b****r,still not fixed!
Have been in to see the dealer this morning and had a chat with the mechanic(very nice guy with lots of Audi experience).
They tried replacing the egr valve but with no joy.
As it stands now the dash is out but the noise is still there.
I have left it with them for as long as it takes and they have just lent me a brand new A4 2.0TDI Advant(very nice, but 6 gears????)
If anyone has any other ideas i would(and the dealer)be pleased to here them!
Thanks Dorian[24]
 
OK IT'S FIXED AT LAST !!!
The dealer(bless there cotton socks),having tried just about everything,got in touch with Audi uk who in turn got in touch with Audi AG.
Yes, they had come accross this before and there is a modification kit to solve the problem.
The kit consists of modified fuel supply and return pipes.
It appeares that the noise was actualy the fuel resonating inside the pipes under specific conditions ie;when cold(thicker fuel) and when the high pressure pump was working at its maximum.
The noise was also being transmitted through the body bacause the pipes run through the car,which was making the noise both VERY loud and VERY difficult to find.
Anyway im a happy chap because it has transformed the car, and if anyone requires more info please get in touch.
Thanks for all the help.
