I haven't messed with my N55 too much yet, so I don't know the similarities on it. But is there oil all in the charge pipe? I had a similar situation with my N54, where I had tons of white smoke coming out of my exhaust at a stop. Of course, everyone diagnosed it as blown turbos. Turns out the plastic oil/air separator that goes from the top of the engine to the charge pipe wasn't working and it was leaking oil all into my charge pipe which was getting shot into my engine. It became worse over time. I replaced it with an oil catch can, and the problem was solved. No more oil in the charge pipe, and no more white smoke out the exhaust.
