Description
This Mercedes-Benz AFS xenon headlight control module is a genuine OEM electronic component for the Mercedes W211 E-Class. Primary OEM number 2118703126. It is designed to control the Adaptive Front lighting System of the xenon headlights, managing the swivel motors and the leveling function so the light beam follows the road ahead instead of pointing straight forward.
Its job is to read the steering angle, vehicle speed, and load information from the vehicle network, then turn the headlight units into curves and keep the beam height correct under all conditions. This improves visibility in corners and prevents glare for oncoming drivers. A properly working AFS control module supports safe night driving, correct beam alignment, and reliable operation of the entire headlight system.
Common signs of a faulty unit include a headlight or AFS fault warning in the instrument cluster, headlights that do not swivel in curves, lamps stuck in an off-center position, incorrect beam height, flickering or failing xenon lamps, and fault codes stored in the lighting system memory. When the module stops working correctly, the headlights may lose the cornering function or stay fixed in a wrong position.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 2118703126 before ordering. Professional installation is recommended, and headlight calibration or coding with a diagnostic tool may be required where applicable, so confirm the fitment details for your vehicle before you buy.
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.
