Can't figure out where the headlight control module and ballast voltage converter are. Thread Tools. Rate Thread. Received 13 Likes on 12 Posts. I can't figure out where the headlight control module and ballast voltage converter are located. Any help locating would be great. I believe the ballast voltage converter is under the headlight?

My driver's side headlight fails after a few minutes and I get the "adaptive headlight inoperative" message. I swapped the bulb with the passenger side and the problem stayed with the driver's side. I ordered a new Hella control module and the unit came with a document that says that before putting it into service "it is necessary to install software and afterwards carry out coding by an appropriate diagnostic tester". Since the car is already set up for HID, is programming the ballast necessary? If so, if I install it then go to the dealer for the programming, do I risk damaging the module or will it just not work correctly? I am hoping this is a plug and play situation.

My auto leveling headlights no longer rise to the occasion when switched on, aimed downward all the time. Looking at the 2 threads below, I figured out the problem could be either or both of the height sensors connected to the suspension at the front and rear of the car, the control module itself, or the headlights themselves. Didn't make sense the 2 light "motors" would go at the same time, so I did some rudimentary troubleshooting. Put the car up on the Quick Jack, disconnected the rear sensor, turned on the headlights, and moved it full travel slowly watching for headlight movement.
