I CONTACTED MY SERVICING DEALER AND EXPLAINED THE PROBLEM. HE STATED HE SEES THIS ALL THE TIME AND THE COST TO REPAIR IS $324 FOR A NEW RDC MODULE + ONE HOUR LABOR + TWO HOURS TO REPROGRAM. I REMOVED THE RDC MODULE AND FOUND EXTREME MOISTURE DAMAGE AND MELTED PLASTIC NEAR THE CONNECTOR IN THE MODULE. IN THE ATTACHED PHOTO, I ATTEMPTED TO CLEAN OFF CORROSION. AFTER MORE RESEARCH I FOUND A BMW TRAINING MANUAL DESCRIBING THE MODULE AND IT STATES THE MODULE IS WATER-PROOF.
