I really need to adjust the xenon headlights of my XE 2.0D. I found out that I can adjust the low and far lights with screw 1 simultaneously (see photo). But what is screw 2 good for? I couldn't find out. I hoped this adjusts the far lights, but I have the impression nothing really happens when I turn these. Can someone please give me an advice?
Thank you very much.
P.S. Sorry, but I don't know the exact terms for what I call "low" and "far" lights. I hope, you understand what I mean.
