sup all, I have a wierd issue, on the very cold mornings where there has been ice on the car, i start up the car the temperature warning comes on. so far what i've been doing is leaving it on for a minute or two then switching the engine off then back on again. the temp warning does not come on again. I can only think that maybe there is ice on the contacts and once the engine is warmed a little it melts and comes off. anyone else heard or seen anything like this? is this something i should get checked out?
