that is autoleveling, mandatory in Europe on HID headlights, as opposed to manual leveling... in the US we never had manual leveling, it is bad enough people drive with blinkers on for miles, let alone "dial" headlights into oncoming traffic... lol...

i think the autoleveling is mandatory on HIDs in the US too... the adaptive lights were introduced in the facelifted ones, starting some specific production date...

if the rain sensor in yours is acting up, it will affect the lights coming on... how is your fuse 41?
