a F30 msport n47?
Thanks Hollie. I wouldnt recommend it! They can actually be replaced on that engine if you want to.
@@GeorgeAusters Thanks George, keep doing what your doing.
I already have this boost leak that is already causing my MPG to be shit, will this actually reduce my MPG more or will it just reduce it from the quoted 58mpg?
Does any boost pipes come of when doing a swirl flap deleted a Mechanic done a swirl flap Delete on my bmw 330cd there is a loud scream sound after 2000rpm and on motorway the car cuts loads of power and struggles to go over 3000rpm. Thanks
I want to do the EGR and DPF and I’m told to do the swirl flaps too? Is there a reason for this based on what I want to do? This is on a 123D E88. From what you say about losing MPG etc I don’t think I wanna lose that. Thanks, Ben
Man, you forget to mention what n47 because n47 177cp and n47 184cp , has different intake mainfold .To the First one you can not replace swirl flaps and to the second one you can Buy swirl flaps separately .Also , is different procedure remove the intake mainfold , also to remove swirl flaps .
I searched a lot for this information when i wanted to replace the flaps for my n47 e90 LCI and nobody Tell the difference
I have a e93 2.0d 184 bhp n4720d engine. Can I blank mine or can it not be done on this model ?
I am so close. All 5 bolts held up and it’s off at the front and rear but just feels like something is still grabbing it. The egr pipe that is shown here -how does that release ?
Just held in by the o-ring and the bolts that keep falling back into their threads
@@GeorgeAusters thank you. Will keep going with the wiggling !
Have anyone tried to change oring/seal placed on the rod itself and knows its dimensions?
You can’t, it’s not a replaceable part unfortunately
@@GeorgeAusters why not? I don't think it's permanently mounted on the flaps rod. I watched some videos where people removed this seal after removing the adjuster lever without removing the rod itself from the manifold.
The fact is that BMW does not sell this seal separately, but nevertheless there are a lot of companies that remanufacture these manifolds and therefore have to replace this seal.
I will be researching the topic, because I have a feeling that in many cases if the flaps are ok, just replacing the sealer would take care of the manifold leak issue that many people face including myself recently.
If anyone has this sealer left please measure it and provide the dimensions here.
@@Prez_s Did you find out anything about it ?
@@rapidhunter7387 yes, there are two seals on rod placed under lever which can be seen after you take off actuator. After removing manifold my flaps was ok, so i replaced second seal and everything looks to be ok. No leaks or boost drop. Unfortunatelly i cant tell exact dimensions of oring/seal used - ive found few od them on my fathers workshop and choose one which fited best. Of course manifold needed to be clean since my car have about 250kkm.
Great Video! Remove the intake manifold only or Need to make too a new data in ecu for the intakte manifold?
Thanks 🙏
I have deleted the dpf and I replace it with a other tube it could be big issue without the remap?
Yes, needs to be mapped out
After place the delete kit does it need to be plugged in the computer to remove any other codes or faults ??
What needs to be done ??
Hi,ihave a question. Shoud i after removing flaps to be turned OFF and sofftware? The engine will not go into emergency mode? BMW N47
No need to be coded out
@@GeorgeAusters and the adjuster unit on or off?
Can you not reuse the original gaskets?
You can but best to replace👍🏻
How much worst is the mpg on comparison from before and after?
About 5mpg from my experience
I George I have the 530d f10 when I take the rod out and put the kit on do I not have to put the rod back on do I just leve it off the car for good can you let me no pls thanks Shaun
You can leave it off
@@GeorgeAusters thanks mate I will let you know how I get on
so what engine do i have. 2008 2 l diesel. air intake manifold doesnt have a swirl valve actuator
Guessing you have the 18d model?
@@GeorgeAusters yep
You said that the flaps should not be deleted before.
Did you watch the video?
hi I've taken it all off to remove and can only find 3 out of the intake manifold. lol any suggestions??? 120d m sport 10 plate
Keep looking
going to take the rocket cover off an hopefully its bouncing round the top of the valves. fingers crossed @@GeorgeAusters
I have a question about my 2016 BMW X5 F15
i have cleared everything and now after two months the same error code 2C3200 came back again. the car is tired but sometimes when i turn it off and start it again it runs like normal but most of the time it has no power do you know what it could be?
With an EGR delete, will it affect the emissions test and potentially fail the MOT..?
yes
After seeing you EGR PIPE on your intake manifold has a screw plug going into it and not a sensor any idea why? as mine has a EGR temperature sensor part number 7811913 on eBay going into it and not a screw plug this is the n47 engine still, then 11617811200 part number for pipe
How does it connect on the other end ? Does it just push on or is there a bolt that hasn’t been mentioned here ?
Hi george. I was considering getting my swirl flap delete as my 520d n47 is on 178k with original swirl flaps car has been carbon cleaned not to sure if that would help swirl flaps any advice would be appreciated 👍

