SYMPTOMS OF FAULT

Knob rotating but no response on the monitor. Knob works up-down-left-right but no rotation. When the wheel is turned, no reaction on the screen will be shown. All other functions such as confirming and tilting the controller are given.

THE FAULT

Snapped shaft mercedes comand center control knob dial button unit

A plastic shaft within the scroller knob unit snaps causing the scroll function to no longer work on the screen.

It is a common fault on these vehicles for the comand controller knob to stop functioning correctly. A poor-quality plastic shaft within the controller knob unit snaps. This causes the common symptom of the scroller rotating as normal but for there to be no reaction on the screen. If all other functions are working except the scroll this indicates this shaft has deteriorated and snapped, this is an extremely common fault. Mercedes Benz fix is to replace the complete knob and button unit, this is extremely expensive and would only fail again.
