Second hose going away from the camera, prob 3/8 hose.
Goes into the inlet of the turbo bit seems to have some kind of valve on the end? Maybe a one way valve? It's a strange fitting, it's loose as the hose tail wobbles if pulled but can't be tightened up in side the metal part.

Have a boost issue that I can't resolve and while looking for boost leaks I found that fitting is loose, could maybe suck in unmetered air.

Any one know what it is/what it's for

Cheers

I may be wrong but that looks like the Tube - Vacuum (part code 1371605) This would be leading to the boost solenoid but this is just by looking at the parts catalog on 7zap

It's the Crankcase Ventilation hose. There's a NRV at the end.

Any one experienced these leaking?

The hose tale seems loose where it goes into the threaded part and I have oil mist in the area, wonder if it could leak at times or even suck in air.
Would explain hesitation/ slight coughing when coming on boost, especially when cold

Cheers
