How to we MANUALLY adjust xenon headlights?

My xenon headlights are too low despite being adaptive and the lights cross eachother and I'd like to adjust them WITHOUT going to the dealer.
Surely we have adjustment knobs some where on the lights don't you think?
My BMW had them.
Thanks gents.

have a long 6mm hex key ready, and try to locate the headlight unit in your engine bay area, you will see a dark green hex key slot which will allow you to adjust it either up or down and there is another dark green slot where you need to insert thru the metal chassis support are to reach the ones that can adjust it left or right, not sure if you understand what I am implying here, but with a torch light to locate the green slots is a lot easier, once you found it, you should be able to know what to do next.

Smashing, will try it tonight. Thank u jelly
