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! 🎉
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 👍
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!
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 :)
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 😎👍
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 :)
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😃
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!
if i ever buy an a6 i will surely follow your channel!
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.
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 👍
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?
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 😊👍
Thank you very much you been a massive help with all your Audi A6 C6 videos.
You're very welcome :)
These videos are so helpful thanks for the good work!!
You're welcome :)
An excellent video thanks for this will use it to service my Seat Leon. Keep these videos coming really good.
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.
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
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?
thanks for the knowledge, a good old street mechanic
You're welcome :)
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 🤓👍
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
Thanks mate can’t wait to start mine tomorrow
It's pretty easy with this car, just a bit messy 😏
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..
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 😊👍
Great video, how many miles has the car done ? Also try cleaning the manifold with foaming oven cleaner, it works great.
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
Very helpful video! Many thanks.
You're welcome 😊👍
Thanks for the sharing, it's very helpful to me.
You're very welcome, Richard :)
Thank you for this video. Very helpful video
You're very welcome 👍
you are a star bro i have same car and luv your vids
Thanks Mawgan :)
Thankyou.
Fantastic video
Thanks
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.
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.
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.
fantastic video :)
Thank you :)
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 👍thank you
Thanks 🙂
Good work bro!👌👌👌
Thanks 👍
Good job buddy
Thanks 👍
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/
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
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.
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.
great video thank you
+John Andrews You're welcome :)
I have problem whith my Audi A6 C6.
The first start engine when the temperature outside is 3, 4 °C or more is hard and long. But when the temperature is -7, -10...engine starting currently.what could be the problem?
No idea... Battery?
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...
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 TH-cam, but.. I don't know why - it is pretty simple to take it out and see what's going on for yourself ;)
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 :)
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, 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..
Good video
Thanks 😊👍
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.
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 :)
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 :)
i have a a6 2.0 tdi blb and the car judders/vibrate only on idle when the coolant temp is at 90 C. any ideas?
My Audi was also blb, and I wish I knew what causes this judder on idle. Quite a few people complain about it here on my TH-cam channel and my website.
Before I got rid of my Audi about year ago, I also started having that judder on idle now and then, especially after motorway run. Then oil pump went, it was coming to the end of taxi licensing age anyway, so instead of fixing, I got rid of it. She's done 409k miles :) There is also opinion that engine mounts may go bad, and probably it catches resonance at certain revs. Like I had judder at 1600 revs in neutral.
Thanks!
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?
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!
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. Guess I'll be off to the dealer's!
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...
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.
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.
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
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..
will be much simple to do now in the vw jetta
which car?
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
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 :)
have same engine, can i block the egr just putting a blanking plate?
Ri Mas I've heard of people doing that, but I think you would need to tweak ECU as well rather than just blanking, so it doesn't give you an error. But I've never done it myself, so I don't know for sure...
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:

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?
Don't know... Glow plugs?
would this be the same for a Audi a3 bkd 140 bhp model?
If it looks the same - could be the same or similar.
Can my problem with heater blower be anything to do with centre consol ,I have missing light on 4 buttons from radio down ,and no lights on big round dial ,bed sometime it work and sometimes not ,any help would be very good as I don’t have car manual, A6 HD06 SWW ,2.0 Diesel.many thanks
Probably can be.. Unfortunately, I don't have experience with electronics of climate control..
Did you change pollen filter?
Not yet on order
Have you ever had centre console off ?
@@bernardjohnston819 I have video, where I take MMI apart, and I have one where I take climate control unit out, but I don't think I would be able to fix electrics of that..
P.S. Start with pollen/cabin filter - it needs to be done anyway.
Thank you I will
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..
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 🙄
You are great!
Thanks 😎👍
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
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
has anyone tried water decarbonizer?
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?
Is it the same for petroleum 2.0tfsi audi a6 c6 2010
Sorry, I don't know about petroleum...
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.
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, 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
hi there mate i have an audi a6 my audi is vibrating on idle and when in drive its fine ive been told its the duall mass but my mate has realised as the rpm is just less then 1cm below the 1000rpm when he pressed the accelerator to 1000rpm the vibation has gone any help i could get from you it would be very apprichiated
1cm bellow 1000rpm? Is it like 600? 600 is definitely too low - it should be about 900 normally... Does it get misfire? Do you get any trouble while driving? I don't know, mate -it could be anything.. egr, throttle body (I have a videos for those)
It can be computer that controls injection at idle. . You need to find professional who can have a good look at it, or for start search google for something like "2.0 tdi low revs at idle"

