Dear forum members, I am new to here and I have a W204 C280 which I very love. A few day ago, the intelligent light system startup is different from before, the light (set at auto mode) would not "move up and down" when starting my car. So, is it must moving up and down when startup or sense automatically when it is needed? Please reference the following 0:05-0:09 for exactly what my meaning.

Does anyone know what is the problem and how to solve this issue? The lights will not auto leveling when startup the car.

Do they appear to be out of alignment when you're driving -- either too high or too low?

Albert_Einstein

Hi ChuckinTucson, they are well aligned when driving but just no auto leveling when startup my car, so, not sure what is the problem besides.

Do the headlights move left and right before up and down? If it is just the up and down alignment, I would bring the car to a workshop. The ILS may need to be initialized again on the computer

Albert_Einstein

No left, right, up and down movement anymore. Not sure if this is caused by not enough battery voltage or any other issues else?

Moreover, the headlights can be initalized again? That means reset the headlights to the very beginning?

It may also be a bad ILS control unit, which is located under the right front floorboard

Would you please show me a photo about the ILS control unit and the exact location on the floorboard?

Thanks for your advice, capt_paul.
