Temperature gauge

As above,not working anymore.

Anyone any ideas as to why or what to check?

Cheers fellas

check the brown temp sensor.
I think you can also check the guage by earthing the brown/purple wire from pin26 of the blue connector.

Cheers Dave,another couple of things to check,incidently,reading that thread mentions the fuel gauge,mine works,but the light has stopped coming on,could be those loose bolts mentioned.

Best get on and investigate

First thing to do is earth the temp gauge wire at the sensor end. Gauge goes to full hot, then change brown sensor. Doesn't move: look elsewhere.
Disconnect the C101 engine loom plug on the bulkhead by the fusebox. Earth pin 4 of the body socket with a short piece of wire. If gauge goes to full hot, then check out a round plug and socket fitted to the metalwork under the middle of the inlet manifold. Doesn't move: start pulling out the instrument cluster.

Important point of fault finding is not to dive in changing, checking and dismantling things at random. You'll end up possibly curing the fault temporarily, but not knowing what it was, and introducing a few faults you didn't have before!
