Vauxhall Astra external temperature

During a cold spell over the winter the external temperature readings on my

2001 Vauxhall Astra 1.6 CD went a bit haywire and haven't been right since. The temperature still fluctuates but not consistently, and it overreads by around 10-15°C.

The Haynes manual for my model has yet to be released, and I know it's not a major issue but it's annoying all the same. :-) I'd welcome any suggestions about which part of the system isn't working properly and how to fix it.

With Vauxhalls, the temperature sender unit is inside the NS front wheelarch just behind the bumper. You'll need to replace it. Costs around £30?

Crikey! Was that a fitted price? Last time I had to fit one, the sensor cost about £14 inc VAT!!

Well, that's inflation for you.....

Could the sensor just have got a big lump of mud or something from the road on it, creating a thermal effect? Might be worth finding and cleaning it up first before buying a new one.

If its the mk4 astra it's behind the middle of the radiator opening in the "V" shape just under the badge.

I replaced one on my Cavalier a few years ago - took 10 seconds, part was about 8 quid. Similar problems to yours - could get -40c on a sunny day, and
