Took my 2006 4.4 in Wednesday for:
1) Hesitation
2) Gait Rattle
3) Driver's Seat Belt Retractor rattle
4) Nav update
5) Pulsating idle w/o AC on

Still don't have it back. BMW regoinal involved.
SA says, will keep it until all can agree on engine/trans problem. I have no clue other than this, I will update Monday or Tuesday...
