Heated stearing wheel not working

[JensR]

Hi
I just bought a used Z4 2014 model in germany, I live in sweden. I have just seen that the button for the heated steering wheel doest not work. Do anybody have any idea what to do? The LED light does not turn on when pushing it. I was trying to google the fuse map, I seen it but there no heating steering wheel fuse that I can see. Anybody can help?

Fuse 5 is the one.
Could be the fuse, the switch or the control module (under the steering wheel trim).
