Description
OEM reference 6948577 fits the BMW E60 5 Series and E65 7 Series as an LM LWR Light Module with headlight range control. LWR (Leuchtweitenregelung) denotes the integrated automatic headlight levelling function. This is a genuine used component, fully inspected and tested prior to dispatch.
The LM LWR drives automatic headlight range adjustment, controlling levelling stepper motors in the headlight units in response to signals from ride height and load sensors. The module ensures consistent and compliant beam angles regardless of vehicle load. General lighting switching functions are also handled by this unit.
A defective LM LWR typically causes headlights to remain fixed at a single beam angle, failure of the automatic levelling function, headlight range warning messages in the instrument cluster, and stored fault codes in BMW diagnostic systems.
Always verify the OEM part number against your vehicle’s data before ordering. Professional installation is strongly recommended. BMW ISTA coding is required after fitment, and headlight levelling sensor calibration may also be needed. 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.
