There is one at each wheel. The car needs one for each wheel for ABS and anti-spin stability control. They go for about $65 each, which is not bad.

You can see them if you drill-down on the "front axle" and "rear axle" diagrams here (http://bmwfans.info/parts/catalog/E64/Cabrio/USA/650i-N62N/LHD/N/).

You might be thinking of the brake pad wear sensor if you only saw it on the front driver's side. There is a front left and rear right brake pad sensor (2 total) but 4 speed sensors.
