I drive a 2008 FH and just recently the display for the gearbox on the dash goes blank, where has three segments, one with E, E+ or P, then a box with A or M, and the 3rd segment displaying what gear your in.
Now when it goes blank the auto gears continue to work but you do lose the operation of the Power mode button on the top of the shifter…
Tbf shes an old gal and it doesnt cause any real dramas but wondered if any other volvo drivers have come accross this.
