There were no clear answers either about google. Does anyone know which types of transmission oil were fed into the gears of the ALL or ANV in the years 1999/2001? 1. Was the VW G 501 50 used at that time? 2. Is this still valid today? 3. Or is there a new specification from VW? 4. If yes- what is it? 5. Should there be a new specification of VW- is it equivalent to VW-? the VW G 501 50 (so only a renaming)? I would be pleased to answer the questions 1-5. Thank you already once and Many Greetings quali
