2. Loss of Control Functions: Buttons for volume adjustment, track/radio tuning, hands-free calling, or navigation through the digital instrument cluster menus will stop responding entirely or work only intermittently.

Smart Buying Tip: Do You Need the Full Set?

Steering wheel controls in luxury vehicles tend to wear out at a very similar rate on both sides due to daily use.

Buying the Right Side? To maintain a symmetrical aesthetic and avoid noticeable differences in texture, color, or wear between old and new buttons, we highly recommend purchasing the corresponding left side at the same time. Refresh your entire steering wheel layout at once and save on installation costs!

Because Mercedes-Benz offers a wide array of steering wheel configurations depending on the production year, trim packages, and specific driving aids, it is absolutely essential to verify compatibility before ordering.
