DPF Diagnostic- difference between "load state" and "soot content"


Active Member

Carrying out diagnostic on my E320 CDi (W211) using Delphi software I get 2 readings of real time data for the dpf.

One is for "soot content %" which I understand and the other is for "Load state %" which I am not clear on although I assume that it refers to the ash content in the dpf.

Does anyone have the answer?
