when I started the car this morning, the ext temp gauge said it was 3degress. Oddly, the degree symbol started flashing (not the 3, just the symbol). Ive never noticed this before. Then when I got to work, it was at 4degrees, but the flashing had stopped.
Is this normal? Does it act as an early warning for ice etc? (at sub-zero temperatures, the ex temp display in my mums old Volvo used to warn COLD!, as if you couldnt tell that yourself!)
