the radio control buttons located in the steering wheel start not working correctly. when I press the + sound the radio volume goes down and when I press - sound the sound goes up. Also, the cruise control buttons need double-click on it to activate. then after a few months, the Airbag light got On and the radio buttons become completely not working and cruise-control not working as well. but the horn still works well in all positions.


What you describe is caused by a bad clock spring. In most cases at least. I would have the dealer diagnose the problem and then you can decide if you want to take the repair on yourself.

Replacing the clock spring is not that hard. Btw, it will be expensive at the dealer. You can do it yourself and the part is cheap.

Thanks, MercedesMedic,

I'll take the car to the dealer to diagnose it, then I can decide if I repair it by my self or not. 

I would second what MercedesMedic said...


This is not a  big issue, a simple problem, yet frustrating, Do update us on what happened and if it got fixed
