I did mine 2 years ago and again today. 2 years ago I watched your video and today again. Thanks very much. I could send you some pictures of the cleaned Egr before I put it nach tomorrow. I’m letting it soak until tomorrow so that it cleans properly. All the best
Thank you, your videos are life (and wallet) saving for those of us who still drive these old magnificent german cruisers. Nice and easy job once you see it done, took me less than 2 hours to replace the valve, as the manifold didn't look that bad so didn't touch it.
Hey man! Want to thank you for this video and for having this channel! :-) Your videos are very useful and very easy to follow, you are doing an excellent job. I had big issues with my engine, and even Audi Zentrum Leipzig couldn't find the problem, but this video solved it! I did everything as you described, and also changed the DPF pressure sensor, and regenerated the DPF. The car is like new again. It went to limp mode three times after i cleaned the EGR, manifold and TB, but after some driving the fault codes disappeared. Also, the two bolts on the EGR-return (cooler) were 8mm HEX on mine, not 6mm. But maybe UK cars are different, idk? Once again, thank you very much, and keep posting more vids! Greetings from Norway!
Many Thanks for video, just what I needed to finish a job I had already started. I didn't think of using a 8mm Allen key for the 12 star hex bolts on the exhaust gas pipe. I was going to go on line to get a new bit (buying new tools always fun), your solution of using a 8mm allen means I can probably carry on now! Also thanks for the tip on just moving the cooling pipe and not removing it, its saved me some time (I was going to disconnect it). Excellent, stuff you are almost as good as Edd China (trust me, in my book that's a big complaint).. All the best!
I was told by a mechanic earlier on that after I've changed it I should use an injector cleaner OR put in about 2 liters of Petrol in with the diesel and run that through as it does the same as what the additives do, apparently. Try at your own risk, but it makes sense and should work pretty well. Haven't been able to find the air intake manifold gasket yet so I'll just have to clean what I can reach without taking it off completely. Thanks for the video dude, it's pretty damn good!
Cheers pal.took my car a3 se 55 plate into garage.said cost 400 because its a big job.showed garage owner this video he was shocked lol.170 quid..all in.great vid thanks
would just like to say thank you mate i have watched a few of your videos....they are good and well explained ....you have a lot of patience and appreciate the time and effort you do to make these
After I've watched your video....I'm in about to clean mine myself...Gonna buy the EGR cleaner and the gaskets set, so that I can dive well :) Great video!
Your video shoot is clear, very well planned and executed. Thank you very much!! I have not attempted this repair yet. I must gather enough energy first. I wonder how serious this EGR problem is. My EGR indicator (on the dashboard) comes ON/OFF sporadically. But it has been constantly ON for the last two weeks. This morning however, it turned OFF after I started the engine. A6 C6 4F 2011.
WOW!! Thank you very much for the research and all write up for me. I can't hear any noise for the leaks so must be other options I guess. I learned quite few things from your vids mate so please keep them posting as they are very useful for dumb like me😃
Excellent video. Well done. My EGR is leaking oil and garage wants to replace it. I wonder if it only needs a new gasket. I can do all this work but my problem is time. Great to know though what exactly is involved.
Great video thank you. Just cleaned mine yesterday with your instruction no problem. Ended up putting a new egr on after all that cleaning lol. Love your channel ;-)
Thanks for the great review! Made the job so much easier and explained really well! The allen key tips and loosening the coolant pipes (which get right in the way) were lifesavers too. My EGR valve was horrid and full of carbon - so satisfying to clean but took about 10 old tea towels and made a mess everywhere. I used about seven pairs of gloves also. I didn’t take my manifold off because I couldn’t get the new gasket the same day from Audi and yours looked fairly clean but it seems to have fixed my random intermittent loss of power. I only have one question… When are you making the one about replacing the turbo and the injectors ;-)
Sorry Dave, I don't have that car anymore - there is a age limit for taxi licence. I drive 2012 VW Sharan now. Thank you very much for nice words though 😊👍
Im doing this sometime in spring. it will be interesting to see how coked up the intake manifold and egr valve is on my BKD engine. The layout of the engine is similar to mine
Could you please tell me what are the names of gaskets as they have them in shops. I'm in the UK also, and when I check on eurocarparts I cant find any of these. Thank you very much, and thank you for your videos. I've learned a lot and I did enjoy them quite a bit to be honest :)
I don't think Eurocarparts will sell them, it must be dealership or vw/audi shop. No names - just explain where they going to and they will find them in catalogues.
very good video mate am sure this will help me out in the next few days on my A4, B7 2.0 TDi it looks like the same engine so i will let you know if there are any differences :) I know the duel mass flywheel is shot as there is a lot of shuddering so that might be next on the list
I wonder if another (4th) gasket is needed between what you called the throttle body and the EGR. It is the shiny part you remove first. Please advise.
Great video mate!!! I have Audi A6 4F and have problem with Clock Spring Sensot who is into the Steering wheel and control ESP. How to find out what part need to buy without opening Steering wheel ? Is that posible? tnx
Great video! I just cleaned my EGR and the car goes like new :D The engine management light is still on though. Do I have to cancel it with the diagnostics machine?
EGR pipe comes after throttle body. If someone blanks it, they normally blank it with little special metal plate. There are lots of talks about how necessary that procedure is, also in recent days - how legal it is. Little research would help :)
Hi mate great video, my problem is intermittent, sometimes will not accelerate, fault code is po404, removed and cleaned the egr , still same fault code and still intermittent acceleration any ides thanks
Sorry Trevor, probably there can be few reasons. That's what Google says: P0404 is a EGR circuit code. You most likely have an exhaust or intake leak which is why it's running rich. Check the engine bay for soot or oil stains near the intake or exhaust piping. Make sure to inspect the back of the engine. Check for exhaust system leaks?
After viewing this video, I subscribed to the channel on the strength of a very good video. I followed the instructions and cleaned my intake equipment. After reassembly I have a lack of power and lots of black smoke at low revs, checked everything, seems ok, any ideas,thanks.
@@wawayltd thanks for the reply, if anything it behaves like an air leak. There are no fault codes or lights. All was nice and clean, I mean really is a simple job and easy following the video. My friend, a garage owner is puzzled, Thank you, Rod.
@@rodneybrown8620 Not all fault codes come up with light on dash. Scanner must be capable not only to scan OBD errors.. I wish I could help you, but it needs to be seen. Did they check it for leaks? If mechanics puzzled.. I don't know what to suggest.
Hi, VERY HELPFUL VIDEO !!! Is there anyways to Clean EGR and Manifold without opening or removing parts.... because I feel diesel engine always generate carbon in side...Any suggestion ?? Regards
There are ways to do so, some kits are sold. Have a look here on UA-cam, but.. I don't know why - it is pretty simple to take it out and see what's going on for yourself ;)
IM WONDERING WHAT SORT OF MILEAGES ARE COVERED BEFORE THIS KIND OF CLEANING IS REQUIRED AND IS THERE A DIFFERENCE IN BUILD UP BETWEEN PETROL AND DIESEL ENGINES THANKS FOR GOOD CLEAR TUTORIAL
Diesels are normally more dirty, because fuel contains more carbon. Especially if turbo is not in great condition and pushing oil into the intake, it won't take long for gunk to bild up. Luckily in this car it's easy to check/clean. My current car 2012 VW Sharan has a bit more difficult access to egr... But nothing is impossible :)
Thank you for this awesome video, my car is misbehaving loads and the only error code is egr sensor 1. Ive had the egr deleted along with the egr cooler pipe removed many years ago but I think I need to follow these steps and replace my egr cooler and egr. Hopefully this will fix it.
