Ingo had the same problem recently, guage at 100 or more with the key off. I 
believe unplugging the black connector to the IC made it fo off, not sure 
what he actually found to be the problem.

The guage is run off the front sender on the drivers side head. The one on 
the back of the passenger side head is the coolant temp sensor for the ECU 
calculations. The one on the bottom of the radiator is used for the fans, 
along with the one on the drivers side front, IIRC. If you unplug the gauge 
sender, the fan should run, I don't recall what the guage does then.

In the end, this sounds like an instrument cluster problem.

HTH,
