so a off the shelf 10w40 semi synthetic is NOT acceptable and
there are many if not all oils that meet BMW LL01 that are not 10w40
ALL OF THEM ARE FULL SYNTHETIC and meet the
ACEA A3 B3 - A3 B4 specification as well as the BMW LL01 specification
i would contact BMW direct
OR
look in the BITOG forum in the European section to clarify exactly what the minimum oil specification for your car really is and never use an oil that does not meet that specification .

The oil meets the relevant standards as required by the owners manual.
