Right side control buttons not working on steering wheel

[Zammy]

Hi All,

I have a 2007 320d E90, the right hand side control buttons (air circ, cd/tuner and scan buttons?) on the steering wheel do not work although the left side volume control button does work, i have no bluetooth so didn't expect the other buttons on the left side to work anyway.

Will this just be a new fuse or am I looking at a bigger job?
