It was pretty cold this morning like 10ēC. Exterior temp. on the screen showed 15ēC no freeking way! anybody else notice the inaccuracy?

 

Did it eventually drop to 10, or stay there on the whole drive ? The sensor will be situated somewhere behind the front radiator grill, (probably the lower one), and the connection could have been affected by salt solution over winter.

 

10 degrees C in the morning? Cold?

 

It's cold if you live near the tropics. Shudderingly cold.
