PCV Location 2.0Tdi 140 PDW engine

I'm pretty sure on tdi`s its built into the cam cover.
Do you think it's this?

That's it, apparently there is a diaphragm in there which breaks down or gets holed but its a sealed unit.
 
Apatantly it's a CVC. But does the same sort of thing so I have been told.
 
This is the CVC. But on this model it's built into the rocker cover. You can't replace the individual part. It costs about £160

Ouchhhhhh
 
maybe try just replacing the breather line that leads up to it? i checked it out on the parts data base and it can be done
