I heard twice your cold start cycle , once in your first video and once in your last video...
And I heard and saw twice your your problem only during the cold start cycle .
Personal I think your problem is in your cold start cycle .
After the cold start cycle it sounds fine ..
Personal I would take the car to a BMW/Dealer ASAP , because this sounds not healty !
