Hi, I have an almost identical problem, On a couple of occasions this winter, when it was very cold and damp, I started the galaxy 02 115 44k and drove off hard, this resulted in the car going into a "limp home mode" until the ignition was reset! The car drives perfectly o.k at other times. I have followed a number of forums but no one else has had this issue until now. Fraud have told me that it is the MAF but i am not so sure! Hooked up vag-com and it reports an overboost condition. My worst fears are that it is the variable vane in the turbo sticking. pikey :P
