Boss had one, horrible horrible car.

Full of electrical faults and ECU problems, it was brand new, the dealers couldn't give a toss after they sold it to him. They were so naffed off with him in the end that they swapped it for another 2 months later.

Then that started with a similar ECU fault so he drove it in to them chucked the keys at them and walked over to the BMW garage and bought a new M3. He told them to invoice the Audi garage for it....... and they did.

Thats my only experience sorry. But since then I have noticed you do see a lot by the side of the roads broken down or on the back of recovery trucks etc