If your EGR was removed time ago, they probably didn't re-program ECU, so it doesn't know what's going on with it. If you are going to put it back, then it might need another ECU adoption..
great detailed video,the engine looks exactly like my audi a4 b7 2.0 170 hp ,a would like to clean it as well but unable to find all them gaskets you mentioned please help thanks
Hi, great video. I just bought an A6/C6 Avant with same engine and going o do my first service on it. Going to do egr cleaning same time, any chance you know the part numbers of the three gaskets you used? Thanks in advance.
Gaskets are pretty cheap even if you're buying them from dealership. They were like 3 quid each - I just rang dealers and explained where they go - sorted :) Don't know part numbers for them.. Don't really need to.
Hi first of all, great video! I have a b6 Passat with the same engine. Mine will start and stall immediately and the throttle body/egr is making a ticking/knocking noise after it stalls. Does this sound like the egr is blocked?
Hi Tom, when EGR is blocked car should give you an error. Mine didn't. I had it stuck in position "open", and engine was suffocating in it's own exhaust gases. Throttle body normally makes ticking sound when engine stops - it shuts and opens again, but by default it should stay fully open, because diesels always should have sufficient amount of air and power is regulated by fuel injection.
Oil normally comes from turbo that pushes air into intake. In small quantities it's pretty normal, but when seals in turbo bearing wear out more and you get too much oil, (normally it's burning with white smoke and smells similar to burning plastic) that means turbo needs replacement or rebuild. But don't just take my word for it and go and spend your money on a new turbo. I'm not professional, I didn't see your car - I'm just sharing my experience. However, cleaning EGR is always good, but sometimes it can't fix all problems.
Hi Ioseb, never done N75 before.. I'm pretty sure it would be easy thing to do. But you know, just spent good couple hours trying to find proper instructions in my manuals - for some annoying reason I can't find them! I got almost everything from boost system - replacement of the whole turbo, intercooler, that little sensor that sits on intercooler... but not the N75!! As soon as I find any info, I'll let you know. I've found this little video, where some guy changes N75 on his tdi Golf, but I don't find it very informative, it's only 32 seconds long :) Here it is: How To: VW Golf TDI PD N75 Boost Valve Replacement (Pressure Control Boost Valve) Fitting and Repair
Hi there, thank you for the quick replay. I have watched that vid already and did not find very formative for my case nor location of the part is the same. The sensor under air filter is not the same one is it? Im sure you have the video how to change the air filter. I am getting over boosting faulty code when car goes in idle mode very randomly but happens on hard acceleration after turning car off and back on again everything is normal as it should. Got exact same car as yours (best car in the world😁)
Ioseb Khizanashvili I do have a video about the airfilter... The sensor behind airfilter (if it's the one you mean) is MAF sensor: How to change Mass Air Flow (MAF) sensor on Audi A6 (C6) I don't think it would cause overboost fault code. This is what I got from volkswagen forum about overboost code: VAG Error Code: 16618 EOBD II Error Code: P0234 Fault Location: Boost Pressure - Regulation Limit Exceeded (Overboost Condition) Possible Cause: Malfunction Indicator Lamp (MIL)(K83) ON. Boost Pressure too high. Reduced Power Output. Hoses incorrectly connected, disconnected, blocked or leaking. Boost Pressure Control Valve (N75) faulty. Boost Pressure Sensor (G13) faulty. Turbocharger (TC) stuck/faulty. Possible Solutions: Check Charge Pressure Control System. Perform Output Test (to check the Turbocharger (TC)). Perform Basic Setting (to check the Charge Pressure Control). Perform Pressure Test to locate Leaks. Check/Replace Boost Pressure Control Valve (N75). Check/Replace Boost Pressure Sensor (G13). Check/Replace Turbocharger (TC). As you can see quite a few things can go wrong and it needs a closer look..
+michael jagger If it wasn't clogged up, you shouldn't feel much difference. Once I had EGR valve stuck in position 'open', that was trouble - power loss and misfire, because exhaust gases were coming back into cylinders where engine needed more air. It's good to give it a clean once in a while.
Hi mate. Quick question - I cleaned everything just like in Your video and re-asembled correctly but the check engine light is on now. All the plugs are on and Im sure theres no technical fault in the way I did it. Did You ever had anything simillar?? Audi a6 c6 2.0 tdi. Will get it on the VAG tomz. Cherrs J.
Yeah dont remember the code number but the egr valve was stuck open. Took it apart and I discovered that there was a small bit of very hard black residue jammed where the valve arm is turning so after I took it out it works normal. Thanks for Your videos, they helped me lots when working on the car.
Hello....I have 2006 a6..same engine as you are working on...I have p4050 error code...egr sensor 1 low...any advice on how to fix this problem...would cleaning egr valve help??...thanks in advance..
Hi Paul, sorry I don't have experience with this code. Cleaning EGR in this car is pretty easy, it's always nice to have clean EGR system, but whether it will help that fault code - I don't know sorry
@@wawayltd Hello! How are you there? The code is p0016. It's something with the camshaft or the crankshaft. Last June I changed the cambelt. The mechanic changed a metalic piece on which the belt turns. He said it's worn. It's likely the cause of that code. Thanks for your help.
@@mohammedzahboune824 2009 was the year when VW was changing from PD engines back to common-rail. If it's a PD engine (engine code starts with "B") then it may have a problem if torsion value is not set during cambelt change. It can be done by garage that has VCDS and knows what they doing. Alternatively, maybe that mechanic didn't align camshaft/crankshaft properly..
Kajtar Erhard this engine is BLB, not sure what it looks like on BNA, also don't suppose you'll need a computer - you're not changing anything - just take out and put back :)
Hello ive a audi a6 2.7 diesel front wheel drive , europen version . Someone gifted me and i did all the filters and oil change , it has a check engine for air intake manifold + in computer there are some code for injector 2 3 5 , in highway for 130km it consume 8.6 lit , ive test it . But in the city for 20 km it consume 10 lit . Is this normal ? Does it has to do with intake manifold ? Many services here in albania told me dont do something to injectors becouse im gonna have more problems . What do you recommend me to do ?
Hi, great video like the other ones :) When it goes to cleaning maybe would be good to decarbonize engine as well (with water or cleaning liquid). Have seen some videos about that and as people say - it works. If you think it's a good idea tell me please how to do it. Where to spray that liquid in Audi A6 C6 2.0TFSI? Thanks
+WheelsAndMotors ordered some gaskets today as there weren't any in stock and the guy recommended to buy a seal as well that goes on the other side of the throttle body. any thoughts on that?
I have a video how to remove intake flap unit, but never tried to disassemble it, not sure if it's designed to be able to. You know what they like - buy new unit from us :)
Thank you so much, your tutorial is very detailed, you are awesome...I have so many questions! Now I finaly feel brave enough to clean that thing. I really hope that it could solve at least one of my problems. If the cleaning doesn't help. Do you think that deactivating the EGR is a "good" idea? 1.) When I shift from 1-2 gear, I hear a strange "clicking" whistle noise. It's hard to describe it. Maybe my Turbo is dying...or maybe the problem is EGR related. Any clues from your side? :) I have exactly the same engine (4F 2.0 TDI - BRE - 2006) btw 2.) No power in first gear at all. 3.) rough tickover, bouncy rev counter sationary with judder Cheers Eddie
Some people block EGR. As I understand, it won't harm the engine if intake takes only clean air and no soot and exhaust gases. Clicking-whistling when moving off? Maybe turbo, maybe clutch - I can only guess...
I bought my gaskets in local dealership. They are not expensive - even in dealership I paid about 3 pounds each. But EGR cleaner, I believe, it can be bought in many parts selling shops..
