common problem with clock/temp display in E30s

try removing the unit (pop off plastic 'rim' around it with
 a knife.. then squeeze the plastic snaps and pull unit out)

unplug it and clean up the contacts with contact cleaner
(from an electronics store like radio shack)

this often cures the problem

sometimes there are problems with solder joints inside the
unit but the above solves the problem most of the time
