I have had my car just over a month, and since i bought it from an Audi Garage it has made an odd noise, the only way i can describe it is when i change gear at about 2000rpm it sounds like i have a turkey under the bonnet!. I took into Audi who confirmed that the turbo was broken and i will have to have a new one fitted. This is a suprise considering the car has only covered 30k. I will have to wait a week for a new one, and they have said my car is OK to drive is this true? Also should this car have been sold to me with this fault?. I didn't take it in at first as i thought it was a general diesel car noise. Hope this isn't the sign of things to come!
