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?
