I have a 03' Cayenne S with Xenons but without air suspension.
Some weeks ago the "Check Headlight" message began to appear, and the right headlight sits noticeable higher than the left.
Both lights move up and down when they are turned on. It's just that the right one ends up higher than it should.

Could be the adjustment mechanism in the headlight or some height sensor somewhere ?
I suppose there must be some sensor somewhere (despite non-air susp) for the lights to know where to sit...

Thanks
