Last year the Turbo went in my Audi A4, I brought it to Audi West London and got it changed for around £1,200 stg. I had a lot of hassel with them first time around as they managed to damaged the wing on my car and it took them 5 weeks to get my car sorted.. anyway... before Christmas I noticed my turbo started to act up and whine in the morning when you first start the car, when you drive down the road it smokes like a b1tch, to the point where you can't actually see the car. I brought the car back to Audi on the 9th of November (as it is under a 3 year warranty). I am still driving their Courtesy car nearly three months later. They are impossible to deal with. They are saying that there is oil in the exhaust system and it needs changing and I had too much oil in the engine. I had the car checked by a mechanic before I brought it to them and he said that a seal was gone in the Turbo. I suggested that I get in an AA mechanic to their workshop to check it over to try and resolve this issue. Its like banging my head against a brick wall.
Anyone got any suggestions ?

Cheers
