hello, here in Baltics we have item 0Y3 and 8Z7 set in car standard specification.0Y3 "Cold zones"
8Z7 "Cold country"
For most VW models these Prn codes forces factory to add the strongest battery and genernator to standard specification
You can see both Pnr's in boot on a paper at the left of spare wheel.
Anyhow there is no Pnr NY1 "Incrased battery and generator capacity" available from factory for Up!
