2011 definitely has a smart alternator but the battery light won't illuminate unless the alternator or the LIN wire is faulty.
Before chasing a replacement diode pack for your old alternator check that none of the insulation on the windings is a darker colour than the others indicating that the windings have been overheated, such as occurred with my L322's alternator.
