Hi, I have a '99 A6 which runs fine until above 30mph. When in gear and doing above 30 it is fine but if i take it out of gear or dip the clutch for more than approx. 2 seconds the revs drop smoothly down to 0 and obviously everything stops!!.
Car has been to garage and nothing is showing when plugged in!
Garage reckon it could be the accelarator and want £300 to replace! If this is prob. then why only above 30mph?
Any ideas??
