Just installed aftermarket Xenon lights on a 99 E320 (W210). Lights are fine but am getting the 'Bulb Inoperative' warning message in the instrument cluster. Looked through thread and found the dealer can make adjustment in computer for xenon bulbs. 3 different dealers and no go because that functionality was not put in until 2000 and mine is a 99. Installed a 12volt 1 watt bulb on either side of the original headlight connectors hoping to trick the computer and that did not work either. Anyone have other ideas on how to resolve this issue?
Thanks
