I have a q2 sport and it's a pain in the ass! Every so often when slowing down coming to junction or turning, the engine will shut off and a message will pop up saying "start/stop deactivated please turn on engine manually" and I have to restart engine. Sometimes it will just turn on and I can keep driving other times itll fully conk out and takes a few times to restart. I know how stop/start works- it activates when your at a complete stop- but this happens while the car is moving and has happened at 30 mph... taken back to audi and they said they cant find any faults? Any ideas guys, I dont feel safe driving it but audi arent listening?
