Recently had a scary problem whilst on the Autostrada in Italy, went to overtake a truck at around 70mph when there was a thump from the transmission and it jumped out of gear, it would not re engage and was just like a manual car with a clutch gone, Engine light came on and coasted to a services about 5km further on at 30 mph with a very slushy transmission. This incident was preceded by the box jamming in gear whilst traversing a roundabout, I could only get it to change once I had restarted the engine. Happened twice and now nervous about the car, transported to the dealership but they found nothing wrong with it, the engine light had gone out after a wait of 3 hours so no diagnostics obtained. Has anyone else had this problem and is there a fix? The car has only done 30000 miles so not impressed. It was a hot day and I can only think this was an overheat issue?
