Description
This BMW battery power distribution module fits BMW 1 Series E87 and 3 Series E90 models. Primary OEM number 6936649 identifies the unit used to manage and distribute main battery power within the vehicle’s electrical system.
Mounted in the battery power circuit, this module channels power from the battery to key vehicle systems and provides protected distribution through integrated high-current connections. It plays an important role in stable power supply, helping maintain reliable starting, charging and electrical operation across multiple circuits.
Common signs of a faulty unit include intermittent loss of electrical power, no-start conditions, battery supply faults, warning messages, blown main fuses, or sudden shutdown of one or more vehicle systems. Heat damage, corrosion at the terminals or internal fuse failure can also lead to poor continuity and unstable voltage delivery.
This is a used original part removed from a vehicle and tested before sale. Match the exact OEM number 6936649 before ordering. Professional installation is recommended, and wiring, battery terminal connections or related system checks may be required during fitting.
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.
