Hi all, after 9months and 31,000miles looks like my car had enough of me and tried to commit suicide! Started calmly enough, earlier in the day, accelerating, the car hesitated around 2,400rpm, with about 10-20secs of heavy white smoke, was fine after that, no warning lights or anything, but called Audi and booked it in to be looked at. Had an appointment, left and drove off, about an hour later, at traffic lights, the engine just went haywire, all the way to 6,000rpm (the max for about 4 secs, was like a TV special effect with all the white smoke), it then went back to idle for 5 secs then up to 6,000rpm again, with lots of white smoke! Again no engine warning lights or anything. Obviously pulled to the side of the road. RAC guy came along and switched on the engine, and was fine for 20secs, when fault re-occured, he jumped so far! Had no idea what the problem was but thought it could be the throttle sensor Anyway, car is now with Audi, though on the plus side,getting an A6 tiptronic in replacement as courtesy car!
