Right I'm gonna start by saying sorry for any arguements this causes :grin:
I'll also apologise as this is my first turbo'd car and I'm not used to all these little valves lol
there seems to be 2 schools of thinking on this :
1 block it off and be done with it
2 add a catch can and drain regularly
which is the better option for say stage 2+?
Cheers

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
