i have a high temperature in my car as well, i don't get the overheating message but when i see the temp via hidden OBD it going between 90 deg to 105 deg but when i open the heater with the highest temp, the engine temp go down to 77 deg, so i don't know if the problem is from the temperature sensor or from the thermostat or from something else??? the fan also is not working when the temp go high.

Diesels should run at 90 and petrols run hotter
