I am having a weird problem, as some of you know that the climate control display can display the sensor values and information about the car, well when i set it to #51 (coolant temperature) in real cold climates like this week, we get to -30 C it shows 27 degrees and then starts to increase only after 27, but sometimes it does show the actual temp like -20 or whatever and then increases from that to 90 C. Is that something any one is familiar with. And it is particular about 27 had that happen 4 or 5 times already.
