What is this part and why does it matter?

The catalytic converter/diesel particulate filter (DPF/FAP) reduces harmful emissions — the catalytic converter chemically converts pollutant gases, while the DPF physically traps soot particles from diesel exhaust.

Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Failed emissions test
  • Check Engine light with a catalyst efficiency or DPF-related fault code
  • Reduced engine power or a rattling noise (broken internal honeycomb structure)

Installation information

Requires cutting or unbolting the old unit, and welding or clamping the new unit into place with new gaskets at each flange connection.

Frequently asked questions

The internal ceramic honeycomb structure can crack from age, physical impact, or contamination (like unburnt fuel from a misfire), and the broken pieces rattle inside the metal housing.
