Signs Your Diesel Oxidation Catalyst (DOC) Needs Replacement

  • Inability to initiate or sustain passive or active DPF regeneration cycles due to low catalytic temperatures across numbers 2131526 / 2088094
  • Visual signs of face-plugging, oil contamination, or unburned fuel soot accumulation at the internal element face
  • Active dashboard diagnostic trouble codes (DTCs) signaling low catalyst efficiency levels or engine backpressure spikes
  • Unexplained increase in downstream DPF loading frequency due to loss of upstream catalytic conversion efficiency

*Note: Always verify exact vehicle compatibility using your vehicle's VIN number, emissions family descriptor tag, or the original stamped part number on your catalyst unit casing before placing an order.
