LL04 is LL01 but emissions friendly. It's a Low-SAPs oil which meets ACEA C3 (Low Sulphated Ash, Sulphur, Phosphorus). One thing that does change due to the Low-SAPS nature is the TBN. The starting TBN (total base number) of a LL04 will usually be lower than a LL01 equilivant from the same oil brand. Consequently LL04 oils are only suitable in markets were gasoline and diesel quality is consistantly low in sulphur and ethanol which is why BMW specs its use in only a handful of countries in the EU across all models and only BMW diesels in the United States (I don't know about the UK).
