Now that the cold weather is upon us, I think my outside temperature sensor is playing up. I had the car out for a run yesterday and then stopped off at the shops. When I got back into the car, the temperature display was +20 degrees. When I stared driving, the temperature slowly kept dropping down till it reached +5 degrees. I do think that was about the right temperature. Today it did the same thing. Temperature starts really high then steadily drops down till it reaches what I think is the correct temperature. Has anyone else had this problem?
