Temp gauge fluctuating

Hi
Recently bought a GTI, and noticed the temperature gauge fluctuates. Warms up fine then will drop down to 70, raises back up to 90 and just goes between them.
Is this normal? Or a sensor having a mare?
Any help appreciated.

My stat was done not so long ago by a Audi master tech, even he said it took a good few hours. The stat is right at the front below the inlet, a pig to get to apparently !

Main Thermostat will sort this.
Don't mess with Coolant sensors ETC.
Bit of an awkward change. Alternator needs to come off from memory.

Yeap.....your main stat needs changing.
It will take some time to fit due to its locations deep in the bowels.
