Pull the hose off the intake pipe (pcv rocker to intake pre turbo) and have a look at the amount of oil in the fitting. All modern engines breath blow by oil into the intake (emissions requirement) rather than breathing out to atmoshere. This oil degrades the boost hoses and congeals in the intercooler and will eventually reduce the flow of air though the intake.
Hence Provent, it filters the bypass air and you either plumb it into the sump or once a month drain the oil out of the provent.
