Description
OEM part number 1379741 fits the BMW E32 7 Series (1986–1994) and E34 5 Series (1988–1995) as a Body Comfort RM (Relay Module) control unit. This relay-based body control module is a genuine used part, fully inspected and tested before dispatch.
The RM Relay Module manages key comfort and convenience functions on these classic BMW models, including central locking for all doors, electric window operation, interior lighting control, and remote central locking where fitted. This relay-based architecture controls these body functions without the bus-based complexity of later platforms.
A defective RM typically causes complete or partial central locking failure, electric windows becoming unresponsive, interior lights ceasing to function, and remote central locking failing to operate on equipped vehicles.
Confirm the OEM part number matches your vehicle before ordering. Professional fitting is recommended. Some variants may require basic adaptation using older BMW diagnostic tools such as GT1 or ISTA; others are plug-and-play. Returns accepted within 14 days.
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.
