Faults:

Instruments lights always breaking, power steering tubes blow up, drivers window starting to fail, Audi alarm just died as the central locking, suspension arms (new) with a lot of noise.

General Comments:

A sporty sedan, but very uncomfortable for the passengers (at least with leather seats).

The electrics must by made in Italy, because something is always failing.

Front suspension always with some noises, even with new arms (not Audi).

It's a nightmare to maintain : everything is expensive (about 30% more than other brands).

One thing I have to say: it never stopped on the road.

About 200km/h max speed and 10/12 l/100k. It's always thirsty.

In summary: never again will I buy an Audi just because of maintenance prices. Too expensive and always something not working.

My Citroen was better in every way: cheaper to buy, better to maintain, more comfortable, faster in the city and motorway, and much more comfortable.

Actually own a Laguna 1.9 DTi from 99, and it's far away better than my A4. Maybe I was unlucky, but this is what I think of it.
