so I called the parts guy at BMW just to ask about the 21 torx bolts on the tranny pan, and he told me that they arent one time use...at the same dealer 2 weeks ago the service guy who did a quote for replacing the gasket told me that they ARE one time use... confused now...the parts guy said normally its indicated in his manuals if a bolt is one time use, but maybe the service guys heard of some kind of bulleting stating that these bolts have problems?
