Neither one is right. You want the Castrol Syntec 0W-30 or the Mobil 1 0W-40. Both of these oils meet the BMW LL01 specification. Castrol Syntec 5W-30 and Mobil 1 5W-30, both as sold in the United States, do not.

Or of course the BMW 5W-30, which while it comes from Castrol is not like the 5W-30 that we buy at the parts stores.

If it were me I would not panic, but I would change it much sooner than the CBS calls for.
