Check coolant level and under the oil cap. If it's like a jar of helmans under there could be headgasket

If the needle shoots to high as soon as you turn on the ign then its probably a short in the wire going to the temp sender unit, a faulty sender unit or a faulty guage, in that order I'd say.

The temperature sender failed on mine (gauge was stuck on cold), was about €20 for a new one but was a bollocks to fit (it's behind the engine in the 1.3).

normally i would suspect the sensor, but since it stays high with the engine & I presume ignition switch off could be the gauge or a short,

disconnect the wire from the sensor and see if it falls back, if so it's most likely the sensor itself if still staying high you will have to search further