I have one more problem, I've seen that I have a leaking from egr, but the thing is I dont know if is the erg gasket or is from throttle body , that side between egr and throttle body there is a kind of red/pink seal do you think that i can replace that seal from throttle body ? thanks
Omontveroi S It looks to me that red/pink seal is the part of throttle body. If you don't know where the leak is coming from, I would recommend to replace gaskets first, see if it helps, and then go from that...
WheelsAndMotors Great video. Can you list the part serial numbers in the video description please. My car (A4 B7 2.0 TDI 140hp) went into Limping mode and will take on this job before taking it to the shop and look into whatever other error it might have. SAme as +Abs Pabs I'm also having trouble sourcing the gaskets. Browsed Eurocarparts and could not find similar ones. Called them. Got directed to local shop - Kingston - where they quoted me 50 pounds including bolts! If you wouldn't have said 3 each i could have gone for it. Thanks again!
Tudor Popa Found part of the gasket serial numbers here: www.swdubs.co.uk/how-to/egr-valve-cleaning-replacement-audi-a4-tdi EGR Gasket - U03G 131 547 F Z30 Gasket Anti Shudder O-ring - U03L 131 547 B Z25 O-Ring EGR Cooler Pipe Gasket - U069 131 547 D DR1C Gasket Not easy to retrieve online though.

Hi WheelsAndMotors, Great Video ! Just wondering if you could help me out with a quick problem im having. I have had the DPF light come up on my dashboard & the car is now in (safe mode), I have recently used the DPF regeneration liquid and taking it for a drive up the motorway (50 miles plus) , still nothing had changed. I took it to a local garage for diagnostics and it came up with a fault code saying it is my EGR valve. That mechanic then told me that I have to buy a new EGR valve for £350 then pay £250 labour to fit it in, but something is telling me not to proceed with that as I doubt that it is going to work. I then ran into another mechanic who I have paid to take out and clean my EGR Valve; after watching your video I now know that he has taken out the 'Flap Motor', and I have been scammed, but I don't know who to go to or what to do to resolve this issue. What do you suggest? Sorry For the essay
Hi, is the engine in your A3 any similar to the one in the video? On these PD engines it's quite easy to take them out.. Next generation common-rail C engines are a bit more tricky..
WheelsAndMotors yes it’s very similar if not the same 2 litre engine 61 reg . I’m sure the EGR valve and everything is the same as in this video. However I’m not confident enough to attempt to take it out lol !
In 61 plate it might be different. My current car VW Sharan is 61 plate and EGR cooler and valve are one complete piece and located under DPF at the back of the engine (At the back, because unlike A6 where engine is located along the bonet, in Sharan it's across). I can't prove or disprove what exactly your mechanic has done. I would recommend to go there and have a word about what has been done.
@@user-SophiaJ I think HAAS is a good brand (if it's not something trying to be HAAS). I had something from them - oil pressure switch or AC pressure sensor or both... Should be good. But check warranty terms with seller.
Well i did this cleaning this weekend and my intake manifold was literally blocked or clogged with carbon so as my egr, wow fking god i wasnt that horrified for ages
ok, thank you very much, today i took out again the throttle body and I took the egr as well and I cleaned it but that doesn't mean that i fix it , anyway I think that must be replaced but I hope that maybe you are going to give me a way to fix the old one otherwise a new one is £250 not cheap at all , but is original from audi , i found one at eurocarparts for £170 but i don't think that this one does have the same quality as audi one ! thank you again
I spoke to one mechanic (the real one ;) ) today.. Yeah, he said that it's likely EGR valve faulty, but he would need to see it to confirm that. Also he said - it happens to EGR valves, and if it's not too messy and doesn't affect performance, you could drive it for a while till it gets bad.. Talking about quality parts bought from dealership - I don't know, I'm always happy to use GSF of eurocarparts, unless it's something specific that can be bought only from Audi. Some parts can be considered from second hand, but I'm not sure, if I would want to buy second hand EGR.. Unless it's really cheap and has some warranty and possibility of return for money (not credit note) Look, I've found one for 157.99: www.ebay.co.uk/itm/EGR-VALVE-AUDI-A6-2-0-TDI-DIESEL-04-08-BLB-BRE-ENGINE-CODES-O-E-MANUFACTURER-/300787440204?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item4608541a4c
thank you very much for your time and everything but I took out the egr and I replace it with a new one I bought direct from audi on internet and on eurocarparts could be found for £160 - £180 , i paid for the original one £240 is not that bad, anyway my audi is from 2008 and the egr is different not the same as audi a6, anyway somehow I am more confident if I know that the part is original again, thank you very much and hope you have a video to learn how to change the timing belt as well :)
Could be a good idea, but then you won't be able to access that sneaky-tricky bolt inside intake hole (the one I dug out from carbon in this video) - see on 7:05
Hi there, My Audi A6 2007 estate has engine management light on and when I drive now it won’t let me go over 40 mph , I put a code reader on and it came up 01826 so I erased the fault on the reader but the light has come on again and won’t let me drive properly again. Could this clean out help me. Kind regards, Paul. P.s. thankyou very much for your upload you are a credit to car engineers ⭐️⭐️⭐️⭐️⭐️
Hi Paul. This code 01826 points on steering angle sensor. It has nothing to do with the engine. Engine fault codes normally start with "P". Of course steering angle sensor is something that needs to be sorted out, because it affects your Traction control and ABS and lots of other things.. I'm not sure why it doesn't let you to drive over 40. When initially I had egr problem with my Audi, it didn't show engine management light. Cleaning EGR won't harm at it's always good, however I don't know what exactly going on with your car. Try scanning with VCDS? It's more comprehensive, rather than just EML.
WheelsAndMotors ...cheers mate, quick update , it’s been checked again with engine running and code reader plugged in and now it’s saying 01200 😤. It’s all bloody fun ain’t it.
Is it comprehensive scanner like VCDS (vag com) or just OBD code reader? Anyway, where your codes point is like ABS and steering angle sensor, stuff like that. I'm not professional, so I'm afraid I won't be able to help you. Hope you get it sorted easy.
My 2005 A6 2.0 Tdi had this done 4 years ago at 80 thousand miles. Its now has 164k and is starting to leak again. Is this normal... any idea what is causing the build up. Also how long does it take to complete the job and approx how much does it cost in euro. Thanks a mil for the upload!
I believe that carbon build up is inevitable, because exhaust gases are dirty and EGR system brings it back to intake. Also on older engines there's always a bit of oil coming from the turbo. But if you have oil leak on the outside - that would be sign of something faulty. In terms of cost - I only bought gaskets. Total cost from dealership about 10 pounds, which would be about 15 euro.
On this 2005 Audi, both EGR and flap motor didn't give check engine light when they were faulty, but it did show when someone scanned with VAGcom. Newer cars can show - my 2012 VW Sharan currently has check engine light - P0403 - egr control circuit. Anyway - on this Audi it's easy accessible to check or clean..
I replaced that pink seal but in the end I realized that in not that is something else the problem is the egr valve , on this egr valve is a small hole on it ( 2-3 mm diameter ) and the leak comes out from there, what do you think about that, something that I can fix or I need to replace egr valve ? my car is audi a4 s line 2008 thanks
A hole in EGR valve? How come there is a hole? If you have a damage, I suppose valve need to be replaced.. Could you post an image on my website? Then I can also show to some professionals...
That car was doing lots of miles/kilometers, I don't really know. I suppose it depends on how you drive it. Luckily in this car it's not difficult to take it out and check at any time.
Gaskets are not expensive even from a dealership. What I did - just called them and explained what gaskets and where they go - they just got right ones.
