There's a bit of info here which'll tell you if it's possibly the module marked 43 - it explains how to check the electrics are ok - then you can go on to test the stuff in the engine bay....

What engine is it?

Mine (1.9DG) failed and changing the sensor didn't work, it turned out there was corrosion on the sensor plug and I had to cut the old one off and connect a new one on.

thanks for that chaps, i will have a go this weekend and let you know how i get on.

iirc you are on late water set up, so joining the two connections of the plug together will move the gauge if its not the sender or the wiring.
AIdan knows the value for testing the sender, i cant remember....too much stuff to remember , an that aint one of them!!! lol!!!

its normally the plug or wiring corroded......
