This is the oil I recently got the dealer to put in my Golf.
Castrol has upgraded there 5w40 weight with Castrol Edge SPT 5w40 which is now BMW LL-01 approved and has 501.01 for another new approval list for the new Audi R8

They are all nice specs, but they fall well below the 504/507 performance threshold. Unfortunately, these low-saps oils don't work well w/our US quality fuels.
I don't see any thing special here.
German Syntec is unique chemistry, and one of a handful of thicker 30 weights that make the A3 spec, instead of the typical thinner USA 30 weights that make A5 spec. Same "quality" just thinner, which is a good thing!
Mobil 1 0w-40 is about the same as Syntec 0w-30 in the cold.
I'm using some old M1 0w-30 SL.
The new 504 spec oils are all 5w-30, fwiw.

Looking over BMW LL-01 and LL-98, there is a substantial jump in performance.
However, when you overlap MB 229.3, which the OLD Syntec 5w-40 already carried, plus VW 502, you see the addition of BMW LL-01 adds nothing more than a paper stamp.
GM LL-025-A is a helava spec.
As you can see, there isn't effectively a difference in the specs, when one oil meets them all.
