The interesting part of this is the F10 forum has this issue fully documented and BMW has a fix.
Same engine. Guess F10 does not talk to F07?? Different cubical??
Sun or shade makes no difference with mine and it occurs daily.
Someone noted that they will attempt to get a video, great idea and I will make that happen before next visit to dealership.
Never hurts to have hard evidence.
