Help, center control switch s550
Good evening,
I have been stumped with a problem that maybe someone can help.. my center control and my touchpad both stopped working…I am almost sure nothing leaked on them but I find it strange that both stopped working.. on the center control switch only the hazard lights button works. I can’t access any other buttons.. pls help
Nothing works accept the hazard lights button

Check f331 (5A) @ interior fuse panel if fine, pull for several minutes in an attempt to reset. If this fails have someone pull codes using Xentry (MB diagnostics).

If I had to guess your problem is on CAN A conection as the hazards work through the front SAM IIRC.

With xentry can you communicate with the control unit?
Any CAN errors?

Yes that's not good
Have you had anything coded recently?
It should not have changed to not installed on its own