Hi. I have an Audi A4 2.0 tdi 170 bhp. Recently my coil light started flashing on dash board and error message came on it was the motor for intake manifold flap. Happened twice more and all I the space of two days. All error codes have now been erased and car is running better than before. It's been a week and all is good. Is this a sign that my motor for intake manifold flap needs replacing or a good clean would do. Thanks
Hi there I've got fault code 2009 on my a6 avant, engine management light is on and can't get rid of it. Was this what was happening with yours and if so did it clear after the clean down? Thanks
Not sure how to help you with this one Ross. I've looked in the web through my Torque app, looks like it might be pointing onto intake flap motor (throttle body), although if I'm not mistaken it has it's own code. Worth checking anyway. Here's couple links for you. This is what I found in the web regarding P2009: www.troublecodes.net/p2codes/p2009/?from=torque I also have a video about that intake flap, here is the link: ua-cam.com/video/RwQ1q-EcG58/v-deo.html
+WheelsAndMotors the bolts from the manifold.I had a problem,I have cleaned the manifold intake,egr and anti-shutter,but I didn't managed to tight the bolts from the manifold and the car started to give white smoke on the exhaust,because the oil that is cooled from the manifold passed the gasket and into my inlet. please tell me is it 22Nm for all manifold bolts? thanks
Hi, on german engine 2.0 tdi, like A3, if I blank the egr valve, does the car go in limp mode?? I did it in a ford mondeo 1.8 tdci 2008 and there is no problem to do without consequences.
Hi Sergiu, I don't have and experience of blanking EGR. There are lots of opinions whether do it or not. I think that it certainly keeps intake cleaner. Now I drive 2012 VW Sharan, it has nearly 250.000 miles, has DPF and I didn't have any trouble from EGR yet. Maybe they have learned how build it so it works? :) I don't think it should go into limp mode, however, as far as I know - some amendments must be done to ECU, because if it doesn't know that EGR is blanked it may calculate wrong air/fuel ratio. But, as I said. I don't have experience - maybe you can just blank it and forget it. Not sure..
I bought them in dealership, they are not expensive, not sure if they have specific names - I just explained them where they go - and they sold them to me.
hi! I have a A6 3.0 quattro s line 55 reg, the car is smoking white smoke.i've checked the injectors and it's sayng that they work just fine.can you give me any evidences please. thanks!
I have a p0404 code and limp mode on my a6 c6 2.0tdi. Ive done a carbon clean but still no joy. Should i just replace the whole egr unit as its making some pretty horrible noises. When i clear the codes power comes back but then goes to limp mode again after a short while when the code comes back. Any help would be much appreciated
Did you take it apart like in this video or was it some other cleaning without unbolting stuff? Yeah valve can get faulty too, so if it's clean, but still gives trouble - perhaps you need new one.
WheelsAndMotors not taken apart no... used a mobile carbon clean bloke. The black smoke that came out was biblical! Almost caused the block to lose all visibility so im assuming it was very very clogged up which damaged it
In that particular car EGR is quite easy accessible, maybe it's worth trying to clean it completely to shiny condition (like in the video), see if helps to get rid of the code.. If not, then probably new valve..
I don't know, I just bought it from dealership, explained where it goes and costed me about 3 pounds. Just had a look on eBay - it's more expensive :) Check this link: www.ebay.co.uk/sch/i.html?_odkw=intake+manifold+gasket+audi+a6+c6+2.0tdi&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.TRS0&_nkw=intake+manifold+gasket+audi+a6+c6+2.0tdi&_sacat=0
Thank you. I did this today. Load of black soot and crap in there. Used 4 cans of cleaner and still not completely clean. But had to put back together. Will clean it again soon. Great videos by the way. So glad we have the same car
so what kind of the problem come when the AGR valve & inlet manifoold is too dirty ? cause we have VW 1.4 tdi have a( big white smok & a bit engine knock )& cold start all this problem can be cause of that AGR Vave & manifold is dirty?
+wavu shabani Yes, when it's dirty it can cause different problems. The one I had - EGR was clogged up and stuck in position "open" - so exhaust gases were always coming back to cylinders, even when engine was cold and needed more air.
I cleaned my EGR valve today. What a difference to the performance! Could not have done it without this video. Thank you!
You're very welcome 👍
Glad if it helps.
Happy New year! 🎉
I did mine 2 years ago and again today. 2 years ago I watched your video and today again. Thanks very much. I could send you some pictures of the cleaned Egr before I put it nach tomorrow. I’m letting it soak until tomorrow so that it cleans properly. All the best
Glad if it helps 😎👍
Thank you, your videos are life (and wallet) saving for those of us who still drive these old magnificent german cruisers. Nice and easy job once you see it done, took me less than 2 hours to replace the valve, as the manifold didn't look that bad so didn't touch it.
You're very welcome Eddie 👍
Hey man!
Want to thank you for this video and for having this channel! :-)
Your videos are very useful and very easy to follow, you are doing an excellent job.
I had big issues with my engine, and even Audi Zentrum Leipzig couldn't find the problem, but this video solved it! I did everything as you described, and also changed the DPF pressure sensor, and regenerated the DPF. The car is like new again.
It went to limp mode three times after i cleaned the EGR, manifold and TB, but after some driving the fault codes disappeared. Also, the two bolts on the EGR-return (cooler) were 8mm HEX on mine, not 6mm. But maybe UK cars are different, idk?
Once again, thank you very much, and keep posting more vids!
Greetings from Norway!
Thanks :) Pleasure to see such appreciation :)
Many Thanks for video, just what I needed to finish a job I had already started. I didn't think of using a 8mm Allen key for the 12 star hex bolts on the exhaust gas pipe. I was going to go on line to get a new bit (buying new tools always fun), your solution of using a 8mm allen means I can probably carry on now! Also thanks for the tip on just moving the cooling pipe and not removing it, its saved me some time (I was going to disconnect it). Excellent, stuff you are almost as good as Edd China (trust me, in my book that's a big complaint).. All the best!
I was told by a mechanic earlier on that after I've changed it I should use an injector cleaner OR put in about 2 liters of Petrol in with the diesel and run that through as it does the same as what the additives do, apparently. Try at your own risk, but it makes sense and should work pretty well. Haven't been able to find the air intake manifold gasket yet so I'll just have to clean what I can reach without taking it off completely. Thanks for the video dude, it's pretty damn good!
Thank you :)
Cheers pal.took my car a3 se 55 plate into garage.said cost 400 because its a big job.showed garage owner this video he was shocked lol.170 quid..all in.great vid thanks
Wow, I can help real mechanic :) That's a honour! Thanks Martin :)
would just like to say thank you mate i have watched a few of your videos....they are good and well explained ....you have a lot of patience and appreciate the time and effort you do to make these
Thanks :) Glad if it helps!
Thanks!
Just for everyone to know, it's the same for Audi A4 B7 2.0 L BRD engine. I've just done mine. Thanks a lot for the video :)
You're very welcome 😊👍
After I've watched your video....I'm in about to clean mine myself...Gonna buy the EGR cleaner and the gaskets set, so that I can dive well :) Great video!
Thanks Ivan 👍
Thanks to you and save € 400 and just spend € 60 thank you very much friend, very good work, a hug, greetings from Spain !!
You're very welcome, glad if it helps 🤓👍
Your video shoot is clear, very well planned and executed. Thank you very much!! I have not attempted this repair yet. I must gather enough energy first. I wonder how serious this EGR problem is. My EGR indicator (on the dashboard) comes ON/OFF sporadically. But it has been constantly ON for the last two weeks. This morning however, it turned OFF after I started the engine. A6 C6 4F 2011.
thanks for the knowledge, a good old street mechanic
You're welcome :)
These videos are so helpful thanks for the good work!!
You're welcome :)
WOW!! Thank you very much for the research and all write up for me. I can't hear any noise for the leaks so must be other options I guess. I learned quite few things from your vids mate so please keep them posting as they are very useful for dumb like me😃
Really useful video! 👍 I now know how to unclip the electrical connector from my EGR...! 👏😃
😁 I'm not sure if unplugged connector would solve potential problems... Maybe?
