In USA bauen viele sogenannte oil catch-cans an die PCV´s (Kurbelgehäusenetlüftung zum Ansaugtrakt...quasi die eigene Scheiße solange fressen bis die Abgaswerte stimmen ) um das Öl aufzufangen bevor es in den Ansaugtrakt kommt undd dort alles zubackt und verdreckt. Die Dinger helfen nur bedingt und man muss die auch leeren.
Bei Audi ist das mit mehrstufigen Abscheidern gelöst. Kannst Du im von mir angehängten PDF lesen...
crude oil separation
The crude oil separator function is integrated in the cylinder block. A part of the oil is
discharged by change of direction in a labyrinth.
fine oil separation
The roughly purified crankcase gases reach the cylinder block via a channel in the
cylinder head into the oil separator end module. There, they are first cleaned in the
cyclone separator. decanted oil cyclone oil separator is returned to the oil sump via a
separate channel in the cylinder block. The channel ends below the oil level. A cutoff
valve avoids here that in case of unfavorable pressure conditions, oil is sucked into the
crankcase. If sporty driving (high transverse acceleration), the oil return may no longer be
in the oil, because of the cross fluctuations of oil in the crankcase. Here too, the shut-off
valve maintains the closed oil return. It is the valve anti-rotation guy.

cleaned crankcase gases are conveyed to the combustion by the pressure regulating
valve to a level. The pressure regulating valve is set to a pressure difference
- 100 mbar compared to the outside air. The point at which occurs the introduction
is defined by the pressure ratio of the air supply system.
The decanted oil is redirected to the oil sump via the return channel in the cylinder block.
The channel ends below the oil level.
... ich habe aber ein "trockenes" DSG, welches auch leicht ruckelt, wenn es kalt ist..
