Right Scroll Button Not Responding

    Today I took my car in for inspection, and when it came time to check the odometer… we were unable. The dash display was set for energy, and attempts to change it using the right scroll button were futile. In fact, the car is no longer responding to the right scroll button at all. Pressing it doesn't toggle the climate control, turning it doesn't change the temperature, holding it down doesn't bring up the choice of displays. It seems totally dead.

    So, I tried restarting the MCU by holding down both scroll buttons. This worked, in the sense that the MCU did in fact restart. (Meaning, I guess, that the scroll button hardware must be intact?) Afterwards, though, no improvement. Right scroll button still not working.

    Last night I ran the software update to v10.2 (2021.4.11). Is this a firmware problem?

    Most likely the scroll wheel itself or the harness. Either way, needs replacing unfortunately. Easy to do yourself or not terribly expensive overall to have them do it.

    I just had the same problem - except that both right buttons were also non-responsive. A Ranger came to my place and replaced a wiring harness and switch assembly inside the steering wheel.
