hi people
i have recently bought an a6 2.7bi tubrbo quattro and in the past couple of days have noticed a substancial lack of power in the rev range above 3.5 k it is fine below this within reason it just lacks the push from the turbo above 3.5 i haven't had any noise or vibration and the engine still sounds perfect
the only clue i have is a vag com showed that both banks are running lean would this cause the loss of power as the engine trys to protect itself?
please help me and my local garage are very stuck and dont want to take it to a stealer
