    Are you pulling away in second? No offense meant but if you labour the engine it tries to bring the revs up to stop you, I get a surge now and again when the car is labouring.

    That's a boost leak. Could be the DV if you are running a std plastic one. Clear the code and see of it comes back.

    Did you ever sort this problem out? I have this code come up. Only seems to happen if the outside temp is 5 degrees or less. Car goes into limp mode and runs on actuator pressure only. Stupid thing is, I can restart the car seconds after it happens and all is good... I had this happen when we had the snow etc and then it went once the weather became milder. Had a frost this morning (2 deg outside temp) and its back!!!

    I have checked vac and boost pipes and have a Forge DV, sticky N249 maybe? I have also cleaned the throttle body and did a TB reset in VAGCOM.

    Any suggestions gratefully received
