W205 Center Stack Buttons not working

Hello everyone! My girlfriend and I were rudely surprised by the buttons around the clock/COMAND control wheel not lighting up and not working (she hates the auto stop/start feature and can’t turn it off!!)

Has anyone found a solution to this problem? I’ve read around a little bit and have not found any conclusive answer on how to solve this matter…

Is there signs of liquid damage? You might need to replace the whole assembly.

If auto start/stop is the only thing you are concerned about, you could probably code it out with a scanner.

Before that though, I would recommend checking fuses. I am not sure which fuses control that assembly though.

No, no liquid damage. It was working just fine earlier then randomly conked out tonight.

might had been a fuse issue then check those threads for the right fuse to pull and analyze.
