How to replace and clean EGR valve and intake manifold on 2.0 tdi Audi A6 (C6 4F)

[@chrisfenton9425]

I cleaned my EGR valve today. What a difference to the performance! Could not have done it without this video. Thank you!

[@wawayltd]

You're very welcome 👍 Glad if it helps. Happy New year! 🎉

[@marceljiboc8144]

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

[@wawayltd]

Glad if it helps 😎👍

[@NHBarca]

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!

[@wawayltd]

Thanks :) Pleasure to see such appreciation :)

[@duoanghelos]

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 :)

[@wawayltd]

You're very welcome 😊👍

[@eddiehakiza4050]

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.

[@wawayltd]

You're very welcome Eddie 👍

[@ZakhariDarksorrow]

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!

[@wawayltd]

Thank you :)

Wow, I can help real mechanic :) That's a honour! Thanks Martin :)

[@stephenp3300]

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!

[@tekuzman]

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.

[@davego5644]

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 ;-)

[@wawayltd]

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 😊👍

[@munsterfloyd]

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.

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.

Great video, how many miles has the car done ? Also try cleaning the manifold with foaming oven cleaner, it works great.

[@tekuzman]

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.

[@wawayltd]

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.

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

[@wawayltd]

There are ways to do so, some kits are sold. Have a look here on KZbin, but.. I don't know why - it is pretty simple to take it out and see what's going on for yourself ;)

[@wolar1000]

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?

[@wawayltd]

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?

[@samradu8525]

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

Head gasget

[@gmg444]

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!

[@wawayltd]

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.

[@steveo5701]

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

[@KK-pw2dt]

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

[@wawayltd]

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 :)

[@dragogrbic9255]

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

[@rodneybrown8620]

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]

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?

[@rodneybrown8620]

@@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.

[@wawayltd]

@@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.

[@zagroszabihi2791]

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?

[@wawayltd]

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.

[@frankw9836]

I have problem on my 2008 Audi A6 over and over again P0088 driving Home in Limp Mode , ordered the FUEL RAIL HIGH PRESSURE SENSOR, EGR VALVE & new glow plugs on eBay . No Idea if i actually needed those but after watching some Videos, this seems to be the problem regarding P0088. Get my Mechanic to fit it and hope the Problem will be gone !!

[@wawayltd]

Yeah, it's a very important skill of a mechanic to determine what exactly is wrong with the car, instead of throwing money on unnecessary swapping parts.

[@frankw9836]

[@EdwardTiberius2011]

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

[@wawayltd]

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...

[@wawayltd]

Rough idle is a common problem with this car... Unfortunately, I don't know - would love to find out myself.

[@cbreslin91]

Did you ever get these problems sorted? I have the exact same problems, hoping the EGR clean fixed them?

[@trevorroberts5839]

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

[@wawayltd]

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?

[@mawganbrev3525]

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??

[@wawayltd]

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

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.

[@tomscott4699]

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?

[@wawayltd]

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.

[@steve323f]

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.

[@wawayltd]

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..

[@paulrossiter9567]

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 ⭐️⭐️⭐️⭐️⭐️

[@wawayltd]

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.

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.

[@wawayltd]

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

[@RR-oh1hj]

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

[@wawayltd]

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..

[@RR-oh1hj]

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 !

[@wawayltd]

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.

[@leolammas7940]

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.

[@wawayltd]

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, 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

[@wawayltd]

Lukasz Sieniuc Hi, I also have seen some videos, but never tried to do it myself.. So I can't say much...

[@sy7zx]

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.

[@wawayltd]

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..

[@everlast2658]

thanks for your help, can theegr be blanked on this engine with throttle body ?

[@wawayltd]

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 :)

[@jankivila8007]

What was the problem? Idel was rough or what? What was the reason for the cleaning

[@wawayltd]

This time I have done just for simply cleaning. Before that it had misfire when starting cold. EGR was stuck in position "open".