Thank you very much you been a massive help with all your Audi A6 C6 videos.
You're very welcome :)
if i ever buy an a6 i will surely follow your channel!
Excellent video. Well done. My EGR is leaking oil and garage wants to replace it. I wonder if it only needs a new gasket. I can do all this work but my problem is time. Great to know though what exactly is involved.
Great video thank you. Just cleaned mine yesterday with your instruction no problem. Ended up putting a new egr on after all that cleaning lol. Love your channel ;-)
I'm about to give it a clean but wondering if I should just put a new egr valve to avoid wasting time, was yours still faulty after cleaning it well?
Thank you bro i could NOT find the screw inside the manifold for the life of me because it was under 5mm of slag
Hidden mysteries of Audi manifolds 😉
Thanks mate can’t wait to start mine tomorrow
It's pretty easy with this car, just a bit messy 😏
Thanks for the great review!
Made the job so much easier and explained really well!
The allen key tips and loosening the coolant pipes (which get right in the way) were lifesavers too. My EGR valve was horrid and full of carbon - so satisfying to clean but took about 10 old tea towels and made a mess everywhere. I used about seven pairs of gloves also.
I didn’t take my manifold off because I couldn’t get the new gasket the same day from Audi and yours looked fairly clean but it seems to have fixed my random intermittent loss of power.
I only have one question…
When are you making the one about replacing the turbo and the injectors ;-)
Sorry Dave, I don't have that car anymore - there is a age limit for taxi licence. I drive 2012 VW Sharan now. Thank you very much for nice words though 😊👍
love your videos. have you ever done a video taking to cog compartment off the EGR valve?
Thanks. No I haven't, not sure if it can be taken apart.
An excellent video thanks for this will use it to service my Seat Leon. Keep these videos coming really good.
Where do I get the gaskets from
Dealership or TPS.
Hélio Nice job .Thank you for this vídeo. I have a question. The battery must be disconnected first?
Thanks! I did it just with ignition out. Not sure about battery disconnection. I suppose, there is nothing wrong with disconnecting the battery.
Good work bro!👌👌👌
Thanks 👍
Great video 👍thank you
Thanks 🙂
Thank you for this video. Very helpful video
You're very welcome 👍
Im doing this sometime in spring. it will be interesting to see how coked up the intake manifold and egr valve is on my BKD engine. The layout of the engine is similar to mine
Could you please tell me what are the names of gaskets as they have them in shops.
I'm in the UK also, and when I check on eurocarparts I cant find any of these.
Thank you very much, and thank you for your videos. I've learned a lot and I did enjoy them quite a bit to be honest :)
I don't think Eurocarparts will sell them, it must be dealership or vw/audi shop. No names - just explain where they going to and they will find them in catalogues.
you are a star bro i have same car and luv your vids
Thanks Mawgan :)
Thanks for the sharing, it's very helpful to me.
You're very welcome, Richard :)
Cleaned it but still doesn't work will i need a new one then?
Possibly. Does it give any fault codes?
very good video mate am sure this will help me out in the next few days on my A4, B7 2.0 TDi it looks like the same engine so i will let you know if there are any differences :) I know the duel mass flywheel is shot as there is a lot of shuddering so that might be next on the list
I wonder if another (4th) gasket is needed between what you called the throttle body and the EGR. It is the shiny part you remove first. Please advise.
There is a seal on the throttle body. If your car is different and you had a gasket there originally, then it would be good to replace it.
I am just thinking if I well buy V70 or A6 they are Diesel and 2007, witch is best to buy? 👌👌👌🙏🙏🙏
I don't know much about Volvos. I suppose the one in better mechanicsl state, or the one you like more 🙄
Great video mate!!! I have Audi A6 4F and have problem with Clock Spring Sensot who is into the Steering wheel and control ESP. How to find out what part need to buy without opening Steering wheel ? Is that posible? tnx
I know one good website listing VW parts and their part numbers. Try this one:
www.oemepc.com/
Great video! I just cleaned my EGR and the car goes like new :D
The engine management light is still on
though. Do I have to cancel it with the diagnostics machine?
If the problem that light is about is solved, the light should go away eventually.. Do you know what is the code behind that engine management light?
Great video, how many miles has the car done ? Also try cleaning the manifold with foaming oven cleaner, it works great.
thanks for your help, can theegr be blanked on this engine with throttle body ?
EGR pipe comes after throttle body. If someone blanks it, they normally blank it with little special metal plate. There are lots of talks about how necessary that procedure is, also in recent days - how legal it is. Little research would help :)
Great videos just subscribed 👍, one question could you get away without changing the gaskets?
Probably. If they are not damaged, I don't think it will be a problem.
Hi mate great video, my problem is intermittent, sometimes will not accelerate, fault code is po404, removed and cleaned the egr , still same fault code and still intermittent acceleration any ides thanks
Sorry Trevor, probably there can be few reasons. That's what Google says:
P0404 is a EGR circuit code. You most likely have an exhaust or intake leak which is why it's running rich. Check the engine bay for soot or oil stains near the intake or exhaust piping. Make sure to inspect the back of the engine.
Check for exhaust system leaks?
Good job buddy
Thanks 👍
After viewing this video, I subscribed to the channel on the strength of a very good video. I followed the instructions and cleaned my intake equipment. After reassembly I have a lack of power and lots of black smoke at low revs, checked everything, seems ok, any ideas,thanks.
Sorry to hear that, are you sure nothing dropped in to cylinders, and it's all clear of soot?
Does it give you any fault codes?
@@wawayltd thanks for the reply, if anything it behaves like an air leak. There are no fault codes or lights. All was nice and clean, I mean really is a simple job and easy following the video. My friend, a garage owner is puzzled, Thank you, Rod.
@@rodneybrown8620 Not all fault codes come up with light on dash. Scanner must be capable not only to scan OBD errors..
I wish I could help you, but it needs to be seen. Did they check it for leaks?
If mechanics puzzled.. I don't know what to suggest.
Hi,
VERY HELPFUL VIDEO !!!
Is there anyways to Clean EGR and Manifold without opening or removing parts.... because I feel diesel engine always generate carbon in side...Any suggestion ??
Regards
There are ways to do so, some kits are sold. Have a look here on UA-cam, but.. I don't know why - it is pretty simple to take it out and see what's going on for yourself ;)
IM WONDERING WHAT SORT OF MILEAGES ARE COVERED BEFORE THIS KIND OF CLEANING IS REQUIRED AND IS THERE A DIFFERENCE IN BUILD UP BETWEEN PETROL AND DIESEL ENGINES
THANKS FOR GOOD CLEAR TUTORIAL
Diesels are normally more dirty, because fuel contains more carbon. Especially if turbo is not in great condition and pushing oil into the intake, it won't take long for gunk to bild up. Luckily in this car it's easy to check/clean. My current car 2012 VW Sharan has a bit more difficult access to egr... But nothing is impossible :)
Thank you for this awesome video, my car is misbehaving loads and the only error code is egr sensor 1. Ive had the egr deleted along with the egr cooler pipe removed many years ago but I think I need to follow these steps and replace my egr cooler and egr. Hopefully this will fix it.
If your EGR was removed time ago, they probably didn't re-program ECU, so it doesn't know what's going on with it. If you are going to put it back, then it might need another ECU adoption..
great detailed video,the engine looks exactly like my audi a4 b7 2.0 170 hp ,a would like to clean it as well but unable to find all them gaskets you mentioned please help thanks
I bought them from dealership, they are cheap.
Hi, do you need to make alignment ( vcds or by hand) after you clean it and put it back?
