Local Audi dealer told me my poor starting problem would be cured by a £1200 service (car was only 4 years old at the time). AA fixed the problem in 2 mins flat (it was fuel pump related and needed a new relay only).
Have had an idling problem for a while which the garage have not yet totally cured. Original problem was that the idling RPM would climb to 2600-3000. Now they have worked on it, it just dies on me at the traffic lights!
Car has over 162K miles on it now and is starting to sound a bit tappity. It burns no oil and still gives me 34-36 to the gallon.
Would love a Coupe Quattro(old shape) with nil miles on it!
Has been an absolute pleasure to own.
Idle - sounds like a simple case of mixture and idle. I had the same problem with my GT Coupe 2.0 1984 with 208 Km on the clock.
Believe it or not, a chap in a wrecking yard told me this and fixed my problem.
Needs a clever allen key, apparently don't apply any pressure to the key when turning. Put the lights on to to simulate a load on the engine when re-setting the idle.
Trust this may assist.
