Wow, 1 out of 3 EVER to have this happen, for reference:
PuMA is a worldwide BMW database of all reported problems and most with the their appropriate fixes. The acronym means Problem and Measures management Aftersales or in German: Problem und Mebnahmenmanagement Aftersales.
Sorry OP you had to be one of them, sound like quite the ordeal. Hope they sort you out sooner rather than later.
