I have had it come up three times...I now have the warning light..and I just got back from the dealer after having REPLACED THE BRAKE PADS in the rear. I have an Alcon BBK in the front...but it has lots of pads left. It is definitely a quirk with both the E90 and E92 335 cars..this happened on mine BEFORE I installed the BBK on my car.
