Adjusting Base level of Bi-Xenons


Recommended Posts

Since I installed by RoW M030, it seems like the headlights are low compared to our other cars. I know these are self-adjusting, but on my Audi I was able to adjust the base level of the Xenons and then the self adjustment goes from there using my adjustment as the baseline.

But on this 996, I took the rubber cover off the "vertical adjustment" and I can't see or feel any kind of knob or screw in there. Am I missing something?

Here's a quick way to adjust the base level of the bi-xenons : avg the front and rear ground to wheel arch height . Mark with tape a line 0.5 " lower on garage door or wall . Back up car 25 ft and adjust horiz cut off there , assuming level surface . It's done !

( The center of the bulb is 1.5 " above the wheel arch . Manual specifies aim line 2 inches below center of bulb .)

You can use 6 " - minimum lenghth screwdriver with a blade minimally 5 mm wide if you don't have that long an allen wrench.

On my 2002 Turbo manual , the directions are printed WRONG . When I rotate the vertical adjuster CLOCKWISE , the lights move UP , not DOWN !
