Nissan Primastar Diesel Particulate Filter DPF (2002-2016)

The Diesel Particulate Filter (DPF) on Nissan Primastar diesel vehicles is a key component of the exhaust system. It captures and removes fine soot particles from the exhaust gases to reduce pollution and comply with emissions standards like Euro 6 D-full.

The DPF traps carbon particles from diesel combustion. It uses periodic regeneration to burn off accumulated soot by raising exhaust gas temperature. This is detected and controlled via differential pressure sensors and temperature probes in the exhaust. Regeneration can be aided by fuel additives or performed passively through high heat.

Nissan Primastar diesel models with DPF include:

• Primastar dCi 150 (X83): 146 HP, from 2006/07 to 2011/11, standard diesel DPF
• Primastar 2.0 dCi (e.g., Bus variant): 120 HP, Euro 6 D-full, with DPF and AdBlue® injection
• Primastar Fourgon/Cabine Approfondie: 125-145 HP estimated, Euro 6 D-full, DPF + AdBlue® system

These vehicles incorporate advanced features like turbocharging, Start & Stop systems, and selective catalytic reduction through AdBlue®.

Common issues include blockage or clogging, characterized by loss of power, illuminated warning lights, and high exhaust back pressure measured by sensors. Causes often involve short trips limiting regeneration, faulty fuel additives, or use of unsuitable engine oils with high phosphorus content.

• Symptoms: reduced engine performance, warning light on dashboard
• Detection: monitored by ECU using differential pressure and temperature sensors
• Causes: short urban trips, failed additives, oil contamination

DPF maintenance includes regular automatic regeneration during driving, especially at highway speeds. For blockage risks in city driving, professional cleaning or use of fuel additive products is recommended. Additives help lower regeneration temperature to burn off soot effectively.

• Automatic regeneration by ECU during normal driving
• Use of fuel additives formulated for the Nissan Primastar 2.0 dCi (e.g., 1L bottles)
• Professional cleaning services for thorough soot and deposit removal

Regular maintenance extends DPF life and maintains engine performance.

DPF replacement is generally required every 80,000 to 140,000 km depending on vehicle use and maintenance. Long-term accumulation of cerium from additives and phosphorus from oils reduces filter efficiency, making replacement necessary.

Replacement must use high-quality, certified DPF units that match the Nissan Primastar engine specifications to ensure compliance and performance.

• Ideal replacement interval: 80,000 to 140,000 km
• Use OEM-quality or certified DPF compatible with Nissan Primastar engine codes
• Replacement recommended when cleaning or regeneration no longer restores performance

AdBlue® is a urea-based additive used in the Selective Catalytic Reduction (SCR) system. It complements the DPF by chemically reducing nitrogen oxides (NOx) emissions in the exhaust on Euro 6 D-full models. The Nissan Primastar 2.0 dCi engines feature an AdBlue® tank with about 24.7 liters capacity to support this function.

• Reduces harmful NOx emissions via SCR catalyst
• Must be regularly refilled from a dedicated onboard tank (approx. 24.7 L)
• Works in tandem with the DPF to meet strict Euro 6 emission standards