WheelsAndMotors do you think it could be with egr valve to do with or throttle body causing the idling?
kristijansuzana Yes EGR valve and throttle body can affect idle, and as you can see from the video - it's not a rocket science to take them out to have a look.
When they out - EGR valve must be shut, throttle body must be open. They both have to not damaged and open and close neat :)
Here's link to the video about throttle body:
How to replace intake manifold flap motor, aka "Throttle body valve" on 2.0 tdi engine (Audi A6)
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
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.
i keep getting a fault code p0101 have put a new maf on the car and still get it any help would be great as i got no clue?
Maybe there's an air leak somewhere in intake system?
@@wawayltd i will try and look and see if i can find 1 ty]
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?
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:

Thank you very much mate I'll look into that
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 ?
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 👍
Any chance you have bolt diagram for the manifold? Thanks
No. I don't, sorry. I don't even have that car anymore :(
bro I have 2.0tdi 170ps, have had dpf&egr off,,,after some time the car started loosing power on low rpm is dead and theres a lot I mean a lot of black smoke behind, went to the servise and they said me that it's not a bad turbo but it's caused by the small egr valve[the one where exhaust gases come off], could it be from it or ?
+dini muaremi I didn't know there is another valve.. :) Can't say much about it...
on the main one wright ,theres a small valve upper ? [i dont know how to send a picture to you :( ]
Come to my website, you can include images into posts. www.WheelsAndMotors.com
is the connection to the EGR also the egr sensor ?
Probably not. That connection is to control EGR.
hello again
I tried to post something on you page I don't know why I can;t maybe I don't know how
anyway yesterday I came back from shopping and I went indoors then because the weather was nice I was thinking to wash the car and when I opened the door I realised that one of my tyres is flat because i heard like the air is blowing out from somewhere
I check the tyres back one then front one and then I realised that is not the tyres, all this air came out from radiator but as I told you with high pressure, I took out that plastic from the top of the radiator and I checked by hand and the thing is the radiator is fine but all that air came out from that sensor or whatever is called and I was thinking that maybe you know wat is it and why is doing that I fond again some photo on e bay and you will see on the top right there is like a sensor and from there all this air came out
do you have any Idea why ? I check the liquid in that bowl and is fine I have no leaking .
please let me know what do you think
thanks !

If you are not loosing coolant, maybe that sensor (and coolant system) is allright... Because, if you have a crack in that area, you would be loosing coolant. I had a whistle there, when my intercooler cracked. Check, maybe it's not radiator/sensor - maybe it's booster pipe/intercooler?
is not on that side where is the ventilator is the second picture somewhere almost on the top on the right side
Where is the connection to the Audi A6 2006 Quattro computer, and how to properly clean the pins??
Sorry Akuma, I never had Quattro..
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:

can you write the code of the gaskets . or place who i can find it online o have a problem with my trothle body it is on 94.9% all of the time :s . and go to 100%
+Alen Osmanovic I don't know codes for gaskets, when I bought them from dealership, I just explained where they should go, and they sold me correct ones. What is wrong with your throttle body? I know it supposed to be fully open all the time, but it doesn't normally show 100%. All my cars (diesel), showed about that number. When I get to my car, I let you know what it says..
+WheelsAndMotors the bigest problem is that. i have change it one time . and first drive qith the new was all normal :s and after stock on 94.9 :s :(
+Alen Osmanovic Maybe there's something I don't understand.. Why 94.9 is a problem?
