BMW 328i Coolant Level Sensor

The Coolant Level Sensor in BMW 328i vehicles is an electronic item used to detect the level of coolant contained in the system of automobiles. For instance, this sensor is used in associating low coolant levels with alerts to drivers before any possible damage to the engine takes place. At times, a Coolant Level Sensor may have a problem and does not make the coolant level light blink upon starting the car; hence one may be safe when actually, he or she is not. Thus, it is necessary to check whether the Coolant Level Sensor is working or not to diagnose the general status of the car.
