    LOL... as you know Chris... I test drove other cars before getting chain rattle done... and even now...

    Quattro + 3.0TDi + Tip = only thing IMO is better S6>>RS6

    Now I really know what to look for IMO... I just wish I had this knowledge when buying Zesty the A6

    So not only will I view car... I will diag the nuts off it... then maybe borrow the ramp from selling garage and show them what a multipoint check look like...

    I know there's nothing funny about your problems but this so made me laugh! As they say though , many a true word spoken in just.

    But another thing I've noticed whilst having my head under the engine so much is...

    Production date on sticker on the engine 25/02/2005 located on left area on engine between air intake on turbo and swirl motor...



    So when buying a car you can check on site... for example look at the timing scales...

    So my car first reg xx/09/2005, but production date of car from Audi customer care 07/03/2005, now engine date is 25/02/05...

    To really miss the production issues I've had or to get a better A6 in the 2.7 / 3.0 my view is 07/57 is what you need... in the prefacelift...

    I've posted some stuff here as well... Link:- Buying an A6 Avant - any watchouts?

    SO the EGR valve was left... A8 post helpful info Link:- Post 115

    I still may buy/get a vacuum test done on EGR valve but I think it is OK...

    My method of viewing was... so red box is the EGR valve which allow EGR gas flow to throttle adapter/intake...



    The green box is the solenoid which control actuation of EGR cooling flap... this unclips from bracket by pushing downwards... and when moved aside reveals a viewing hole/air escape... the yellow box on below image...



    Now what could I see?

    When MAF connected with EGR system running, car was idling... I saw EGR valve shaft move upwards on start up... a orange ring was viewable... and a thinner stem further down from that...

    I then disconnected MAF... whilst engine still running... so EGR system would switch off... I saw EGR valve shaft move downwards... the thin stem went down then orange section went past... then fatter section in viewing hole...

    The action was smooth when EGR valve shaft moving up/down... IMO holding vacuum...

    Web pages I viewed

    Link 1:- How Does an EGR Valve Work

    Link 2:- VW and Audi TDI EGR system FAQ

    Some of the info in Link:- Post 110 is from the EU5 3.0 TDi SSP (the face lift A6 09-11) Link:- EU5 3.0TDi SSP , other SSP's studied Link:- SSP 350 and Link:- SSP 325

    Here is PDF of MVB 7 10 18 LinK:- Attachment 18368 if you could have a view A8...

    This morning Zesty the A6 was dropped off at Audi dealer for diags and software update...

    I can't help but feel they may not do an update... but ahh well... see what happens...

    The service advisor was quite shocked when he saw how car start with MAF connected and without...

    I just wonder what the bill is gonna be... as when service advisor got me to sign the paper... he said it will be per hour charge for diags
