Not sure, but my 650 was a May 2006 build and
has sensors, which I determined after much confusion at the service dept. of the dealership--even after giving them the VIN several times. They continued to claim into Sept. that the VIN is not reliable when trying to determine if sensors are installed. Hard to believe. when I ordered them for my winter wheels, they took a week or two to arrive. Apparently there is relatively little demand for replacement sensors.
