I'm just parroting what I saw on a VW forum while trying to educate myself about catch cans, and I still have a very foggy concept of exactly how a turbo system functions, so forgive me for being no help whatsoever.
Is it a direct injection motor? Is it possible you're getting some blow-by which is pooling overnight then getting sucked into the turbo when you first start it? I was reading a thread where people were trying to redesign their PCV systems to dump the oil to the ground or run it through a catch can, and someone who sounded much smarter than me explained how that would mess with the vacuum and still cause oil to collect in certain situations. :dunno:
