At first I tried to remove the f***ing steering wheel from the column I tried everything the special tool as shown in the manual and a big hammer to bring the column out of the wheel at last I even tried to drill a big hole in the column. After a good hour and a sticking broken screw in the steering wheel I was at my wit's end.
Now the column had to go I just cut it with the angle grinder next to the end of the steering wheel.
A bit WD40 and two hits with a hammer and it was gone.
Okay now I have a new column and a working horn button
here some pictures:
