Best option is to get the last revision OEM PCV.
The TFSI was designed to run with a PCV system so it's not going to do it good having all that crankcase pressure in the head, so blocking it off isn't a great idea.
Catch can doesn't do much for the TFSI, the oil which gets on the inlet valves will still get through the turbo seals so the catch can is a bit of a waste of money IMHO. VRSAlex (admin) proved that after 8k miles that his valves were dirty again.
I looked into it, read everything on the forum and decided to stick with the OEM PCV
