Nissan Primastar Diesel Particulate Filter DPF (2002-2016)

The Diesel Particulate Filter (DPF) on the Nissan Primastar is an exhaust system component designed to capture soot and fine particulate emissions from diesel engines. It primarily applies to Euro 4 standard engines, especially the 2.5 dCi 145/150 HP models produced between 2003 and 2014. The DPF is made of a ceramic honeycomb structure that traps particles and periodically regenerates by burning off accumulated soot at temperatures above 600°C through post-injection fuel strategies.

The DPF system works by filtering soot particles from the exhaust gases. Key components include :

• Ceramic filter: A honeycomb structure that traps particulates.
• Pressure sensors: Two differential pressure sensors positioned before and after the DPF measure filter clogging by comparing pressure differences.
• Pressure hoses: Rubber hoses that connect sensors and can be prone to heat-related cracks or leaks.

When clogging is detected via sensor inconsistencies, the vehicle triggers a DPF warning and can activate limp mode to reduce engine output.

Common faults include :

• Persistent DPF warning light on the dashboard.
• Loss of engine power or reduced performance.
• Failed automatic or forced regeneration cycles.
• Fault codes related to DPF pressure sensor inconsistencies.

Diagnosis should involve checking the pressure sensors and hoses for leaks or damage before assuming the filter is blocked. A faulty EGR valve or other engine issues can also cause premature DPF clogging. Accurate fault diagnosis prevents unnecessary DPF replacements.

DIY cleaning is possible and can be cost-effective. Available methods include using special additive products (~£30-40) or performing sensor diagnostics with inexpensive tools (~£5-10). However, correct diagnosis is essential to ensure cleaning is appropriate. Professional cleaning services or replacement may be needed if the filter is severely clogged.

Regular maintenance to ensure components like EGR valves and pressure hoses are in good condition helps prolong DPF life and prevent blockages.

Replacement involves:

• Obtaining the correct OEM or approved DPF part designed for your model and engine (e.g., 2.5 dCi 145 hp Euro 4).
• Removing the exhaust components carefully to access the DPF and disconnecting pressure sensors.
• Installing the new DPF, ensuring precise re-fitting of bolts, sensors, and hoses.

Guides and video tutorials are available to support step-by-step replacement. Always verify the condition of related parts like EGR valves before installation to avoid repeated clogging.

New DPFs for Nissan Primastar 2.5 dCi 145 HP Euro 4 models typically cost around £170 to £200 including mounting kits. Total professional replacement prices including labour may start from £900 to over £1,000 depending on the garage.