[@MrWavu]

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?

[@wawayltd]

+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.

[@MrWavu]

ok thanks a lot man

[@nikolcenecovski6739]

I have problem with first starting audi a6 c6 2.0 140hp. First start crank long and then start engine. Second start is ok. If i leave 6-7 hours again first starting is long. Fuel pump and heaters is new. Whats the problem?

[@wawayltd]

Don't know... Glow plugs?

[@jaggass]

How much better did it run after this?

[@wawayltd]

+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.

[@Gq_Lorries]

If I blank off the EGR will it stop the blockage?

[@mrkornelyuz]

Cleaned it but still doesn't work will i need a new one then?

[@wawayltd]

Possibly. Does it give any fault codes?

[@jakemybigblackdog]

Would a blocked up EGR and throttle body give a check engine light on the dashboard??

[@wawayltd]

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..

[@rosshart6540]

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

[@wawayltd]

Is it P2009?

[@rosshart6540]

WheelsAndMotors yes it is aye

[@wawayltd]

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: kzbin.info/www/bejne/iKi0YqRjesh6a5o

Thank you very much mate I'll look into that

[@everlast2658]

hi how would i remove the servo on the manifold that operates the flaps, as the manifold needs a good clean

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.

[@user-GTK9]

[@kaanerdem2822]

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

[@mikeyBIA]

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

[@wawayltd]

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.

[@mikeyBIA]

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

[@wawayltd]

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..

[@adamfergusson1]

mikeyBIA dude, I just got the same. What did you do to fix it? Take out and clean ?

[@ukkomies100]

What do i gain from doing this. I mean would i be better of leaving it as it is and just disconnecting and blocking the vaccuum diaphram hose from the exhaust side egr valve so that ecu has no idea of my shenanigans

[@wawayltd]

There are lots of ways to disable EGR, and lots of arguing on forums whether it should or shouldn't be done.. In my personal opinion, I think it's there for a reason and I would keep it working.

@@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.

[@wawayltd]

@@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..

hi mate, grate vids as always, was wondering if you have one where it shows how to change Boost Pressure Control Valve N75? thanks

[@wawayltd]

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

[@mushy_GLX]

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😁) 

[@wawayltd]

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..

[@MegaClashcityrocker]

Thanks for this. What are the typical symptoms of a blocked EGR? I have a 2.0 TDI in my 2007 A4 that feels lumpy when idling. Could this be a blocked EGR? What sort of time to reserve to do this job?

[@wawayltd]

I would say, if EGR valve gets stuck, performance depends on which position it's getting stuck on. You know, EGR is 'emission gas recirculation' - it sends part of exhaust gases back to cylinders for re-burn. Gases get cooled in EGR cooIer (see video at 0:39 ), and then pipe goes to the valve, which is depending on engine demand is closed or open. I had my valve stuck in position 'open', so even when engine needed more air, it still was suffocating in exhaust gases. It was misfiring (not only when idling) and stalling. EGR system is needed only for cleaner emissions - it doesn't improve performance. I've heard of some people who block it on purpose - all exhaust gases go away without re-circulation.. Also here on KZbin and at my website - lot of people with Audis complain about rough idle. Recently I started getting it. I suspect, it could be bad engine mounts, because I'm getting like a resonance at idle, 1600 and 2400 rpm.. When I'll have a bit more time and money, I'll have a look in this problem. Stay in touch, would love to know how you getting on :)

[@the_chris]

This was the first sign I saw that my EGR was getting blocked. On these engines, BEFORE the valve gets stuck, you get a specific list of symptoms: * Rough idle when warming up. Specifically, the engine is fine cold, but rough between first being turned on, then warm. The roughness goes away. * Smell of smoke coming from the exhaust Now, rough idle can also be a timing belt issue, which is also common, but is likely EGR related. Note that these symptoms will go away when the valve gets stuck, as the comment above states, which will happen eventually if you don't clean it.
