Audi A6 2.7 & 3.0 TDi EGR & Intake system cleaning info please...

[Guest 2]

I just thought I could help by sharing my experience. Being a passionate VW owner like yourselves. In my spare time and yes even on vacation I like to see what others are doing with their vdubs. Thanks anyway for the opportunity to share and be helpful thanks and good bye.

If I'm wrong then please accept my apologies.

It's just that your first two posts were recommending a product and your location didn't match your IP address and most spam accounts are like this.

Another query six_or_out & sparker as I'm trying to understand why my manifold/tba would be so coked up...

So six_or_out as you've been on "Long life" servicing as well that throws that out the mix but my car even if same year as yours half the mileage roughly...

So does this further reinforce that "Long life"=motorway driving/higher miles a year and "Interval"=local/lower miles a year...
My injectors were the very first revision until a month ago (059 130 277 S) now are 059 130 277 BD... Link:- A6/C6 injector PROBLEM - Replacement/refurbished injectors possible?

What are yours? have you had replacement ever?

Hi Gup,

Still on the original injectors, I don't know what the part numbers are. I can check once the weather clears up .

Only one intake manifold was replaced in 2009, along with 2 glow plugs. The other 4 are still the original ones as far as I'm aware. I use shell V-Power diesel most of the time or regular diesel with a shot of Redex if V-Power isn't available. I don't know if that makes any difference....

Six.

Cheers guys for info ... I think whatever's caused the carbon I won't get to the bottom of it ...

Since owning I've used V-power/ESSO supreme diesel... injector cleaner was ran several times before injector change to new rev...

The car has had two oil changes in 10k miles under my ownership... last nite ordered more as I never changed oil after injector change... I was real careful not to contaminate engine when doing the change...

Once intake/EGR/glowplugs done will change oil... just ordered bits for the EGR cleanup as well... will also do new seals from Audi...

I can officially state that using Liqui Moly Diesel Clean & Boost

has made my engine run much smoother. The rev fluctuation has mostly disappeared. I did use a huge lot more than what they tell you to use. I'm going to change the fuel filter in the next few days.
I still can't get to the bottom of those revs jumping up and down while driving. I've even noticed since yesterday that my gearbox has been very clucky when changing into 3rd from 4th and into 5th from 4th. Try giving yours a bit of liqui moly diesel clean & boost and see what happens.

Will do mate ...

Ok peeps ...

Earlier this week the spline bits came to allow dismantling of the EGR system further... but I've also been shopping for other parts ...



So in above the big rectangle ports are what meets the EGR cooler... the round section is the straight through when EGR cooler not being used... the two pipes top and bottom are coolant connections to cool this module and EGR as well ... we can also see the vacuum unit at top and its default position and of the butterfly in the straight through section...

Next SRT88 has kindly given be these pictures, so thanks mate ...

Above photos are form a VW Phaeton Feb 2007 3.0TDI mileage unknown...

I've also been scouring ebay/forums for other images of manifolds and most are a little more coated than above but yet to see some like mine ...

I've even seen some pics of same part no manifolds as mine and not the same lava like coating ...

God knows what gone on with my cars manifolds ...

The EGR valve is here now ...



Now waiting on some inlet manifolds ...

Nice n' shiny :-) good luck with the new part.

this is awesome info man - thanks for taking the time to write it all up! I'm about to tackle my EGR and carbon on my B7 2.7 V6 TDi and this is really useful info and pic!

hope all works out good for you! I'll be keeping an eye on this!

Thank you for viewing ... Thank you acknowledging how viewing the videos/photos it is helping you ...

As owners we don't see these things... by viewing them we can make better judgements on what we can do/get done...

Sorry about slow progress but weather been hindering me ...

Many a time I have thought I'll leave airing my gripes/issues as:-

i) may make selling my car hard...

ii) very time consuming to take photos/videos and editing/uploading...

iii) if I was not taking the media shots it would mean I finish a job quicker as well...

BUT I find it hard sometimes to visualise stuff from text... I read threads and lack of detail or media make them hard to follow to do yourself/understand...

I know it may sound selfish but I have given alot vs taking from this forum... but soon I must just stop posting ...

However much I dress it up this car has been soul destroying further exaggerated by the poor detail of work by garages I've been to...

When you employ profesionals who do things for a living/day in day out you expect them to be better than amateurs like me!

I will be finishing the threads I've started before I become a lurker...

Crazy - I understand your frustration as all you did was post some helpful info with a link to a product you felt may be of use in this situation, you clearly felt you were jumped on immediately. Its unlike Chris as far as I know and perhaps we've been having spam issues I'm not aware of.
Don't let this skew your view of an otherwise pretty good forum, hopefully you continue to enjoy the site

Wow Gup - you make it sound like you're leaving the forum almost......why?

Please believe me when I say that I and many many others really appreciate your lengthy indepth posts usually c/w many pictures & or videos clearly showing the process involved.
Its posts like these that help to make this and other forums and the posts that members need to help them to resolve their issues with their vehicles. Posts with 28 lines of unbroken text explaining do this, then do that, unbolt this and remove that, really don't help anywhere near as much.

You have probably given as much if not way more than most here and we need more members like you, not less!

I for one sincerely hope you continue on here and post as you have done in the past, your posts have been an invaluable source of information for many. I've been fortunate enough to share a few posts / comments back n forth and count you as a friend and one I'm glad to know.

Thanks Gup
