How do you replace the HID Xenon Headlights on Passat W8?

You have to remove the headlamp from the car. To do this remove the grill, undo all bumper fastners and outer wheel arch liner fastners x 3 and screw that holds bumper to the wing x 1 (on both sides of car). Remove bumper retainer screws x 5 behind grill, pull bumper forwards to unlatch from wing, undo headlamp screws x 4, 2 top and 2 bottom, disconnect wiring loom from headlamp and using a bit persuasion (or have someone pull the bumper forward) remove the headlamp from the front of the car. Remove cover covering the lamp, 3 screws and 1 catch, replace bulb and reverse procedure for re-install. Dirvers side you have to remove the air intake duct (just pull off) and passenger side you have to remove cover covering Power Steering fluid and abs system before undertaking the above.
