Diagnosed my problem .........
Not the EGR valve - mine is a blocker crankcase breather again. I won't be paying Audi to do it again - but I will try the newer part. Do you think this is a job I could get a competent friend with tools to help with - or are there specific tools neeeded ?
Also - as a guide how long would this take so I have a clue as to what my local garage should charge...
white blue smoke after mechanic changed breather pipes
Hi I am so happy to read this.I just had 2 new breather pipes changed and when I picked up my car there was smoke pouring out of the exhaust.

i am guessing that he didnt install the pipes correctly or I need an Oil Mist Filter.
maybe i will go to the dealer and get this filter
if anyone has any comments, just let me know
Clogged crank case breather
I believe I had the dreaded oil breather problem on my A6 2.5 TDi that had done 220K miles.
It was OK on start-up but once warm (after about 10 mins) left a cloud of white smoke whenever I stopped. It frightened the life out of other road users when I had to stop in slow moving / stopped traffic. It continued to perform OK.
My independant Audi mechanic said it was the valve stem seals gone due to the high mileage. As the car was getting tatty I sold it for spares or repair on ebay.
Whilst selling it I researched further & felt sure it was the blocked breather. This pressurises the crank case & forces oil out through the weakest points.
DO take the oil filler cap off & if there is pressure pop / noise then I would definately say its the breather. There is an excellent account of how to replace it (on this forum somewhere I believe) - but I donr have the computer to hand that I saved it as a favourite.
The part costs about £35 from Audi & you should buy the later one - which is updated. I now have an 03 2.5 TDI & bought a filter straight away - which is the later one.
The job involves removing the fuel pipes & lots of other bits of plumbing & takes about 3 hours - if I remember the account given.
Hopefully someone else on here will point you in the direction of the link.
Let us know how you got on!
Good luck - John C
