1) Low beam burned out, hi beam ok 2) LAMP error in the display all the time 3) Inspected old low beam, filament was melted. High beam bulb looks fine 4) Got replacement bulb, installed good high and low beam 5) Lamp error is gone, but still no low beam 6) New bulbs works as high beam 7) If I put a bad bulb in the high beam, I only get a LAMP error when I turn on the high beam Normally I would say blown fuse, but not on a Canbus system. If this was a bad wiring connection it would still show a LAMP error even with a good bulb, right? And the original bulb did fail. Do I have do maybe do some kind of Canbus reset, and how? What else could be wrong?
