When I turn on the main beam, the passing beam goes off

Servus, someone can help me. I have the following problem with my Audi 80 1.8S: If I have normal light on there and turn on the main light levers off) only the stand light lights up. I know that apparently the end light goes off when the remote lotion light up but also when I do light hooves. So it can’t be the H4 bulbs. The lever on the steering stick is in function as always.
