My F30 did this and from what I understand, the F2X chassis does this as well.

The tail lamp harness has issues which causes the tail lamp board to repeatedly burn out. If I remember correctly, BMW has a TSB to clip off the old harness and solder in a newer, reliable one.

Mine got so bad that it would be double flashing for days at a time, and the car would go "gong" with the alert message the first time I use the turn signal of each drive.
