MBZ C250 clock problem
We have a 2013 MBZ C250, Starts and runs fine, but the clock display on the instrument cluster display is frozen.
Symptoms: When car is started the clock displays the time it was started last. Then, after a few seconds, time display changes to the current time. This display doesn't change - stays frozen at the time car was started.
When I try to reset the time using the settings options, "set time" is grayed out. All other settings and display options seem to work correctly.
