Skoda superb exterior temperature sensor

[Steve1569]

Hi guys, I am after some help and advice.  My external temperature is reading 14oC when I know its at least -1. I have replaced the temperature sensor hoping this would fix it, but it still reads roughly the same.

 

This happened after we drove through snow and sleet a few weeks back. It was working fine and then started to glitch after the journey. 

 

Any advice would be appreciated. I have read some of the other threads but it doesn't cover this persistent fault.  My nearest skoda garage is 3 hours drive away.

Sounds like water could have got into a connector in the sensor wiring?

Possibly, I have got the car booked in next week to be plugged in to a computer to see whats occurring
