BMW just revised the SIB and added new part numbers for the front tension strut. I don't know whether the new parts (31 10 8 854 993 and 31 10 8 854 994) are available yet, but they will probably supersede the old parts (31 10 8 854 989 and 31 10 8 854 990). Both the old and new parts are suitable for fixing the crunching noise issue though.
