First of all, thank you for your work. I bought the APP, cofigured it ( which was a little bit tricky with my engine) and now I'm after first DPF regen.
My car : VW Passat B8 2.0tdi 190KM DFHA, 2017 ( 2018 model year ), 63k km.
After regneration, Soot mass calc dropped to only 25%, 5.93g and why is that? Why it dind't go further to 0?
Also regen duration time shows value 0.
Enclosed my screenshot, I took it fast while driving so unfortunalety there were maps app opened ;p

Is there any manual that describes all values that this is APP is showing? For example, difference between soot mass calc and oil ash residue.
