Can I just ask, what is the PCV and what benefit do you get for blocking it off? Is this for the petrol or diesel engines? Thanks

PCV valve on the 2.0T engine. Its the second weak spot (second to the DV)
on these engines. The failure seems more common on chipped (stage2) cars,
but even stock cars have had these valves fail. When the valve fails,
you’ll notice your max boost PSI slowly declining (over a cpl days, weeks,
it will get worse) and eventually you see signs of oil being blown out the
oil fill cap. This is because the stock PCV valve is failing under boost,
and allowing pressurized intake air back into the valve cover/crankcase.

You could do the PCV block plate from BSH.
The OEM parts in the picture above from Peugeot are marked with part number on the bag. Call and ask.

Yes, should do it. But i have not tested it myself so can guarantee they will fit.
Do some more read up on the PCV valve over at the golfmkv forum.
