2012 E350 Cabrio
The car has factory HID headlights. 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. Thanks much.
