Yeah, I'd agree that the temperatures sound normal, so no need to worry. To get a better reading it would be an idea to put VCDS on and look at the coolant temp that is read from the blue ECU sender. I don't really trust the clocks that much. Mine sit between 80-90 degrees coolant, with a lot of variation, and 95-110 degrees oil depending on how hard you are driving.
The problem is that there are simply so many parts to the coolant system - radiator, water pump, auxiliary pump, thermostat, fans etc. - that it's hard to pin point something without replacing the lot.
I get that VW might have changed the thermostat to regulate the temp by restricting flow to a different base temperature, but I can't see it being that accurate, and I'd say on a VR, once the stat is open it stays open and temperature variations are controlled by radiator airflow and the fans, but I could be wrong.
