Well, mine if you are crussing normaly sits around 85/90ºC then stopped in traffic it goes to 97ºC i would think, then the fan kicks in and it goes back to 95ºC around that. The strange thing is that with the laser temperature gun, the pipes are normal like 90ºC.
I did the headwork and headgasket because it had to much pressure on the cooling, so i would expect to be normal now... the pipes are not rock solid after that you can press/squeeze, they are a bit hard but you can still press on it. I've changed the radiator too the fans are kicking at the right temperature.
So I would say that is a dodgy sensor ? or gauge ? Or something else ?
