I can't answer with specific knowledge of either this engine or this model, but what you describe here in this quote pretty much matches my observation of the regen process on my 2014 V60 with the newer VEA engine (also using the Car Scanner app)... i.e. the soot loading never went down to zero but would stop at an inconsistent (but low-ish) figure. I assumed that it was an 'economy' thing to leave something that hopefully passive regeneration would then deal with and so minimise the active regen burden?
