I have an issue with the display (radio station , date time,mpg) that gives the tempreture reading outside as it states it is 150 degrees . Can i reset the whole system? Do ineed to run it through diagnostics? as the garage want to charge £41 or Can i repair myself?

Hello sparkyfarm

The outside air temperature is taken from the sensor in the wing mirror and fed directly to the BSI computer.

There is a forum post about the temperature sensor on a Citroen C3 here, with some nice pictures of the sensor and its location in the mirror.

You could try a new sensor, as the only other thing you could do yourself is reset the BSI computer.

Thank you very much for your help. I will check the sensor.
