Hi.
Went out to my 2004 A6 1.9Tdi Multitronic at lunchtime, which started normally but would not rev past 1500 rpm.
I was on the verge of phoning the AA (my Audi dealer said they could not look at it for a week) and drove it down the road upon which it cleared and seems to drive normally.
If I am being picky I would say that the engine does not seem to respond quickly to the throttle as normal.
Any ideas?