@@GeorgeAusters thanks mate 👌
i have already deleted my flaps but now I have to take everything apart again because the high pressure fuel pump is making noises and car stalls when started cold
I've just done one of these recently on an 11 plate 118d, rail pressure too low in ISTA readings should be over 300 bar. Fitted second hand HPFP & LPFP (£140 for the two) but the entire fuel supply needed to be stripped for a thorough clean (or done in situ) as the pump breaking down will fill the high pressure and return lines, tank and low pressure pump with metal swarf.
The high pressure pump sprocket puller from a N47 timing kit can be used to lock the sprocket in place to allow you to change the pump without removing engine or gearbox (as many forums suggest needs to be done, they're wrong - there's plenty of room even on a e87)
Here's what I did in brief
1) Removed high pressure lines, rail and sensors for cleaning
2) Removed injectors stripped and cleaned with carb cleaner. Spray into the nozzle make sure you get a good spray pattern from all the holes. Doing this on kitchen towels really helped to get everything in order on the first couple, then it's easy. Use a decent 6 point hex socket or spanner on the nozzle, they are tight and easily damaged. Use new crush washers when refitting, cut seats if required.
3) Dropped tank and cleaned with degreaser/soapy water & cloths
4) Removed fuel supply & return lines and cleaned thoroughly
5) After re-assembly prime/purge HPFP using the fuel bleeding service option in ISTA before trying to start the engine (also when changing fuel filter).
I also dropped some magnets in both sides of the tank and inside the LPFP by the return pipe for a little more assurance (BMW recommend to change everything).
Good luck with your repair!
CARL MATE, can you help your old mate "TERRY" 😠only kiddin, anyway got an e61 520d 6 speed manual, HAS DONE 163000 miles, went to yarmouth and back the other day, roughly 150 miles each way, never went above 70, mainly between 60-70 and that`s gospel, can`t get the trip meter to go over 51.3 MPG, at 70 mph the rev counters showing about 2000 rpm, i thought these were good for over 60mpg on a steady run, any ideas mate ?

might whip the inlet manifold off this weekend, get 1/2 a dozen cans of Mr Muscle and hit it hard, when the car is re -mot`d with a nice 12 months , i`ll probably remove the EGR system completely, i`ll obviously ONLY be using it "off-road" of course 😇😇😇😇
Been trying for ages but I just can’t figure out what ur talking about with the ECU plugs they’re bastards and I can’t undo them
Ive been trying to find if my car even has them fitted but im getting yes and no. Its a 2012 E91 318d. Ive heard the 18d engines dont have them fitted? Hope yoy can help. Cheers.
18d don’t have them👍🏻
@@GeorgeAusters absolute life saver, new to BMW so that's a massive help. Thanks very much
Good day George.. I have e60 525i n52 petrol.. I did change the swirl flap outside manifold but having problem with swirl flap inside manifold.. is it advisable to just delete the swirl flap with installing the kit or replace the swirl flap.. thanking you in advance..

i don't understand why you would do this, adapting your engine so it is down on power and more thirsty
I did it just to show how to, I replaced the intake for a brand new one
@@GeorgeAusters Gotcha 👍, what prob's does flap failure cause? limp mode? can you still drive with flap failure or is this a quick fix until (or if) a new one is fitted
@@GeorgeAusters have you attempted glow plugs removal? seems a scary job
👍🏼
I don't get it, why would you use some kind of aftermarket plug? Just glue that hole with epoxy or get another used intake manifold that doesn't have flaps from the factory... Also, why are you leaving actuator if it's no longer doing it's job?
Actuator seals the bung in place
Great video George, are you interested in selling the intake manifold.? I’m serious, Mines melted, Cash on collection.? I did send you a Facebook message regarding egr delete but I guess you get quite a few now 😂
I had to give it in exchange mate
No worries mate, I lost boost a week or so ago, looks like my egr has stuck open and melted a hole like you said in your video, I’ve found a inlet manifold for £130 delivered from a bmw breaker (£795 dealer part plus 2 week wait) but now I want a swirl flap delete For peace of mind, fancy the job mate.? Northants.?
Think you should raffle off your next project car, £1 a ticket no limit on tickets, could raise your channel a decent amount for future work
If you want the swirl flaps deleted then may be best to get the 18D manifold without the swirl flaps. Either that or get a reinforced one like I installed.
Yeah I was thinking about doing a raffle of some sort in the future!
I had a hole in my intake manifold on E61 N47, bought another one from breakers and it did not have swirl flaps. After 2 weeks exhaust started giving black smoke on acceleration at high gears and loss of power is noticeable. So it is kinda worse without flaps. New aftermarket manifold can cost around £200 with flaps motor.
I agree, like I said in the video, I recommend NOT to remove them👍🏻
@@GeorgeAusters Just found out today what was actually the problem with power loss and smoke: the famous (temperature or flow?) sensor's bracket on the Air Charge (a.k.a. intercooler to intake) pipe tearing off. I was blaming missing swirl flaps, but apparently it was just that stupid crack at the sensors base, just like you showed in one of your videos. But I wasn't going to pay £300 for a new pipe due to such a small crack. Easily fixed in 15min with several turns of black rubber self-hardening adhesive sealing tape from halfords (£6.50) Got all power back immediately and no more smoke! Jeez...
@@devnull256 Common problem, happened to mine too and I replaced the whole pipe for new👍🏻
@@GeorgeAusters well, yeah, you probably got it for free from one of your sponsors :)
I removed mine at 150K and didn’t come out that simple 😂, there’s a blanking plate for the EGR pipe going to the head once EGR is deleted too as there common for leaking
How have your results been since blocking off the EGR? Did you tune the EGR out of the computer so your check engine light is not on all the time? If so, what did you use to do so? I have a 2015 328d that id love to delete the EGR on but don't want a check engine light all the time.
@@theprodistini2590 you need remap for light to come off , alientech kess 2 , 3 cheaper would be asking somebody to do it for you
Complete nonsense to delete the flaps, more 5 to 10 mpg and less power before 2000 rpm ... better to replace or clean it ....
Yeah till it they break and fly in the cylinders
@@Dct.Stephen just replace it ... most bmw break ups are lack of maintenance from owners
@@gafrancisco yes that’s 100% true. People can’t take care of there shit, kinda sad.
