As above- My 05 sportback loses power/cuts out (has stalled twice) occasionally- the common denominator seems to be when I go over bumps/pothole infused roads. Doesn't happen every time, but a speedbump/bump/pothole is always the catalyst for it! Any thoughts? Have scanned via vcds but no fault codes relating to the prob (one for a electric window, one for aircon I already knew about). Any thoughts??
