Odd symbol

[zym]

Recently I've occasionally seen a small "X" appear next to the right hand temperature numbers on the climate control display, and it disappears after a couple if minutes. I assume it's indicating something's not quite right, but no idea what as I can't find it mentioned in the manual etc.

Anyone here know what it means?
