I just bought a very nice K 92 9000 CS 2.0 Turbo S. Its only done 126k, has full sh and runs very nicely except that the turbo does not seem to be boosting power. I noticed this on the test drive but the car was so sound otherwise I just made a daft offer and bought it. It runs fine and accelerates reasonably well, quite torquey, but just seems to lack that turbo push where I think you should feel it ....maybe from 3000rpm or so. No obvious signs in the engine bay. Just wondered if this is something anyone has experience of and hopefully an easy fix ?
