How to diagnose it step by step
- Read soot load.
- Check other codes (EGR, turbo, injectors).
- Run a forced regeneration if the load allows it.
- Clean or replace the DPF otherwise.
How to fix it
If soot load is moderate, a forced regeneration fixes it. If it's very high, the DPF needs cleaning. Also fix the cause of excess soot so it doesn't recur.
