Hi hope someone can help. I have a 2006 307cc can anyone tell me what the ecu in the boot controls. For sometime now the roof had not worked. Now the rear windows have stopped operating and also now getting a message on my dash saying there is a airbag or seatbelt pretensioner fault. The reason i ask about the ecu is that i stripped out the rear trim in the boot to have a mess around with the roof and found that when i pressed the button to operate the rear windows i hear a click coming from the ecu. Wondering if there could be a connection. Any advice would be great thanks.
