Anyone follow the "ECE model codes?"

Clearly 337 must refer to the M sport package since we know wheel style 223M and 333M go with that package...but what is ECE model code 330? Maybe the wheels for the other, non-M sports activity package?

Unclear to me from this chart which we might expect to see on the diesel.

Also, while on the subject of the diesel has anyone seen any hint as to whether the M sport package might finally be an option on the diesel in north america? European photos obvioulsy dont tell us much I guess. Seems to me if >30% of X5's sold in NA are diesels lately BMW might do well to include all the option packages.
