I have a Fiat Barchetta on which my temperature gauge consistently over-reads. The car uses no water and is running at a normal temperature (by all other signs) but the gauge reads very high. Is there any way one can calibrate it? The agents confirm it is operating at a normal temperature.

Hello Dave,

Reckon you should speak to DTR (http://www.dtrsports.com/). They should be able to help you.

Rather than worry about the guage it might be better to first check the sender unit.  Make sure it has the right one for the car, and the connections are good, or if not too expensive, just replace it.

Just a guess.

I have no experience with this in a Fiat, or other metal bodied car, but it is quite common in TVRs. The usual cause is the voltage stabiliser which is screwed to the back of the dashboard. Sometimes it needs replacing, but often just cleaning the connections does the trick. So as Chris suggests, I would have thought that the problem is probably electrical and minor, if you can't find which connection is at fault maybe try an auto electrician.
