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.
Does this replacement unit come with the necessary clamps and gaskets?
It depends on your selection. Selecting the "Full Kit" configuration adds the listed service gaskets and hardware clamps to your shipment package. Opting for the "DOC Only" selection provides the replacement core unit alone without service mounting hardware accessories.
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.
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 A6804901314 / RA6804901314
- 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 OEM part number on your catalyst module casing before placing an order.
Disclaimer: Product images are for reference only. Service installation hardware depends on configuration parameters selected during product checkout lines. Selecting the "Full Kit" option adds the explicitly listed high-temperature gaskets and hardware clamps to your tracking shipment. Price is for (1) pre-packaged DOC component setup.
