I have an annoying intermittent fault.
Sometimes, usually when it's hot, I turn on the car, but the outside temperature display on the dash shows a minus reading. E.g. -22, or even -35.
When this happens, the climate control stops working (understandably) and it's really hot inside the car.
When it shows the correct temperature, the climate control works really well.

Does anyone have ideas what could cause this problem and what it need to do to fix it please?

Many thanks in advance
