How do you get the clock back into 12 hour mode from 24 hour mode? Resetting the time and hitting the 1000 button does not do it. It still reads XX:XX HOUR (with the correct time in the X's.)

I am pretty sure I have done this in my prior E34's but I am stumped this time. I can't find it in the manual either, only how to change from AM to PM.

Also, the center console display functions on my steering column stalk do not work. Nothing comes up when you press it in. I have tried to reset according to the manual.

A while back the OBC lights went out, although you could read them in the dark with the headlights on. Before I could replace the bulbs, it started working again.

Minor irritations on an otherwise problem free car, but I would like to get it sorted out. Thoughts?

TIA,

John
