Check out the PCV Playlist if you haven't seen the original few videos yet, as especially the first one is vital to understanding what is going on inside:
• MK7/MK8 PCV Tech Playlist
In this video, we'll go over some observations on data obtained from people who have also also done the retrofit. There are some key differences in certain MK7 PCVs like the original AH version (and I assume the BM and AP as well, which I have not cut open just yet) that need looked at further. We'll dive a bit deeper in the PCV function to make sense of some root issues, and try to understand just WHY the "full" retrofit may be necessary to have better results.
