You are going to need to change the sensor. The E90 version has two wires, with the first one wearing through early in order to give the CBS a data point for predicting wear/remaining life.
As for the orginal questions, 72,000 miles on the rears and 99,000 miles on the fronts. Only 30% (+/-) highway driving, but a manual transmission.
