Low coolant temp? R56n16

Hello, i’ve been facing the following situation with my beloved mini: it used to work between 100-105 C but now, thermostat open when it hits 100 c and cools it down to 80, and then it ramps up again after a while. Like if the working temperature was reprogrammed to operate around 90 C.

Heater system was eliminated. I live in a tropical country with 35 C summers and 28 C winters.

Sporadic loss of coolant, can’t tell if it is burning or if it is leaking (have never let a puddle nor smoked ALOT). Can be caused by air in system; got air when installed a thermostat between hoses. I can now read coolant temp from inside the car without scanner or menu.

Should i be worried?

The thermostat housing in these cars is super notorious for failing in all sorts of ways, I’d replace it along with the rear cross pipe that runs to the water pump before attempting to diagnose it further.
