Hello everyone,

I'm new here

Have a problem with my 2015 v class

The instrument panel is and remains completely black, no light no km position no tachometer nothing.

The engine starts the radio and the gearbox does work. electric windows and seat heating also work

Buttons on the steering wheel don't do it

Also my electric sliding doors and the electric tailgate don't do it, very sometimes when I disconnect the battery the door works 1x

The problem suddenly came but I saw that every time I turned off my car the km position after rest and trip was reset to 0 km and that the hands with contact fagged a bit.

I measured this afternoon and measure on the plug that is on the back of the km counter only 7V and with reading out Obd on circuit 30 4V

Who has an idea ? I don't remember.

The cluster has been sent and will be checked this week but I'm not sure if it is broken.

Thank you very much in advance

Is there anyone who can look for me in a scheme where the 12v wire that is on the instrument panel comes from, do you think it comes from the Sam or from the fuse box?

Thank you in advance
