Hi At the risk of sounding like a complete novice can anyone tell me if this is normal. I have just bought an Audi TT (225) Coupe. It is a 2000 W reg car with 23,000 miles on the clock. When I put my foot on the accelerator to accelerate and then change my mind and lift off I can hear quite a lot of Turbo. Likewise when I accelerate hard and then change up a gear. Is this normal?