I have am audi a4 bre b7 2007 2.0 tdi 140 hp
No. You don't need a software for this job - it's just a valve.
@@wawayltd ok
@@wawayltd thanks
is the connection to the EGR also the egr sensor ?
Probably not. That connection is to control EGR.
Hi, great video. I just bought an A6/C6 Avant with same engine and going o do my first service on it. Going to do egr cleaning same time, any chance you know the part numbers of the three gaskets you used? Thanks in advance.
Gaskets are pretty cheap even if you're buying them from dealership. They were like 3 quid each - I just rang dealers and explained where they go - sorted :) Don't know part numbers for them.. Don't really need to.
Will try my local dealer then. Thanks
By the way, if you are looking for part numbers - try this website:
www.oemepc.com/
Hi first of all, great video! I have a b6 Passat with the same engine. Mine will start and stall immediately and the throttle body/egr is making a ticking/knocking noise after it stalls. Does this sound like the egr is blocked?
Hi Tom, when EGR is blocked car should give you an error. Mine didn't. I had it stuck in position "open", and engine was suffocating in it's own exhaust gases. Throttle body normally makes ticking sound when engine stops - it shuts and opens again, but by default it should stay fully open, because diesels always should have sufficient amount of air and power is regulated by fuel injection.
around my EGR is some oil and from the exsose coming white smoke and soot.do yo think it will be fix if I clean the EGR?
Oil normally comes from turbo that pushes air into intake. In small quantities it's pretty normal, but when seals in turbo bearing wear out more and you get too much oil, (normally it's burning with white smoke and smells similar to burning plastic) that means turbo needs replacement or rebuild. But don't just take my word for it and go and spend your money on a new turbo. I'm not professional, I didn't see your car - I'm just sharing my experience.
However, cleaning EGR is always good, but sometimes it can't fix all problems.
just done my egr as by your vid here my egr and manifold was so bad but mine was not dry it was like oily gunk is that normal??
It is pretty normal for older diesels to have some oil being pushed into intake by turbo. If it's too much - could be a sign of dying turbo
hi mate, grate vids as always, was wondering if you have one where it shows how to change Boost Pressure Control Valve N75? thanks
Hi Ioseb, never done N75 before.. I'm pretty sure it would be easy thing to do. But you know, just spent good couple hours trying to find proper instructions in my manuals - for some annoying reason I can't find them! I got almost everything from boost system - replacement of the whole turbo, intercooler, that little sensor that sits on intercooler... but not the N75!! As soon as I find any info, I'll let you know. I've found this little video, where some guy changes N75 on his tdi Golf, but I don't find it very informative, it's only 32 seconds long :) Here it is:
How To: VW Golf TDI PD N75 Boost Valve Replacement (Pressure Control Boost Valve) Fitting and Repair
Hi there, thank you for the quick replay. I have watched that vid already and did not find very formative for my case nor location of the part is the same. The sensor under air filter is not the same one is it? Im sure you have the video how to change the air filter. I am getting over boosting faulty code when car goes in idle mode very randomly but happens on hard acceleration after turning car off and back on again everything is normal as it should. Got exact same car as yours (best car in the world😁)
Ioseb Khizanashvili I do have a video about the airfilter...
The sensor behind airfilter (if it's the one you mean) is MAF sensor:
How to change Mass Air Flow (MAF) sensor on Audi A6 (C6)
I don't think it would cause overboost fault code.
This is what I got from volkswagen forum about overboost code:
VAG Error Code: 16618
EOBD II Error Code: P0234
Fault Location:
Boost Pressure - Regulation Limit Exceeded (Overboost Condition)
Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) ON.
Boost Pressure too high.
Reduced Power Output.
Hoses incorrectly connected, disconnected, blocked or leaking.
Boost Pressure Control Valve (N75) faulty.
Boost Pressure Sensor (G13) faulty.
Turbocharger (TC) stuck/faulty.
Possible Solutions:
Check Charge Pressure Control System.
Perform Output Test (to check the Turbocharger (TC)).
Perform Basic Setting (to check the Charge Pressure Control).
Perform Pressure Test to locate Leaks.
Check/Replace Boost Pressure Control Valve (N75).
Check/Replace Boost Pressure Sensor (G13).
Check/Replace Turbocharger (TC).
As you can see quite a few things can go wrong and it needs a closer look..
How much better did it run after this?
+michael jagger If it wasn't clogged up, you shouldn't feel much difference. Once I had EGR valve stuck in position 'open', that was trouble - power loss and misfire, because exhaust gases were coming back into cylinders where engine needed more air. It's good to give it a clean once in a while.
If I blank off the EGR will it stop the blockage?
Hi mate. Quick question - I cleaned everything just like in Your video and re-asembled correctly but the check engine light is on now. All the plugs are on and Im sure theres no technical fault in the way I did it. Did You ever had anything simillar?? Audi a6 c6 2.0 tdi. Will get it on the VAG tomz. Cherrs J.
Sorry my friend - took me while to reply... Did you find out what fault code it is?
Yeah dont remember the code number but the egr valve was stuck open. Took it apart and I discovered that there was a small bit of very hard black residue jammed where the valve arm is turning so after I took it out it works normal. Thanks for Your videos, they helped me lots when working on the car.
@@JerryPL1983 Thanks, glad you solved the problem 👍
Hello....I have 2006 a6..same engine as you are working on...I have p4050 error code...egr sensor 1 low...any advice on how to fix this problem...would cleaning egr valve help??...thanks in advance..
Hi Paul, sorry I don't have experience with this code. Cleaning EGR in this car is pretty easy, it's always nice to have clean EGR system, but whether it will help that fault code - I don't know sorry
yes, it does smell and the turbo doesn't make any stage noise...and it does pull really well.what should I check for? thanks

Hello there! Do you have any idea about how to fix evap leaks? Thanks a lot for your efforts.
Sorry, I have very little experience with petrol engines..
@@wawayltd hi! My car is diesel. It's a passat b6 2009. When I fill the tank it doesn't start immediately. Lately the check engine light has come on
@@mohammedzahboune824 What fault code is it giving you?
@@wawayltd Hello! How are you there? The code is p0016. It's something with the camshaft or the crankshaft. Last June I changed the cambelt. The mechanic changed a metalic piece on which the belt turns. He said it's worn. It's likely the cause of that code. Thanks for your help.
@@mohammedzahboune824 2009 was the year when VW was changing from PD engines back to common-rail. If it's a PD engine (engine code starts with "B") then it may have a problem if torsion value is not set during cambelt change. It can be done by garage that has VCDS and knows what they doing.
Alternatively, maybe that mechanic didn't align camshaft/crankshaft properly..
is it the same procedure on the BNA engines? do i need a scan tool to re-learn idle control?
Kajtar Erhard this engine is BLB, not sure what it looks like on BNA, also don't suppose you'll need a computer - you're not changing anything - just take out and put back :)
Hello ive a audi a6 2.7 diesel front wheel drive , europen version . Someone gifted me and i did all the filters and oil change , it has a check engine for air intake manifold + in computer there are some code for injector 2 3 5 , in highway for 130km it consume 8.6 lit , ive test it . But in the city for 20 km it consume 10 lit . Is this normal ? Does it has to do with intake manifold ? Many services here in albania told me dont do something to injectors becouse im gonna have more problems . What do you recommend me to do ?
Sorry my friend, I can't say much about V6 engines. Don't have any experience.
Hi, great video like the other ones :)
When it goes to cleaning maybe would be good to decarbonize engine as well (with water or cleaning liquid). Have seen some videos about that and as people say - it works.
If you think it's a good idea tell me please how to do it. Where to spray that liquid in Audi A6 C6 2.0TFSI?
Thanks
Lukasz Sieniuc Hi, I also have seen some videos, but never tried to do it myself.. So I can't say much...
