2014 ML350 Distronic Plus LED Odometer Display Malfunction

This is now the third time the Distronic Plus LED indicators on the odometer have stopped working. This is a circle of red LED indicator lights around the circumference of the odometer that light up to indicate the current speed set point of the Distronic Plus system. Currently, they do not light up at all. This has happened twice before, and each incidence has been about a year apart. At each occurrence, the dealer didn't seem to have any idea that the LED display existed or what could be wrong, but they installed a software update and resolved the problem. Unfortunately, the LED indicators have stopped functioning once again.

I wonder if there is some combination of button activations that toggles the display on and off. There’s nothing in the manual and I get no useful advice from Mercedes other than, “bring it in and we’ll update the software again.”

Mine were also not working and after a software update they are working again. I don’t think it’s something that can be turned on or off
