Vauxhall Movano crank but no start, no communication with engine ecu

This video shows a Vauxhall Movano that has no communication with the engine management ecu. A lit of people believe that all a technican does is plug a computer & it tells you what's wrong with the vehicle. What happens when the computer can't talk to the vehicle?? That's when you need a skilled, trained tech. It's as much about the skill & method as it is the tools used #vauxhall #movano #amsmobileuk
