I had this on my allroad, i replaced the ecu and turbo, no help though! in the end i sold it to a garage, mugs.

ECU thinks turbo pressure may have gone to high. Car will feel gutless. Try replacing all the litte vacuum hoses. If not that try the pressure sensor. One simple test is to get someone to gently rev engine while you push, pull and twist all the little vacuum pipes. You will hear the engine pick up if you find a dodgy pipe.
