Description
This is a genuine BMW front door module for BMW E65 and E66 models, supplied under OEM number 61356921979 with hardware reference 5WK48002. It is an original electronic control unit used in the front door system, designed to manage key door functions and support proper communication between door components and the vehicle’s electrical network.
Its job is to control and coordinate electrical features within the front door assembly, such as window, mirror and locking-related commands, while ensuring smooth signal exchange with other onboard systems. A properly working door module helps the door electronics respond accurately and keeps everyday convenience functions operating as intended.
Common signs of a faulty unit include intermittent window operation, inoperative central locking on one front door, mirror adjustment faults, loss of door-related electrical functions, or communication errors stored in the vehicle. Electrical glitches that affect one front door only can often point to a failing module of this type.
This is a used original part removed from a vehicle and tested before sale. Match 61356921979 and 5WK48002 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle configuration.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
