E83 with Nav/DSP - Comfort Functions Not Working

[E39NLA]

2007 X3 3.0Si with Nav and DSP. Comfort functions for turn signals and auto-locking are not working. Auto-unlock does seem to work. Other ibus functions (e.g. Steering wheel controls, display, temp readout, etc) work fine.

Ted, let me know what you need me to do with the TTY and I'll send you a log.
