Defect on headlamp adjustment Xenon

Hello municipality, on my Sweden the following problem has occurred for the second time. The right headlight (Xenon) no longer adjusts, lights estimated 10 meters in front of the car (in the dark really corrosive). The height adjustment on the left works quite normal. The whole thing was already present, then after 2 weeks “repaired” itself, funzte arber just only 2 weeks normal. Do you know advice or have similar experiences?
