The sensor allegedly measures oil level, not the life of the oil (a function of your driving cycles, mileage, etc. ... mine wanted a 20K oil change). I say "allegedly" because I intentionally under filled my first change and it still indicated full. It's never indicated anything but full. I would love to have a dipstick. For now, one on them (BMW will change on service indicator OR one year), one on me.
