Ditto for question #4 (plus more). The 20 digit alpha/numeric display on the instrument cluster actually has first priority to the Check Control system (warnings). The ability for the OBC features to appear there is an added benefit and have to be "programmed" to appear in the instrument cluster display. The dedicated display for the OBC is either the MID or the Nav monitor (which ever you X5 has...of which you didn't mention your set-up).
When electrical power was disrupted (for your install)...the OBC features now need to be reprogrammed (probably along with a few other things like your clock). You can program ALL the OBC features to appear in the cluster display...or you can select specific ones that you prefer (I only use TIME/DATE/CONS1/RANGE/STOPWATCH).
Again, since you didn't mention any specifics as to what set-up you have...the instructions for the MID are below. If you have a Nav screen, you can probably figure it out by extrapolating the instructions from below...just substitute "Nav monitor" for "MID". If you get stuck...then turn to your Nav owners manual for instructions on how to program the OBC features into the cluster.
