Steering wheel buttons, horn, and shifter paddles not working
I have a 2007 s550, I just got the car back from having the airmatic pump replaced. A couple days later all the buttons, horn, and shifter paddles are not working. Anyone have an idea of what could be the issue?

My guess is that they accidentally disconnected some wires when working on your car. Take it back and have them rectify it.

I agree, request they perform a quick test using MB diagnostics to pull fault codes. There was a bulletin released but doubt this pertains to your situation nevertheless, it documents steering wheel electronics can be replaced separately if need be.

Steering wheel buttons not working
I had a similar problem Steering wheel buttons and horn would not work. The weird thing was that starting the car the next morning everything worked. It was diagnosed as steering column control panel
