6904248 BMW E38 E39 Door Control Module PM-BT – OEM Used & Tested

Description

This BMW door control module is a genuine OEM electronic component for BMW E38 7 Series and E39 5 Series vehicles. Primary OEM number 6904248, marked PM-BT. It is designed to coordinate the power window, the mirror motors and the central locking actuator of the door, and to pass the switch and status signals to the vehicle body electronics.

Its job is to collect the commands from the door switches and the central locking, to drive each motor and actuator in the door at the right moment and to report the door status to the rest of the car. A properly working door control module supports dependable window, mirror and lock operation, so that the everyday comfort functions of the door work as the factory intended.

Common signs of a faulty unit include a window that is dead or slow, a mirror that will not move, a lock that does not respond to the key, the remote or the central locking, a switch pack that no longer reacts, or door functions that fail only in certain weather or driving conditions. When the module fails, the door may lose several comfort functions together, and fault codes may be stored in the body control memory.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 6904248 before ordering, and check that the connector type and the door side match your original unit. Professional installation is recommended, and a diagnostic scan and a check of window, mirror and lock operation should be performed after fitting where applicable.
