Peugeot 307 Diesel Particulate Filter DPF

A diesel particulate filter is a vital part of your car’s exhaust system. It traps harmful particles, or soot, before they exit the tailpipe. This keeps your Peugeot within emission limits, reduces environmental impact, and helps avoid MOT failures.

Your DPF works in tandem with the catalyst to break down pollutants. Over time, soot builds up—leading to possible blocking if not cleared. This can cause a risk to both fuel efficiency and engine components.

Here’s a quick price list based on common Peugeot engine codes and Euro standards:

Whether you’re buying just the filter or a full kit, we ensure fast shipping, excellent condition, and value that beats most garages.

Use your Peugeot’s engine code, fuel type, and production year to find the correct fit. Examples:

• 1731EP – fits 1.6 HDi (Euro 4)
• 1731S7 – fits 2.0 HDi 110 (Euro 3)
• 174007 – fits 2.0 HDi 135 (Euro 4)

All DPFs in our shop include accurate fitment details, and many fits Peugeot models directly with no modification.

Certain models, especially Peugeot 307 diesel, require additive fluid to aid DPF regeneration. These additives lower the exhaust gas combustion temperature, helping your particulate filter clean itself during driving.

A refill is typically needed every 60,000 to 80,000 km. Our store offers multiple pouch sizes to match your system—just add to your basket and choose your delivery option.

If your DPF is blocked, don’t panic—here’s how to deal with it:

• Use a specialist cleaning fluid such as Wynn’s to dissolve soot
• Drive on a motorway for 20–30 minutes to activate passive regeneration
• If these steps don’t work, it’s time for a professional service or replacement

A persistently clogged filter increases exhaust pressure and can damage your catalyst or EGR system. Our how-to guide in the content section breaks it down.

Watch out for:

• DPF or engine warning light
• Reduced air intake, power, or responsiveness
• Rising fuel use or smoke from the tailpipe
• Oil contamination or frequent regen cycles

These signs point to a filter fault. Don’t ignore it—it increases the risk of more serious problems like hose damage, sensor failure, or converter wear.

Here’s a simplified DIY process:

• Lift the vehicle with a jack or ramps
• Unplug the pressure sensor and temperature sensor
• Detach the DPF from its mounting brackets and exhaust pipe
• Install the new filter and secure all fittings

You’ll need a mounting kit, basic tools, and our DPF-specific tips to make it smooth. Our step-by-step guide has full visuals and torque settings.

Not always. If the DPF is only partially blocked, cleaning and regeneration might solve the issue. But if there's structural damage, failed mounting points, or high soot levels, a new filter is safer and longer-lasting.
