I'm not sure, but I can give you the run-down:
1) Unplug the wire harness from the top/rear of the headlight housing.
2) Remove headlight assembly from car. Follow the instructions included in this headlight modification thread:
http://www.audizine.com/forum/showth...ont-reflectors
NOTE: If you have a B8.5, there is a condensate drain/vent tube connected to the headlight housing. When you have the headlight assembly pulled "half way" out form the car, you need to disconnect the black rubber drain tube from the fitting on the bottom of the headlight housing. This does not exist on the B8 headlights.
3) With the headlight housing removed from the car and looking at the back of the housing, remove the round rubber cover closest to the outside (reflector side) of the housing. When you remove the cover you will see the base of the xenon HID bulb which looks like this (although your bulb brand/type might be different):
4) Pull the silver connector straight down to disconnect it from the base of the bulb.
5) Grab the base of the bulb and twist to release it from its sealed seated position. I cannot remember whether you need to rotate it clockwise or counter clockwise, but give it a little twist and you'll feel which direction it wants to go.
6) Put on a pair of rubber gloves to avoid your skin oil coming into contact with the xenon bulb surface, then CAREFULLY remove the bulb from its socket. There is an external filament/wire (I'm not sure exactly what it is) on the bulb that is protected by a small plastic tube, but if you put too much pressure on the tube it can break. There is a notch in the bulb seat of the headlight housing that this external element can pass through during bulb installation and removal. When extracting the bulb from the housing, use a steady hand and pull the bulb straight out to avoid contact between this part of the bulb assembly and the housing.
6) Insert the new bulb all the way in against the seating surface, then twist in the opposite direction of removal to seat and seal the bulb into place.
7) Plug in the silver power connector to the base of the bulb and reinstall the round rubber dust cover onto the back of the housing.
8) Put the headlight assembly back into the car in the reverse of the instructions included in step 2.
