Diesel particulate filter (DPF)

So you've tried the cleaning methods, run regenerations on the motorway, and maybe even paid for a professional flush, but the DPF warning light keeps coming back? Once a diesel particulate filter is cracked, melted, or so heavily ash-laden that regen cycles can't clear it, replacement is the only fix left. The DPF sits in the exhaust line between the engine and the rear silencer, trapping soot from the diesel combustion process so it doesn't reach the atmosphere. A failed DPF puts the engine into limp mode, can trigger an MOT failure on emissions, and over time damages the turbo and EGR system by raising back-pressure, so a sound replacement matters. Hunting one down online is the chore, with listings spread across breakers, exhaust specialists, and parts marketplaces with very different conditions.Parthunt24 brings used DPF listings together from marketplaces like eBay, Ovoko, RicambiPro, Opisto, Proxyparts, Ecooparts, Autoparts-24, Totalparts. Compare 514 options on price, condition, and fitment, then head to the marketplace once you've found the right DPF.

A Diesel Particulate Filter (DPF) is an exhaust system component, mandatory on modern diesel cars (Euro 5/6), that captures and stores soot to reduce emissions, trapping up to 100% of particles. It requires "regeneration," a process that burns off accumulated soot at high temperatures, usually while driving at higher speeds, to prevent clogging. Compatibility starts with the OEM number, followed by the emissions standard (Euro 5 vs Euro 6), sensor connections, and pipe diameters. A DPF pulled from a slightly different model year may carry different sensor ports or fail to talk to the ECU's regen strategy. Run your OEM code or car details through the Parthunt24 search bar, and the filters along the side (Category, Manufacturer, Series, Model, Modification, Price) cut the list down to fitting filters. Clicking any result takes you across to the marketplace it's listed on, where the seller handles the description and the purchase.

• Vehicle & engine compatibility: Match make, model, year, engine code, and OEM part number.
• Emissions standard: Verify Euro emissions compatibility (Euro 4, Euro 5, Euro 6, etc.).
• DPF type: Passive vs active regeneration system.
• Sensor compatibility: Check the pressure sensor and temperature sensor connections.
• Mounting configuration: Ensure flange positions and pipe routing match.
• Exhaust system compatibility: Confirm fit with catalytic converter and exhaust layout.
• Regeneration system support: Verify compatibility with the vehicle ECU regeneration strategy.
• Dimensions & pipe diameter: Match physical size and inlet/outlet diameters.
• Material & core quality: Cordierite vs silicon carbide construction.
• AdBlue / SCR compatibility: Some modern diesel systems integrate DPF with SCR systems.
• OEM vs aftermarket: Ensure certified emissions compliance where required.
• Condition: Check ash accumulation, cracks, clogging, and cleaning history.

The listing itself has to give you enough detail to feel confident in the buy. A used DPF can look fine from outside the casing, while the ceramic core is cracked, melted, or saturated with ash beyond cleaning, so internal-condition notes matter more than they do on most parts.

• Photos: Clear shots of the casing, inlet and outlet flanges, sensor ports, and core.
• Seller reputation: Buyer feedback, sales history, and review quality.
• Compatibility: OEM number and emissions standard checked against your engine.
• Included components: Bare DPF, with sensors, gaskets, or clamps?
• Condition: Ash level, soot loading, cracks, and signs of internal melting.
• Testing: Notes confirming the core was inspected or pressure-tested.
• Warranty and returns: A clear path if the DPF arrives cracked or unusable.
• Shipping: Padded packaging to protect sensor ports and flange faces.

DPF filter price varies a lot with the vehicle, the emissions standard, and whether you're buying an as-removed unit or a cleaned one. A used DPF from a common Euro 5 diesel opens at €100-€250, mid-range cleaned and tested filters sit at €300-€600, and OEM DPF/SCR combined units for premium Euro 6 diesels can push past €1,000.Across Parthunt24 listings, a DPF for sale starts from as low as 14.03. Factors that move the DPF filter price up or down:

• Emissions standard: Euro 5 sits below Euro 6, which sits below combined DPF/SCR units.
• Condition: As-removed sits below cleaned, which sits below newly remanufactured.
• Brand: OEM sits at the top of the range; quality aftermarket sits below.
• Vehicle rarity: Common diesels are cheaper; specialist applications cost more.
• Inclusions: Sensors, gaskets, and clamps bundled bump the DPF filter price.

Browsing DPF filter prices on Parthunt24 makes it easy to skip past tired pulls and find a cleaned, tested unit.

A blocked DPF rarely stays an isolated fault. The raised back-pressure works its way through the rest of the exhaust and intake systems, dragging neighbouring components down with it. Driving long-term with a clogged DPF can take out the turbo, EGR valve, and injectors in sequence, turning a manageable repair into a five-figure bill, so dealing with it quickly saves serious money. Browse these on Parthunt24 alongside the DPF:

• Turbocharger: Excess back-pressure stresses the turbo and can cause early failure.
• Engine: Severe clogging causes power loss, oil dilution, and long-term internal damage.
• EGR valve: Carbon and soot build-up often coincides with DPF blockage.
• Exhaust pipe: Sections downstream of a failed DPF can suffer heat damage from incomplete regen cycles.
• Pressure sensor: Often, the part actually triggering DPF warnings on a healthy filter.
• Temperature sensor: Faulty readings prevent regen cycles from running at all.
• Fuel injectors: Oil dilution from incomplete regens shortens injector life.

Sourcing a used DPF online across breakers, exhaust specialists, and parts marketplaces takes serious time once Euro standard, sensor configuration, and core condition have to align. Parthunt24 gathers every compatible DPF online listing onto one filterable page, with condition, price, and donor mileage laid out together.Euro 5, Euro 6, and combined DPF/SCR units for most diesels on European roads all appear in the same results.
