both auto and ON

ok, let me check a diagram, i think the issue will be the cluster,

these were prone to failing, there is even an online service that repairs these.

yeah there is only 7 wires to the cluster, 4 can wires and 1 ground and 2 power supply, so as long as you have power on the red wire with white strip and black wire with blue stripe the cluster is the issue.

hope this helps.

there is power to cluster at these wires, are there any bulbs in the cluster that can be check or replaced ?

it will not be bulbs, they are leds, and no it will be a solder for the circuit board for these bulbs.

I am pretty certain. the older mercedes models we were able to replace bulbs but in this one im pretty sure its leds or you would see the bulbs on the back sticking out

even so all the bulbs would not fail at the same time
