Comand day/night sensor not working

Ive got a problem today with my comand unit in my 211.

When it is dark outside it does not go inte to the supposed "darkmode".
The climate control display does go into the nightmode and everything else seems to work fine. Only comand is stuck in day mode, and I have to say it is quite annoing driving around with the screen all light up at night.

Has anybody here had this problem and what should I do?
Thanks for your help

have you checked the setting? make sure it it is on auto mode for switching day/night brightness, if everything goes to night mode then that should also unless you disable the screen's auto fucntion.

When this happened to me, I just got the car back from the dealership (Globe Motor Car ) where they were doing some warranty work on the pano roof. Brought it back for them to fix. They said it was a damaged cable from the light sensor to the OCP. You're probably going to need someone with SDS to find the source of the problem.

But I don't think there is one. The day/night info should come via the CAN bus from the light sensor as explained above.

Do we have to ask you too that your COMAND settings are correct (automatic day/night mode)?
