Xenon leveling help

This is my first message, so Hi to All! my english is a bit poor I am spanish.

I was looking for to someone with the same problem and voila! i have found this thread.

I have the same problem, before when I was climbing the pronunced ramp of my garage I saw with a small delay like the xenon were adjusting the level. Now the xenon are always at a fixed level. The xenon does the first check(goes up and down) when starts but after it never moves again.

I have been questioning myself if before the xenon were adaptable, but I am sure it was. Is there any knowed fix for that?

Also, 1 time of each 100, the xenon leves goes crazy and extremely point up(2nd floor of a building!!!) and the only way to fix it is to stop the engine and restart the engine.

I was at the dealer and they didnt found anything wrong, but I really doubt they tested something at all.

Greetings.
