wat i'm surprised is that we both have an MY17 model, same battery part number, however manufactured at opposite ends of the world!!
mine is Banner - 6R0 915 105 B - Austria
his was Sebang - 6R0 915 105 B - Korea.
with regards to the newer battery, and different part number - yes, most likely one that superceeds the old 6R0 battery.
with regards to the size - my understanding is that the Passat B8 also has the same spec battery.
