Here we go.....
Everything is Ok there is no pipe needed for there.

just ignore it - its correct there is no pipe connected to it its the wastegate cap.... the turbo is on the end of the rubber hose coming from the airbox (just to the left of the wastegate in your picture)

ahhhh ok that makes sense, i have seen old rally quattros with a pipe running off it with a little inline filter on it too...

[GirlRacer]

Don't run a pipe from that take off to vavuum, especially without a one way valve. On WOT, boost will probably approach 2 bar (or more depending on your turbo spec), as the WG diaphram will be kept shut.

I did try it once, and the car certainly scrabbled for grip on a gravelly road as the boost came in with a rush, but it hardly tailed off at high RPM. Nice, but I doubt the engine would have lasted long with that set up.

On 10V engines with no DV, vacuum is used to assist the opening of the WG diaphram - the cap is connected to the AFM via the top cover (duct)
