Smart opener only works in conjunction with comfort access (option SA322). F10's with comfort access from model year 2012 (built late 2011 onwards) have smart opener as part of their comfort access system. Cars before model year 2012 with comfort access did not have the smart opener feature.
Smart opener cannot be ordered separately. It's included with comfort access. For this reason you will not find it listed as a separate option code.
Smart opener is not related to powered trunk lid (option SA316 automatic trunk lid mechanism). That refers to a motor opening and closing the lid. Smart opener is compatible with both motorized/un-motorized versions. In the powered version the lid opens slowly with a motor, without option SA316 the lid springs up without motor assistance.
