This has been an issue for a while and I went through all of the maintenance items in the Nav screen but could never get the gauge cluster message to go away. I have now installed a Tesla style HU which doesn't have the maintenance log (a good thing in IMO). I thought it would take care of the gauge cluster message, but no, still there. Now I really don't know how to make it go away. I did check for OBDII codes thinking if there was one I could clear it but there aren't any. Any thoughts anyone?
