SURE! I never said there was no coolant sensor. I am sure BMW uses one or more coolant sensors - so that the engine ECU can regulate coolant temps. I am also sure in each SW update BMW has changed these specs for the coolant temp regulation.

What I am saying is there is NO mechanical old school thermostat that opens and closes via temper'd/metal spring - like say in an e36 or e46 car.
