For a while now i've thought our Cayenne's main headlights were too high, and today when I was travelling in a car in front of the Cayenne at night I realised they actually are too high. We have the xenons (litronic?) lights and I think they are meant to be auto levelling. When the car starts the headlights point and down go back up, but they don't change from the up position, and i'm wondering whether the 'levelling sensor' might be at fault? We don't get any warning lights on the dash or anything like that.

Is there anything I can do myself to diagnose what it might be? I've also noticed some covers under the hood which have a picture of lights on them, which i'm assuming might be some sort of adjustment?

Thanks. Does this adjustment also work for the xenon lights? I think I have the auto levelling ones

Upon doing some more research, apparently there is an 'auto levelling sensor' at the rear of the car that could go faulty and not point the headlights correctly. Anyone have any more information on this sensor and how to troubleshoot it? Any schematics or diagrams would be most helpful.
