Faulty TEMP gauge

[Phantom]

I have just purchased a 2002 1.6 FSi Sport. Unfortunately, the temperature gauge works 1% of the time. By that I mean it just doesnt work but on the odd occasion it springs to life and registers at 12 o'clock.

Question I have is what could be causing this?
Is a sensor somewhere in the engine bay and if so whereabouts?
Is this 'AUDI only' or can I sort it with the right tools and parts?

If anyone can help it would be much appreciated.

Not had this on my A2, but exactly the same on my Passat - it was the temperature sender that was the problem (it may even be the same part). The needle mostly sit on zero, and occasionally move up to mid position.

I had the same problem on my 1.4 petrol recently,it appears to have been caused by damp getting in when I hosed the engine bay down.

A good run down the motorway(160miles)in one hit appears to have generated enough heat to dry all the moisture up and sorted it.

However yours could be a completely different fault/problem.

90% likely the Temperature Sender Unit , mines a 2002 1.4 petrol, was told its common amongst the VAG range as they all share similar parts.Checked with a better Audi delaer & the oart costs £27 ish .They charge £150 to replace it though so i got a local VW garage to do it .Works fine now .If replacement doesnt work then it could be the Thermostat..Good luck

had the same problem with my 1.6 sport and it was the temp sender but i was lucky and had the audi year warranty.
