I've searched on here, AW, and VWvortex, and even googled the appropriate ATF P/N for my tiptronic. Unfortunately, I'm getting conflicting info. Some say G 052 162 A2 is the right one, but some say G 052 990 A2 is equivalent to G 052 162 A2 and is used for newer tiptronic transmission. Which one should I use?

I would greatly appreciate your input. TIA.
