Junkie, you've been posting this many times on this forum and audiworld. I think you are posting junk. Audi PS systems are very sensitive and I wouldn't play. Mobil 1 ATF is too thick for the winter, and if a 'weak' additive package concerns you, flush it often. I flush mine twice a year with 11S, during my oil change // 13 years and no leaks so far.
