By the ECO Technical Content Team. This guide was prepared from ECO application tables, OE-reference data and the official technical sources cited at the end. It is written for distributors, fleet maintenance teams and parts specialists. Product selection must still be confirmed against the vehicle serial number, engine/aftertreatment configuration, dimensions and current OE service information.

Why this subject matters

A European DPF catalog can include the same manufacturer across trucks, coaches and city buses, with changes at model-year or emissions-generation boundaries. ECO’s list spans DAF, Iveco, MAN, Mercedes, Scania, Renault and Volvo applications and therefore needs a consistent shortlist process before a number is quoted.

A diesel particulate filter is not an isolated canister. It sits in a thermally active system that includes inlet and outlet cones, sensing ports, dosing hardware, brackets, clamps, gaskets and control logic. The US EPA explains that a DPF traps particulate matter and periodically regenerates; the service implications include backpressure monitoring and ash cleaning whose timing depends on device design and duty cycle. Consequently, a correct catalog match has to preserve both filtration function and mechanical sealing.

Start with manufacturer and platform

Typical search anchors include DAF LF/CF/XF, Iveco Eurocargo/Stralis/Trakker, MAN TGL/TGM/TGS/TGX, Mercedes Atego/Actros, Scania L/P/G/R/S and Volvo FH/FM/FE/FL. Bus applications should remain explicit because packaging can differ from a truck carrying a related engine.

Use catalog examples correctly

Examples from the supplied list include DAF references such as 1I001, 2A000, 2A003 and 2A005; Iveco families such as 2K000, 2K002, 2K010 and 2K014; and MAN references beginning with 4I. These are discovery keys, not blanket promises. Each must remain tied to its OE and model row.

A repeatable verification workflow

1. Capture the source record. Record the full OE number exactly as shown, including prefixes, suffixes, spaces and remanufactured designators. Photograph the product label and both connections.
2. Confirm the application. Identify vehicle make, model, model year, engine family, emission level and market. A truck badge alone is not enough because aftertreatment layouts can change during a production run.
3. Compare the physical interface. Check body length and diameter, inlet/outlet diameters, clocking, sensor and pressure-port locations, bracket position, flow direction, gasket profile and clamp type.
4. Validate the complete service package. Treat clamps and gaskets as controlled sealing components. Confirm their material, profile, diameter and quantity instead of automatically reusing parts removed from a heat-cycled joint.
5. Document the decision. Keep the matched identifiers and measurements on the quotation or work order. That record improves traceability and makes a later technical review far faster.

This workflow is intentionally conservative. It reduces the three most common sources of avoidable returns: mixed-market catalog data, superseded numbers without context and assemblies that share a filter body but not the same ports or connections. When information conflicts, stop and request the VIN/serial number, engine data plate and photographs. A short verification pause costs less than shipping a bulky DPF twice.

Installation and quality-control checkpoints

Before assembly, inspect the mating flanges under good light. Remove loose residue without cutting or reshaping the sealing surfaces. Dry-fit the parts to confirm that the joint closes concentrically and that brackets are not forcing the filter sideways. Position the gasket correctly, seat the clamp evenly and follow the vehicle or component maker’s current torque procedure. Do not use clamp tension to pull a misaligned exhaust into place. After the first thermal cycle, inspect for soot tracks, unusual noise, contact with surrounding components and signs that the clamp has shifted.

For purchasing teams, quality control should begin before shipment. Request clear part markings, dimensional confirmation, packaging that protects ports and sealing faces, and a cross-reference record tied to the customer inquiry. For maintenance teams, keep removed parts available until the new assembly passes inspection. The old label, port arrangement and clamp footprint are valuable evidence if an application question appears.

Questions to send with an RFQ

• What is the complete OE number and are any prefixes or suffixes visible?
• Which vehicle, engine and model year is involved, and in which market does it operate?
• What are the canister and connection diameters, overall length and port locations?
• Are new clamps, gaskets, ropes or wire-mesh seals required as part of the job?
• Can the supplier confirm the match in writing and provide installation-relevant notes?

Frequently asked questions

Watch production cut-ins

Labels such as ‘to 2018,’ ‘2018 onward’ or ‘2022 onward’ are meaningful engineering boundaries. Ask for the build date rather than relying only on registration year. A vehicle registered later may have been built under the earlier configuration.

Include the sealing package

European kit data shows that one service event may require V-clamps, flat clamps, graphite or metallic gaskets, rope, knitwire or wire-mesh seals. Quote the assembly and service kit as separate, clearly identified line items so the workshop knows exactly what will arrive.

Does Euro VI identify one universal DPF?

No. Euro VI defines an emissions framework, not a single physical filter design.

Can truck and bus applications share a DPF?

Some catalog rows may relate, but body layout and connections must be checked for the exact application.

What information should a European inquiry include?

Vehicle maker/model, build date, engine, full OE number, emissions generation and photos/measurements of both connections.
