You should also be aware that the dash display is notoriously inaccurate and nonlinear, so “splitting hairs” over where the needle sits is a waste of time. You should look at the dash gauge as telling that the car is either “hot” or “not hot”, and nothing more…..

I'm not using the dash display, though once you learn it, it's not that bad at all, you just need to know how to read it. I'm using the climate panel to read the actual coolant temp via the hack / codes.
It's really hard to be sure re the operating temps. All I know for sure is that it's fine when cruising and that the fans operate normally and cool reduce the temps as before. What with variable conditions (it's summer now, so higher ambient temps), I may be imagining things. But I don't think so.
