How do I know if my module is faulty....?
Having problems with your central locking not unlocking one or more doors?
This may be a faulty door lock actuator assembly, or else one or more relays in the GM5 module are faulty.
If the fuel filler door also doesn't unlock, and/or the problem is worse in hot or cold weather, then almost certainly your GM5 is at fault. The problem will be intermittent at first, usually with unlocking rather than locking, and getting worse in hot weather, before finally failing completely. you may also have immobiliser and window fualts as the gm5 reylays control most of your BMW once your purchase a repair please send your module with your name address and ebay user to the address which will be provided the purchase is for the repair and return you choose your return deliverer when ordering.
