Descrizione
This BMW door control module is a genuine OEM electronic component for BMW E38 7 Series and E39 5 Series vehicles. Primary OEM number 8378773, marked PMBT Low. It is designed to control the power window, the central locking actuator and the related switch functions of the door, and to report the door status to the vehicle body electronics.
Its job is to read the switch inputs and the central locking commands, to drive the window motor and the lock actuator accordingly and to share the door status, such as open, closed or locked, with the rest of the car. A properly working door control module supports dependable window and lock operation and keeps the door comfort system working as the factory intended.
Common signs of a faulty unit include a window that will not move or only moves in one direction, a door that does not lock or unlock with the central locking, an unresponsive switch pack, a door open warning that stays on, or door functions that work only at random. When the module fails, the door may lose several functions at once, and the body electronics may store related fault codes in memory.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 8378773 before ordering, and check that the connector type, the version marking and the door side match your original unit. Professional installation is recommended, and a diagnostic scan and a check of window and lock operation should be performed after fitting where applicable.
