Pretty much the easiest thing to do is replace. My guess is the screen is bad. In that case, the unit in the gauge cluster assembly needs to be replaced. Very easy job, pop out the cluster, unplug the cables on the back, and there are 2 screws holding the temp display. I am parting my 300SEL and I have that unit in working condition showing all digits/segments. Its in *F as well. If you need it, PM me.
