What causes this (Oil at Turbo Inlet)?

PCV will do that. If you want to avoid that you can put an oil catch can in and that will take care of the oil going through the intake. The other possibility is a WAY over oiled air filter if you have the cleanable oiled filters like a K&N. If that's the case however, I'd be very suprised if you're AFM is still working with that much oil that far up.
You really have three choices...
Install a catch can, or
leave it like it is and quit looking in your pipes, or
run the engine without oil.
I would only recommend one of the first two options. The 7M PCV system is supposed to return oil vapors from the cam covers back into the engine through the intake to be burned. What you see is the condensate from the vapors as they collect on the relatively cool surfaces of the intake tract. It will inperceptibly reduce the efficiency of your intercooler and slightly increase the rate at which carbon builds up in the combustion chambers. Other than that, it is a non-issue and appears perfectly normal.
