I replaced the car's Bluetooth ULF (gen 5) with the latest (gen 13) one and everything is working well now. I suggest checking your ULF part number against this list to see how out-of-date it is. BTW, don't believe that list about newer parts not being available from BMW dealers - I got the latest 84-10-9-154-358 ULF from my dealer for $375 (Bimmernav wants $599).
