Mine did last week, and all the indications were the rectifier or the alternator (engine just died after a 25 mile high-speed run, clock reset itself, horrible death rattle on the starter, battery not charging etc). I was not a happy camper, especially as the alternator is only 12 months old. Turned out the polybelt had split, despite being changed 10,000 miles ago. Not sure what the moral of all of this is but at least BMW have dealt with the replacement costs as a warranty job!
Maybe you had earplugs in your ears and up your nose
