Customer had front rotors, pads and wear sensor installed and as we know on some bimmers you can reset....front or either rear cbs service on brakes separately. On the 2010 you must reset both because the service counter wont accept one cbs for brakes on this model...I reset the front brakes alone and the service would not clear although pads and wear sensor were new. Rear were good , just thought I would leave this for techs that may encounter this...
