Is the car kept in a warm dry garage, or in a cold damp box?
Dampness on the circuits behind the dash is always a potential money pit as MMC, in their infinite wisdom, didn't see fit to pot the electronics.
I'm still waiting for a component, less than £100 but without it the buttons on the dash don't illuminate.
Since 2014 I have had more "dash module" issues than any other,
