Hmm my temp guage has been deciding to sulk lately :o as in it sometimes just drops to bottom of the scale then reappears a bit further on, then sometimes it decides it doesnet want to get up in the morning and ten mins later is working normally again, so we have an intermittant fault which are always a swine to find, thought i would ask on here see if anyone has come across this before? car is a 95 2.5 TD manual, does anyone know where it gets its feed from???

are you sure its a guage problem, and not, for example, suck open thermostat?

Check the connection to the temp sender on the engine.....

In my experience stuck open thermostat.....leads to temp gauge takes ages from cold to start to move....then never gets to normal operating temp unless stuck in traffic etc....and as soon as go on a run....moves back down to cold area....dodgey connection somewhere i think

sounds more like a poor connection than a stat problem.
Check the electrical connection to the sender and the crimp on the end of the wire at the sender. I have this to be cause sometimes.

On petrol engines, the connector corrodes and doesnt fit tightly onto the sensor so poor contact resulting in no or intermittant temp gauge reading. A new crimp connector fixes it.
I dont know where the sensor is on the diesel (ask Finlay?) but it probably uses the same type of sensor and connector so would have the same problem.
If the connector is OK then move on to the thermostat as suggested

discovered more today!!!! gauge worked fine till i hit a bump then disappeared back down, till i went round a roundabout and while cornering it reappeared!!!
came off r.about and it went again so on a straight road i jerked the steering wheel to the right :o and it came back on!!! so think its a loose connection somewhere had a look for the sender unit but only had tren mins on it and couldnt see it, anyone any idea where it lives on the diesel???
