Hi guys, I just recently purchased a new-to-me 2013 Passat TDi with the DSG (tiptronic) trans. I'm a huge LubeGuard advocate and use the stuff in all my Auto Trans vehicles with great success. However, the DSG trans is a different animal with no real torque converter and duel clutch setup. It also uses a very unique fluid. Is it safe to use LubeGuard Red in this and have any of you VW guys done this successfully?
