When to bring it in
- DPF, DEF, or SCR warnings
- Frequent forced regens or a derate
- High soot load after a recent cleaning
- Visible exhaust leaks ahead of the filter
A DPF light is not always a bad filter. We check regen history, sensors, the doser, and exhaust leaks first. When the filter is loaded or damaged, we clean or replace it and confirm the system can complete a regen.
