SIGNS YOUR DIESEL OXIDATION CATALYST (DOC) NEEDS REPLACEMENT
- Frequent, unprompted, or incomplete DPF regeneration cycles linked directly to upstream catalyst efficiency degradation matching part numbers A035H582 / 5287522
- Excessive particulate soot face-plugging or heavy face mask scaling across the internal catalyst face assembly
- Active dashboard diagnostic trouble codes (DTCs) pointing directly to poor catalyst conversion efficiencies or thermal response delays
- Unexplained commercial engine backpressure spikes or noticeable horsepower deterioration under loaded transport pulls
*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.
FREQUENTLY ASKED QUESTIONS
Does this replacement DOC require a core return?
No. This is a brand-new aftermarket unit. There are no core charges, core tracking hassles, or return freight expenses required.
What is included in the Full Kit option?
The Full Kit includes the primary MN0406 diesel oxidation catalyst core along with the necessary service components: two (2) high-temperature replacement gaskets (2871453) and two (2) heavy-duty exhaust clamps (2871863) required for a complete install.
Will this unit clear active dashboard emissions fault codes?
Yes, assuming downstream diesel particulate filters and exhaust sensors are operating within specification. Replacing a degraded catalyst restores legal conversion thresholds, allowing the vehicle control module to clear active DOC efficiency faults.
