I wondered if anyone could help. Last September we replaced the Body Control Module as Vauxhall said it was faulty and this was the reason the immobiliser light kept flashing and it would not start. They said the heater control module had also gone even though it was fine before we took it to them. It has been working fine for 5 months then the same thing, wouldn’t start. I disconnected the battery and reconnected which then got the car starting again and replaced the battery now as I’m was told it could be the reason. However it has just happened again. I don’t trust the Vauxhall main dealer, they had my car for weeks and it still isn’t right and ended up with me spending a lot if money on it without curing the problem. Can anyone help with what to do? Does it needs some form of reset. Any help appreciated. Thanks
