Coolant/Washer Level Sensor (installs in expansion tank) - Many BMW (see list) (more info)
This is the sensor / sending unit that notifies the computer if your coolant level is low. When this fails, it can give a false indication of low coolant -- or worse, not inform you of a low coolant situation which could potential cause overheating. (Note: This sensor is also found in the windshield washer container, to alert the computer when you are low on washer fluid)

This sensor also serves as the washer fluid level sensor on many models.

This fluid level sensor is found on the following BMWs:
