There have been story's about the crank case valve freezing and causing engine damage. BMW offers a cold crank case valve kit for this problem. Water build up in the valve can freeze, then pressure builds up and blows the oil cap off or more. I have read about valve covers coming off over this. You did the right thing by shutting off and letting any warmth set in. It's good to just let your baby warm up before driving off.
