The thermostat on the BMW maintains optimal engine operating temperature by opening to allow coolant to flow through the radiator and closing to keep coolant flow restricted to inside the engine. Failure of this thermostat can cause your engine to run too cold if it is stuck open or overheat if stuck closed. In addition, being that the thermostat is electronically monitored, if your vehicle’s engine computer detects a problem with the thermostat, it will lock your BMW into limp home mode and turn on the check engine light.
