Hi, I have recently been having a temperature gauge problem

Customer Question

Hi, I have recently been having a temperature gauge problem on my 1999 Volvo S80 2.4 auto. The gauge will either move up a couple of bars after driving for3-4 miles and stay there. Or it will shoot straight up into the red. I know the car is not overheating as I can turn it on in the morning after being switched off all night and it will go straight back into the red, left idling for a few minutes it will fall back to normal. Them cooling fan will come on when it shows red on the gauge but switches off when it goes back to normal. I have had a new engine temperature sensor fitted, the thermostat is working fine (checked by garage) and the ECU is reading the correct temp but it's not getting that info to the gauge. When this happens the emission service light comes on. Any ideas?
