5 minutes into my drive home I realised the temperature gauge was at 12 o'clock, the red light on and the "High Temperature" message. A few seconds later the message disappeared and the gauge dropped instantly to normal 9 o'clock, and stayed there for the rest of the journey, about 15 minutes.

A blip? The initial signs of a failing thermostat? Any ideas?
