Hi
I have the same problem, did you find a solution?
The drivers door works and sends a signal to the pump in the boot which just buzzes for about a minute (it stops buzzing if I open the boot), the petrol cap, passenger door and boot do not lock.
Also I cannot lock the boot using the key so maybe this is stuck/jammed and causing the rest to fail?
Does the boot pump send the signal to the passenger door and petrol cap? Or do I have another problem?
Thanks
Rich
