The e-golf was in motion on a pedestrian road, the vehicle stopped without warning. then, a message displayed stating something like "error: electrical system." the car would not move at all. the car was turned off and on again, yet nothing happened; it could not be restarted, the windows wouldn't roll down, and the car had to then be pushed to the side of the road in "neutral" for safety. the cause of this problem was unknown. roadside assistance was called and the car was towed to the local volkswagen dealership/service center. the service people at the dealership did not know what the problem was and they called volkswagen for a specialist to come out. a specialist came about a week later and the specialist also was unable to determine the problem, however, a week later the dealership service center concluded that the problem was the air conditioner compressor via volkswagen (the dealership service center claims that volkswagen called them and told them that).
