Function and location
The potentiometer is the brightness control (dimmer) for the instrument lighting of the 190 – the entire instrument lighting runs through this single control.
It sits on the instrument cluster and is plugged in, nothing needs to be soldered on the vehicle. To replace it, the instrument cluster is removed and the potentiometer is swapped – usually a matter of 20 minutes.

How can you tell a potentiometer (dimmer) is faulty?
- The instrument lighting flickers
- The lighting suddenly goes dark when turning the control
- The lighting fails completely
- The brightness can no longer be adjusted continuously
In the vast majority of cases, it is not the instrument cluster that is faulty, but precisely this potentiometer.
