Hi there ive got an ibiza cupra 2001 and ever since i brought it when it gets up to temp it ocassionally falls back down then shoots up again as if it was a faulty connection. Does anyone know where i should start looking berfore checking behind the dials??????????????

gary, I think the prob here is in the instrument cluster, not the water temp sensor. I know cos my mother's polo does the same and scanning it, it came out it was the temp gauge that had a bad contact, not the temp sensor,,, error was in block 17 [instruments] indeed.
I've seen quite a few cars with this prob now and still I got no solution for it,,, do I have to take down all the instrument cluster???????
