yes mate, that should be a one way valve. you can replace the whole thing with the vac lines for around £30 ish.

1K0612041GM supercedes the older part and now comes with the surplus vac outlet.  It's a vac feed for engines with mechanically actuated intake flaps.

You used to be able to buy blanking caps from VW, but not sure you still can.   I would just cut it off flush and plastic weld the hole over.
