Hey, Ibiza cupra 1.8T BBU engine.
Smoke coming out of the exhaust mostly after downshifting within lower range of RPM (1500 to 2000).
Lets say I am cruising at 5th gear, letting the car slow down by itself, downshifting to 4th, stopping at red light, pressing the throttle slightly and white smoke coming out of the exhaust.
Thats what happens most if the times, and sometimes on the downshift itself.
What can that be?

PCV
Turbo
Valve stem oil seals

I'd start with the PCV.
Just replaced the PCV a few hours ago, altough the old one didn't seem faulty (wasnt stuck or anything or had any dirt)
Didn't drive the car yet, I'll update soon.
