Noticed a few days ago that my dash was showing an outside temp that I was sure was lower than the real temp. It was showing -1 degree, but it was pretty mild that day, prob around 5 degrees. Usually on a cold day it'll creep up by 1 or 2 degrees after a few mins of driving but not this time. Following day it was showing -2, then crept up to -1, again defo not that cold on that day. Today it stuck at 1 degree all day but it was about 5 degrees according to the weather forecast, a fact backed up by my testicles not retreating in to my body.
It's always been accurate up until now.
So quite simply, is it likely that the sensor is gubbed and will need replacing, or something more simple? Perhaps disconnecting the battery to reset the electrics?
