Mercedes C Klasse Hybrid Damping Adjustment Fault
Summary of the thread
A 2022 Mercedes C Klasse hybrid with 173,997 km is experiencing a 'damping adjustment fault' error, resulting in a warning light and a bumpy ride. The suspected cause is a cable or plug connection issue within the suspension system. The problem was confirmed to be a corroded connector, which was resolved by cleaning it at a workshop, eliminating the error and restoring ride quality.

Intermittent? Not really. The light came on, and the bumpy ride started immediately. It never went away. Were you able to diagnose it yourself, or did you take it straight to a workshop?

I went straight to the workshop. It ended up being a corroded connector in the suspension system, just like you suspect. Do you have the equipment and know-how to check the wiring yourself? If not, I'd recommend taking it in. It's better to be safe when it comes to suspension.

Thanks for the advice. I took it to a workshop, and you were right, it was a corroded connector. They cleaned it, and the error's gone. The suspension issue is resolved.

Damping adjustment fault, bumpy ride and a warning light... sounds familiar. I had something similar happen with my old Volvo, different car, but the symptoms were strikingly alike. Did your suspension issue start intermittently, then become permanent?