What was the problem? Idel was rough or what? What was the reason for the cleaning
This time I have done just for simply cleaning. Before that it had misfire when starting cold. EGR was stuck in position "open".
hi, thanks for your video. what are the gaskets actually called? don't want to enter in audi shop and leave with the wrong parts. thanks :)
+arpi riki I don't know if these gaskets have names.. I went to dealership and explained where they go, and they gave me correct ones.
+WheelsAndMotors that's cool, thanks for your reply
+WheelsAndMotors ordered some gaskets today as there weren't any in stock and the guy recommended to buy a seal as well that goes on the other side of the throttle body. any thoughts on that?
I didn't know about seal.. But I suppose, if the guy knows what he's talking about, maybe it's worth to use a seal as well.
hi how would i remove the servo on the manifold that operates the flaps, as the manifold needs a good clean
I have a video how to remove intake flap unit, but never tried to disassemble it, not sure if it's designed to be able to. You know what they like - buy new unit from us :)
How much approximately would it cost in a garage to do !?
Sorry, I have no idea, it depends on a garage - you have to ask them.
Why don't you want to try yourself? It's easy!
Thank you so much, your tutorial is very detailed, you are awesome...I have so many questions! Now I finaly feel brave enough to clean that thing. I really hope that it could solve at least one of my problems. If the cleaning doesn't help. Do you think that deactivating the EGR is a "good" idea?
1.) When I shift from 1-2 gear, I hear a strange "clicking" whistle noise. It's hard to describe it. Maybe my Turbo is dying...or maybe the problem is EGR related. Any clues from your side? :) I have exactly the same engine (4F 2.0 TDI - BRE - 2006) btw
2.) No power in first gear at all.
3.) rough tickover, bouncy rev counter sationary with judder
Cheers
Eddie
Some people block EGR. As I understand, it won't harm the engine if intake takes only clean air and no soot and exhaust gases.
Clicking-whistling when moving off? Maybe turbo, maybe clutch - I can only guess...
Rough idle is a common problem with this car... Unfortunately, I don't know - would love to find out myself.
Did you ever get these problems sorted? I have the exact same problems, hoping the EGR clean fixed them?
can you please tell me where I can buy those parts ? can you give me the link or place that you bought those gaskets, please .
I bought my gaskets in local dealership. They are not expensive - even in dealership I paid about 3 pounds each. But EGR cleaner, I believe, it can be bought in many parts selling shops..
I have one more problem, I've seen that I have a leaking from egr, but the thing is I dont know if is the erg gasket or is from throttle body , that side between egr and throttle body there is a kind of red/pink seal
do you think that i can replace that seal from throttle body ?
thanks
Omontveroi S It looks to me that red/pink seal is the part of throttle body. If you don't know where the leak is coming from, I would recommend to replace gaskets first, see if it helps, and then go from that...
In regards to your gaskets where did you buy them from can't find specific gaskets anywhere?
Abs Pabs I bought them from dealership. They cost like 3 pounds each.
WheelsAndMotors Great video. Can you list the part serial numbers in the video description please. My car (A4 B7 2.0 TDI 140hp) went into Limping mode and will take on this job before taking it to the shop and look into whatever other error it might have. SAme as +Abs Pabs I'm also having trouble sourcing the gaskets. Browsed Eurocarparts and could not find similar ones. Called them. Got directed to local shop - Kingston - where they quoted me 50 pounds including bolts! If you wouldn't have said 3 each i could have gone for it. Thanks again!

Hi WheelsAndMotors, Great Video ! Just wondering if you could help me out with a quick problem im having. I have had the DPF light come up on my dashboard & the car is now in (safe mode), I have recently used the DPF regeneration liquid and taking it for a drive up the motorway (50 miles plus) , still nothing had changed. I took it to a local garage for diagnostics and it came up with a fault code saying it is my EGR valve. That mechanic then told me that I have to buy a new EGR valve for £350 then pay £250 labour to fit it in, but something is telling me not to proceed with that as I doubt that it is going to work. I then ran into another mechanic who I have paid to take out and clean my EGR Valve; after watching your video I now know that he has taken out the 'Flap Motor', and I have been scammed, but I don't know who to go to or what to do to resolve this issue. What do you suggest?
Sorry For the essay
Hi, is the engine in your A3 any similar to the one in the video? On these PD engines it's quite easy to take them out.. Next generation common-rail C engines are a bit more tricky..
WheelsAndMotors yes it’s very similar if not the same 2 litre engine 61 reg . I’m sure the EGR valve and everything is the same as in this video. However I’m not confident enough to attempt to take it out lol !
In 61 plate it might be different. My current car VW Sharan is 61 plate and EGR cooler and valve are one complete piece and located under DPF at the back of the engine (At the back, because unlike A6 where engine is located along the bonet, in Sharan it's across).
I can't prove or disprove what exactly your mechanic has done. I would recommend to go there and have a word about what has been done.
Hi if new EGR need adoption or not?
I replaced EGR on my 2012 VW Sharan recently - it didn't need any adoption.
Do u Heard something about Haas EGR Valve are they good?
@@user-SophiaJ I think HAAS is a good brand (if it's not something trying to be HAAS). I had something from them - oil pressure switch or AC pressure sensor or both... Should be good. But check warranty terms with seller.
Well i did this cleaning this weekend and my intake manifold was literally blocked or clogged with carbon so as my egr, wow fking god i wasnt that horrified for ages
Where did you buy the gasket set from please?
Dealership. They are cheap.
WheelsAndMotors job is done, perfect explanation thanks
Thanks :)
ok, thank you very much, today i took out again the throttle body and I took the egr as well and I cleaned it but that doesn't mean that i fix it , anyway I think that must be replaced but I hope that maybe you are going to give me a way to fix the old one otherwise a new one is £250 not cheap at all , but is original from audi , i found one at eurocarparts for £170 but i don't think that this one does have the same quality as audi one !
thank you again
I spoke to one mechanic (the real one ;) ) today.. Yeah, he said that it's likely EGR valve faulty, but he would need to see it to confirm that. Also he said - it happens to EGR valves, and if it's not too messy and doesn't affect performance, you could drive it for a while till it gets bad..
Talking about quality parts bought from dealership - I don't know, I'm always happy to use GSF of eurocarparts, unless it's something specific that can be bought only from Audi.
Some parts can be considered from second hand, but I'm not sure, if I would want to buy second hand EGR.. Unless it's really cheap and has some warranty and possibility of return for money (not credit note)
Look, I've found one for 157.99:

thank you very much for your time and everything but I took out the egr and I replace it with a new one I bought direct from audi
on internet and on eurocarparts could be found for £160 - £180 , i paid for the original one £240 is not that bad, anyway my audi is from 2008 and the egr is different not the same as audi a6, anyway somehow I am more confident if I know that the part is original
again, thank you very much
and hope you have a video to learn how to change the timing belt as well :)
Here is the video for timing belt:

Is it possible to join the EGR to the Manifold before mounting the Manifold to the engine? This would avoid the danger of breaking EGR bolts.
Could be a good idea, but then you won't be able to access that sneaky-tricky bolt inside intake hole (the one I dug out from carbon in this video) - see on 7:05
Hi there,
My Audi A6 2007 estate has engine management light on and when I drive now it won’t let me go over 40 mph , I put a code reader on and it came up 01826 so I erased the fault on the reader but the light has come on again and won’t let me drive properly again. Could this clean out help me.
Kind regards,
Paul.
P.s. thankyou very much for your upload you are a credit to car engineers ⭐️⭐️⭐️⭐️⭐️
Hi Paul.
This code 01826 points on steering angle sensor. It has nothing to do with the engine. Engine fault codes normally start with "P".
