HUD would not come on for me just last night. Looked it up and it brought me to this thread.

Drove home without HUD. Stopped the car for about 5 minutes. Started car and HUD came back.

Not sure if just coincidence or what, but all these little things happened AFTER my seat repair.

Brought my MY16 X3 in for a driver seat ripped leather repair (just above the hard plastic seat controls)
-Seat repaired.
-Picked up car and as I got in, I see an "air bag malfunction" message.
-Had to leave the car overnight again since technicians were all gone.
-Told me my 3yr old car's battery is dying and needs replacing; and that was what was causing the message, a dying battery.
-Sucked it up and told them to replace the battery.
-A week later, reversing out of my driveway I get a "reverse light malfunction" message. Drove to my destination. Parked. Checked vehicle info...message still there. Did my errands. Came home; no message; checked info, nothing. Had the wife video me reversing, all good.
-Now, the HUD glitch.

I also remember another time my HUD was working, but the navigation info wouldn't show up. After an engine off and on, everything came back.
