Temperature gauge

[matthg40]

My temperature gauge has suddenly stopped working.ive not touched anything my g has just come back from it's mot and suddenly my temp gauge has decided to stop working.does anybody know where the sensor is so I can see if anything has broken down or if there is any issues.many thanks as always Matt

The temp gauge gets its signal from the black temp sender on the thermostat housing. Is your fuel gauge working too? My GT has a strange issue where the temp and fuel gauge will both stop working for a while then suddenly without even touching anything they will come back. This has lead me to believe the temp and fuel gauge share a circuit, but I have no idea as to why they stop working so randomly.

Does anybody have a spare temperature switch or know where I can buy one from as Vw say they are no longer available to buy.so I no longer have a temperate gauge and I hate not knowing how hot or cold my g is.if anybody has any advice please let me know thanks in advance.oh and I really don't want to fit an aftermarket temp gauge I'd rather get the original going from possible.

Gsf sell them for about £8 each. Replace the blue one while you're there.

If it turns out that the gauge itself is broken, the temperature and fuel gauges are a plug in module in the clocks that can easily be changed.

Where can I get a module from mate? My temperature needle hardly rises!

You will need to get a spare set of clocks and dismantle them to get the combined temperature/fuel module. I think that bit will be the same across all Mk3 Polo models.
