There's five screws total...three underneath and two more in the fender well. Remove these five screws and then the molding. This will give you full access to change your fogs as well as side markers. Turn the fog light counter clock wise (looking from the back of the lights) to loosen.

Makes sense they designed it like this to make quick change of bulbs easily accessible. It takes only minutes to remove these screws. I did it with my steering wheel straight. There's room in the fender well for a short phillip. You can always turn the wheels for better access.

Since I have the Xenon, my fog lights looked 'yellow'. I replaced it with those hi-quality white tints using AdvancedOptik HID Match Fog Light Bulbs. http://www.europeanautosport.com/optik.htm. A lot of Audi guys are using these bulbs. It's been almost a year and I always drive with these lights on. No burn outs yet.

I think I've turned my fogs on twice in the 2 yrs I've owned it.

it is my understanding my MY06 Cayenne S Titanium Ed xenon is 4,100K , therefore I should try to match such light intensity and not going over this rating if I would like to get the closest "xenonmatcn". Am I right?

How can it be everybody are just replacing bulbs getting the xenon match they want and I've been going thru different brands without getting closer to match my xenon headlights ?

Am I supposed to tint the transparent fog light glass to bluish color to make that yellow color disappear?

Thanks
