How to tell if turbos need replacing in as S4?

Discussion in 'A4/S4 forum(B5 Chassis)' started by imported_druggie, Oct 4, 2004.

  1. Appart from the tell tale noisy turbo bearings , how else can you tell if the turbos are faulty or need replacing?
    What checks can the workshops perform to tell one way or the other?

  3. if the car is not holding boost... boost gauge best way to tell that... if it holds boost evenly through the revs then should be fine.
