Description
OEM number 8378635, Siemens/Hella code 5DK007047-25 — a genuine BMW 5 Series E39 Body Comfort Control Module removed from service, tested, and available as a proven OEM solution at a fraction of the new part price.
Fitted centrally within the E39 body system, this module directs the central locking mechanism for all doors and the boot, enables one-touch window operation and the comfort-close feature activated by holding the remote key, manages the interior and courtesy lighting cycle on door opening and closing, and controls the boot illumination. On equipped versions, it also handles heated seat scheduling and power-folding mirror operation.
If the central locking remote and door button go unacknowledged, if windows stop operating in one-touch mode, if interior lights fail on door opening, if the comfort-close function stops, or if the boot is no longer included in the locking cycle, the body comfort module is the prime suspect.
Match OEM reference 8378635 to your car before ordering. Professional installation and BMW ISTA coding are required post-fit. A 14-day return window applies.
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.