Of course steering angle sensor is something that needs to be sorted out, because it affects your Traction control and ABS and lots of other things.. I'm not sure why it doesn't let you to drive over 40. When initially I had egr problem with my Audi, it didn't show engine management light.
Cleaning EGR won't harm at it's always good, however I don't know what exactly going on with your car.
Try scanning with VCDS? It's more comprehensive, rather than just EML.
WheelsAndMotors ....thankyou for advice,
Kind regards,
Paul
#timeformetogetfleeced 😢
No worries, just find out what's wrong - maybe it's not the end of the world 😉
WheelsAndMotors ...cheers mate, quick update , it’s been checked again with engine running and code reader plugged in and now it’s saying 01200 😤. It’s all bloody fun ain’t it.
Is it comprehensive scanner like VCDS (vag com) or just OBD code reader?
Anyway, where your codes point is like ABS and steering angle sensor, stuff like that.
I'm not professional, so I'm afraid I won't be able to help you.
Hope you get it sorted easy.
My 2005 A6 2.0 Tdi had this done 4 years ago at 80 thousand miles. Its now has 164k and is starting to leak again. Is this normal... any idea what is causing the build up. Also how long does it take to complete the job and approx how much does it cost in euro. Thanks a mil for the upload!
I believe that carbon build up is inevitable, because exhaust gases are dirty and EGR system brings it back to intake. Also on older engines there's always a bit of oil coming from the turbo. But if you have oil leak on the outside - that would be sign of something faulty. In terms of cost - I only bought gaskets. Total cost from dealership about 10 pounds, which would be about 15 euro.
Would a blocked up EGR and throttle body give a check engine light on the dashboard??
On this 2005 Audi, both EGR and flap motor didn't give check engine light when they were faulty, but it did show when someone scanned with VAGcom. Newer cars can show - my 2012 VW Sharan currently has check engine light - P0403 - egr control circuit.
Anyway - on this Audi it's easy accessible to check or clean..
I replaced that pink seal but in the end I realized that in not that is something else
the problem is the egr valve , on this egr valve is a small hole on it ( 2-3 mm diameter )
and the leak comes out from there, what do you think about that, something that I can fix or I need to replace egr valve ?
my car is audi a4 s line 2008
thanks
A hole in EGR valve? How come there is a hole? If you have a damage, I suppose valve need to be replaced..
Could you post an image on my website? Then I can also show to some professionals...
great video thank you
+John Andrews You're welcome :)
How many kilometer's had the engine before replace and clean EGR valve and intake manifold ?
That car was doing lots of miles/kilometers, I don't really know. I suppose it depends on how you drive it. Luckily in this car it's not difficult to take it out and check at any time.
Thanks for your answer! Understoond!
Can you live link for all gaskets please.
Gaskets are not expensive even from a dealership. What I did - just called them and explained what gaskets and where they go - they just got right ones.
After this cleaning proces need doing adaptation egr?
No. Because you fitting same unit back.
Thanks.
Any chance you have bolt diagram for the manifold? Thanks
No. I don't, sorry. I don't even have that car anymore :(
Hi. I have an Audi A4 2.0 tdi 170 bhp. Recently my coil light started flashing on dash board and error message came on it was the motor for intake manifold flap. Happened twice more and all I the space of two days. All error codes have now been erased and car is running better than before. It's been a week and all is good. Is this a sign that my motor for intake manifold flap needs replacing or a good clean would do. Thanks
Is it the same for petroleum 2.0tfsi audi a6 c6 2010
Sorry, I don't know about petroleum...
Hi there I've got fault code 2009 on my a6 avant, engine management light is on and can't get rid of it. Was this what was happening with yours and if so did it clear after the clean down? Thanks
Is it P2009?
WheelsAndMotors yes it is aye
Not sure how to help you with this one Ross. I've looked in the web through my Torque app, looks like it might be pointing onto intake flap motor (throttle body), although if I'm not mistaken it has it's own code. Worth checking anyway. Here's couple links for you.
This is what I found in the web regarding P2009:
www.troublecodes.net/p2codes/p2009/?from=torque
I also have a video about that intake flap, here is the link:
ua-cam.com/video/RwQ1q-EcG58/v-deo.html
Thank you very much mate I'll look into that
what ia the torque in Nm for the bolts?I heard that on th 1.9tdi is 25Nm.
what bolts you mean?
+WheelsAndMotors the bolts from the manifold.I had a problem,I have cleaned the manifold intake,egr and anti-shutter,but I didn't managed to tight the bolts from the manifold and the car started to give white smoke on the exhaust,because the oil that is cooled from the manifold passed the gasket and into my inlet. please tell me is it 22Nm for all manifold bolts? thanks
+unrealistu Just had a look in manual - they are 22Nm
Hi, on german engine 2.0 tdi, like A3, if I blank the egr valve, does the car go in limp mode??
I did it in a ford mondeo 1.8 tdci 2008 and there is no problem to do without consequences.
Hi Sergiu, I don't have and experience of blanking EGR. There are lots of opinions whether do it or not. I think that it certainly keeps intake cleaner. Now I drive 2012 VW Sharan, it has nearly 250.000 miles, has DPF and I didn't have any trouble from EGR yet. Maybe they have learned how build it so it works? :)
I don't think it should go into limp mode, however, as far as I know - some amendments must be done to ECU, because if it doesn't know that EGR is blanked it may calculate wrong air/fuel ratio. But, as I said. I don't have experience - maybe you can just blank it and forget it. Not sure..
what are the 3 gaskets called you need to replace plz?
I bought them in dealership, they are not expensive, not sure if they have specific names - I just explained them where they go - and they sold them to me.
fantastic video :)
Thank you :)
hi! I have a A6 3.0 quattro s line 55 reg, the car is smoking white smoke.i've checked the injectors and it's sayng that they work just fine.can you give me any evidences please.
thanks!
sam radu Does it smell like burning something? Is there a noise from turbo?
I have a p0404 code and limp mode on my a6 c6 2.0tdi. Ive done a carbon clean but still no joy. Should i just replace the whole egr unit as its making some pretty horrible noises. When i clear the codes power comes back but then goes to limp mode again after a short while when the code comes back. Any help would be much appreciated
Did you take it apart like in this video or was it some other cleaning without unbolting stuff? Yeah valve can get faulty too, so if it's clean, but still gives trouble - perhaps you need new one.
WheelsAndMotors not taken apart no... used a mobile carbon clean bloke. The black smoke that came out was biblical! Almost caused the block to lose all visibility so im assuming it was very very clogged up which damaged it
In that particular car EGR is quite easy accessible, maybe it's worth trying to clean it completely to shiny condition (like in the video), see if helps to get rid of the code.. If not, then probably new valve..
mikeyBIA dude, I just got the same. What did you do to fix it? Take out and clean ?
Very good video my friend. It also shows clearly that recycling exaust fumes that contain carbon, is simply bull shit.
Thanks :)
You are great!
Thanks 😎👍
What is the part number of the large gasket? The one with all the holes please
I don't know, I just bought it from dealership, explained where it goes and costed me about 3 pounds. Just had a look on eBay - it's more expensive :) Check this link:

Thank you. I did this today. Load of black soot and crap in there. Used 4 cans of cleaner and still not completely clean. But had to put back together. Will clean it again soon. Great videos by the way. So glad we have the same car
so what kind of the problem come when the AGR valve & inlet manifoold is too dirty ? cause we have VW 1.4 tdi have a( big white smok & a bit engine knock )& cold start all this problem can be cause of that AGR Vave & manifold is dirty?
+wavu shabani Yes, when it's dirty it can cause different problems. The one I had - EGR was clogged up and stuck in position "open" - so exhaust gases were always coming back to cylinders, even when engine was cold and needed more air.
ok thanks a lot man
