E39 (1997 - 2003)
I replace my module with this
(L04257 1997-2003 BMW 5 7 Series Low General Body Control Relay BCM GMIII OEM) and it seams all my windows and doorlocks work now but the back hatch will not work.
Deos the car need reprogrammed or do you think the module is out of a 528 sedan and not a wagon...
