Decided to go with Liqumoly's Molygen 5W40 this go around out of interest so did a VOA to compare with their Leichtlauf High Tech 5W40 which I have also posted a VOA for previously but have included here. The Molygen should be basically the same except in contains a friction modifier (MFC - Molecular Friction Control) which is supposed to be a chemical friction additive (doesn't have the solid bits like MoS2 or Ceratec) made up of tungsten and molybdenum and of course, the green "predator blood" color. Side by side they look nearly the same otherwise and the likely missing VW502 00 approval is probalby due to the friction modifier included in the Molygen vs. running Ceratec or MoS2 separately which also would negate the VW502 00 approval. So a spike in molybdenum is all I see that stands out. Viscosity is nearly the same. TBN wasn't run but again, should be basically the same.
