Nothing major, but stupid, annoying things.
Fuel gauge intermittent;
Headlight adjuster fell apart;
Diesel heater plugs system intermittent;
accelerator pedal fell apart.
Generally an excellent car. Comfortable, secure and very good on fuel (42+mpg consistently) but:-
(a) to correct even the simplest thing Audi will only sell whole units at exorbitant price.
(b) My experience of 2 major Audi dealers is bad. Usurous prices and attempts to "blind you with B-S".
Couldn't agree more!
The conclusion would be:
Great car hampered by a network of dodgy dealers/services.
Have an A6 Quattro; brought it working to service, got back a death trap !
