HID Xenon=Present
I just finieshed installing HID kit for my 2009 E350 4Matic and need help. Both headlights and fog HID's are flickering and i understand that you have to change the Xenon=Present via Star Diag on the ECU. My MB dealer doesn't know where to change this setting. Does anyone know exactly where it needs to be changed? Please help, thank you
