I need help guys!!! Last night I was at the end of a run from Chelmsford to Heathrow (about 75 miles), and as I came off the M4, my engine just lost power! No warning lights or noises. The car came to a halt but would not restart. I got the RAC out but they could not connect or read anything from the car using their diagnostics which he said could be caused by the ECU packing up, apart from that he could no fault with it. The RAC got me home and say they will come back to tow me to a garage. I dont know where to start, do I go to Audi and get shafted of what? Any help would be greatly appreciated.
