I have stock xenons on my audi and i kept getting the dipped headlight warning because my passenger side light kept going out so i bought aftermarket d1s bulbs to replace it and i did and now it hasn't gone out....yet and i think its fixed but now i have a new warning light displayed related to the headlight but i don't know what it means and i couldn't find it in the manual either

here is the warning it looks like the headlight symbol with an arrow pointing upwards

 

That's the adaptive lighting fault indicator. Need to use VCDS to determine fault code in module 55 Xenon Range ; could just be a case of checking all your connections to the adjustment motors that swivel the headlights.
