Can someone point me the right direction as to where to find it. This is the issue I am having, when fog lights are on, and I hit high beams, most cars I have driven turn the fogs off as to not totally blind other drivers. In my E, the high beam lamp comes on, sticks, and the left rear brake light burns a fuse. I checked the socket to the the rear lamp, and the wiring harness, all come back ok. Bulb is fine, even switched it with RH lamp just for fun. The 10 fuse blows with this issue. So, my conclusion, please correct me if I am off, is the HCM is defective. If anyone has pictures or a diagram that would be most helpful too. Thanks Dave.

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?

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. Nothing happened, so I repeated that on the front sensor, again seeing no movement.
