NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
High Intensity Discharge (HID) headlights provide bright, uniform lighting to help you see and be seen. The light comes from an electric arc between two electrodes in the gas-filled bulb. Over time, the electrodes can wear down and the gap between them will get wider. The HID lamp’s control unit then increases the voltage to keep the arc’s brightness constant. However, the commonly called “Xenon” bulbs will also ultimately burn out. Before they burn out, HID lamps can flicker. A message will then appear in the MFI. This is your reminder to see an authorized Volkswagen dealer or an authorized Volkswagen Service facility to check the headlights.
