8366529 BMW E38 E39 Front Right Door Module PM-BT – OEM Used & Tested

Description

This BMW front right door module is a genuine OEM electronic component for BMW E38 7 Series and E39 5 Series vehicles. Primary OEM number 8366529, with the PM-BT designation shown on the unit. It is designed to manage the electrical functions of the front right door, including the power window motor, mirror adjustment and the central locking actuator, and to exchange switch and status signals with the rest of the vehicle electrical system.

Its job is to receive commands from the window and mirror switches and from the central locking system, and to drive the matching motors and actuators inside the door in a safe, controlled way. A properly working door module supports smooth window travel, accurate mirror positioning and reliable locking and unlocking, which keeps the comfort and convenience system working as the factory intended.

Common signs of a faulty unit include a power window that moves slowly or not at all, a mirror that does not adjust or fold, a door that no longer locks or unlocks with the central locking, intermittent operation after the door is opened and closed, or switch functions that stop responding. When the module fails, the door electronics may behave unpredictably, and related fault codes or warning messages may appear.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 8366529 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 and mirror operation should be performed after fitting where applicable.
