When it was cold my car told me it was -18.5 degrees outside. This was a month ago and in the UK. Now it is hot my car is telling me its 30 degrees outside. I know for a FACT its not and when I drove around and the body work cooled down the temperature display went up.

I have a GT and I believe the thermometer is in the wing mirror.

How much is a new one? can I do it myself? can I reset it? does it need a new ECU/Body computer? Does this happen to anyone else?

I suppose it does not matter a great deal other than when it is cooler the 'ice warning' indicator comes on which is slightly annoying.

Any advice very welcome.
