It has a rotary knob next to the light switch to adjust headlamps to compensate for load variations.

They are supposed to adjust via the dial on the dash next to the light switch.

if you auto adjustment isn't working, worth checking if it a specific lamp of the electrics itself, worth also checking the fuses
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My 2000 C2 does not have automatic headlamp levelling!
It has a rotary knob next to the light switch to adjust headlamps to compensate for load variations.
Unfortunately this knob, when turned is not doing anything. To enable me to investigate, can any of you wise ones tell me how the system is configured - - motors, fuses etc and where in the car they maybe found?
Any help greatly appreciated.
Thanks for that. I’m going to try another switch first as find it hard to believe both headlamp motors have gone especially as still have the original headlamps, I believe!
I have now removed one of my headlamps to investigate why the dash mounted headlamp levelling switch appears to do nothing. Surprise, surprise there is nothing there .
Can anyone enlighten me as to what may have gone on here and/or provide a picture of what things should look like in the headlamp?

They are supposed to adjust via the dial on the dash next to the light switch. The post relates to old fashion manual adjustment at of the headlamp carrier.
By the way, cannot upload photos to show back of my headlamp for example - issue since new format!
Thanks.

Could be but they have 996 part numbers for adjustable lamps! Sadly the forum system doesn’t seem to want to load my pictures for some reason even though I am following the correct procedure!
