Well do you have any more information than that? My auto-leveling headlights do not work because my rear sensor (G76) is not working properly. I have to reset the level on the headlights via VAG-COM so that one of them isn't pointing on the ground 6 feet in front of the vehicle.

If you have VAG-COM (and please just do a search if you don't know what it is) then you can read the voltages coming from the various level sensors and obviously if it's not sending anything (0.Xv compared to ~3.0v) you can assume that the sensor is not working. I would check the wiring between the sensor and module (don't know where that is though), but I would think that replacing the sensor would be your best bet.
