Nissan Navara Diesel Particulate Filter DPF D40 (2004-2021)

The Diesel Particulate Filter (DPF) for Nissan Navara D40 is an essential emission control device designed specifically for diesel engines, mainly fitted on 2.5 dCi YD25DDTi (171-174 HP) and 3.0 dCi 4WD (231 HP) models. It captures and removes particulate matter (soot) from the exhaust gases to reduce harmful emissions and ensure compliance with Euro 5 and Euro 6 standards.

The DPF is compatible with the following Nissan Navara D40 diesel engines and models:

• 2.5 dCi YD25DDTi diesel engine with 171 to 174 HP, 4WD versions, Euro 5 standard, for models produced until 01/2010 or between 2010-2015 (2nd generation DPF).
• 3.0 dCi 4WD diesel engine with 231 HP, Euro 6 standard, featuring a silicon carbide based filter of approximately 530 mm length and 10.7 kg in weight.
• Applicable to Navara D40 models from October 2006 onwards.

Main technical specifications for Nissan Navara D40 DPFs include:

• Material: Stainless steel shell; some models use silicon carbide monoliths.
• Emission standards: Euro 5 (E-Mark) for 2.5 dCi and Euro 6 for 3.0 dCi versions.
• Weight: Approximately 10.7 kg for the 3.0 dCi DPF.
• Dimensions: 530 mm length for the 3.0 dCi DPF.
• OEM References: B08025X00A, B08025X30A, among others.
• Additives: Aerosol treatments available for maintenance (e.g., 400 ml spray recommended at minimum 5°C).

These features ensure effective filtration and long-lasting durability compliant with environmental regulations.

Possible signs of DPF malfunction or clogging include :

• DPF warning light appearing on the dashboard.
• Reduced engine power or turbo performance.
• Increased exhaust pressure and reduced fuel efficiency.
• Excessive smoke or smell from the exhaust pipe.
• Frequent regeneration cycles or failure to complete regeneration.
• Vehicle entering limp mode or showing fault codes related to the DPF system.

If you notice these signs, it is advisable to have the DPF system inspected and serviced promptly to avoid damage or costly replacements.

Cleaning the DPF is often possible and recommended as a first step if the filter is clogged but still structurally sound. Techniques include manual cleaning with specific additives or professional cleaning machines that remove accumulated soot and ash.

• Use recommended aerosol additives to assist regeneration and reduce soot build-up.
• Regular regeneration by driving at suitable speed and conditions helps maintain the filter's function.
• If the DPF is severely damaged or the filter substrate is cracked, replacement is necessary.

Consult certified specialists or your vehicle service manual for the best approach to maintain or service your DPF.

DPF regeneration is a process that burns off accumulated soot particles inside the filter to restore its filtering capacity and avoid clogging.

This can happen in three ways :

• Passive regeneration: Occurs automatically during normal driving conditions at high exhaust temperatures.
• Active regeneration: Engine management injects additional fuel to raise exhaust temperature and burn off soot when sensors detect the filter filling up.
• Forced regeneration: Performed by mechanics using diagnostic tools when normal regenerations fail.

Regular regeneration prolongs DPF life, keeps engine performance optimal, and prevents warning lights or costly repairs.

You can order high-quality new original DPFs compliant with European regulations directly from trusted manufacturers like Krosfou, offering a 3-year warranty and TÜV certified products.

• Specify your vehicle's VIN and engine details to ensure exact compatibility (e.g., 2.5 dCi YD25DDTi or 3.0 dCi 4WD engines).
• Choose products manufactured with high-grade stainless steel (Inox 409) and premium monoliths for durability.
• Utilize factory direct supply options for best price and warranty coverage.

Always check the product reference numbers and Euro standard compliance before purchasing.

Removing the DPF is not recommended as it will cause warning lights to appear on the dashboard, trigger fault codes, and is illegal under European emissions laws.

• DPF removal compromises environmental compliance by releasing harmful particulate emissions.
• It can lead to vehicle inspection failures and legal penalties.
• Removing the DPF may affect fuel pressure, exhaust back pressure, and turbocharger function, potentially causing engine damage over time.

For these reasons, always maintain or replace the DPF rather than removing it.

Protect your vehicle, preserve performance, and respect emission regulations by opting for genuine, certified DPF units and professional services.
