Descriere
This xenon headlight leveling module is a genuine Audi control unit for Audi A8 and S8 D3 4E models. The primary OEM number is 4E0907357, with alternate hardware reference 5DF008278-13. It is part of the factory headlight leveling system used with xenon lighting to manage correct beam position during driving.
Its job is to process signals from the vehicle leveling system and adjust the headlamp aim so the light pattern stays properly aligned as load and vehicle attitude change. This helps maintain safe road visibility while reducing glare for oncoming traffic and supporting stable operation of the xenon headlight system.
Common signs of a faulty unit include headlight leveling faults, warning messages, headlights aimed too high or too low, self-leveling not operating at startup, or inconsistent beam adjustment while driving. Lighting system fault codes and irregular xenon range control behavior can also point to a failing module.
This is a used original part, removed from a vehicle and tested. Match 4E0907357 and 5DF008278-13 exactly before ordering. Professional installation is recommended, and coding, programming, calibration, or adaptation may be required depending on vehicle equipment and system configuration.
