First off, I have searched both this board and renntech and there seems to be a bit of confusion on whether to use the Dex-cool (OAT formulation) compatible product or the HOAT formulation (Zerex G-05, etc). I perused DJ's post where he showed a pic of the G-05 he swapped in after making the mistake of using the plain old green stuff, but the Renntech thread clearly stated to use Dex-cool and the Zerex website recommends Dex-cool for all VW, Audi, and Porsche applications after 1996.

So, which is the correct coolant for those that know?
