Thanks for the update, the oil consumption and dpf blocking sounds very much like my XC70 euro4.
I came to the same conclusion re turbo, but (still) haven't got round to changing or replacing the core yet! The dpf blocking has been reduced by drilling a few 20mm holes asymetrically through it, but the side effect is the smoke is visible :-? my plan is to sort the turbo and if that sorts the oil/smoke problems then I might look at the lifters and followers to remove the occasional chug-chug sound!
