8377601 BMW E38 E39 Door Control Module PMBT Low – OEM Used & Tested

Descriere

This BMW door control module is a genuine OEM electronic component for BMW E38 7 Series and E39 5 Series vehicles. Primary OEM number 8377601, marked PMBT Low. It is designed to operate the power window motor and the lock actuator of the door from the switch and central locking commands, and to send the door status to the vehicle body electronics.

Its job is to evaluate every command coming from the door switches and the central locking, to power the window motor and the lock actuator in a controlled way and to keep the rest of the car informed about the state of the door. A properly working door control module supports smooth glass travel, secure locking and unlocking and correct operation of the door comfort functions every day.

Common signs of a faulty unit include a window that is stuck, slow or dead, a lock that fails to respond to the key, the remote or the central locking, switches that stop working, intermittent door faults after the door is slammed or washed, or a door warning that never goes out. When the module fails, several door functions may disappear 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 8377601 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.
