Nissan Pulsar Diesel Particulate Filter DPF (2014-2018)

The Diesel Particulate Filter (DPF) on the Nissan Pulsar, especially models with the 1.5 dCi 110 HP engine (chassis C13), is a crucial exhaust system component that captures and removes harmful fine particles produced by incomplete fuel combustion. It helps reduce cancer-causing emissions and ensures compliance with strict European emission standards.

The DPF is placed after the turbocharger in the exhaust stream. It contains a ceramic monolith with a porous structure that traps fine particles (soot). Over time, soot builds up inside and creates back-pressure. Sensors monitor pressure and temperature to gauge this.

The filter undergoes regeneration to clean this soot, which happens in three ways:

• Passive regeneration: Occurs during long drives with high exhaust temperatures, burning off soot naturally with the help of the catalytic converter.
• Active regeneration: When conditions aren’t optimal, the engine management system injects additional fuel to increase exhaust temperature and burn off soot.
• Forced regeneration: Performed via diagnostic tools if automatic regeneration fails.

Short trips can clog the DPF faster, reducing engine power and raising fuel consumption, so occasional manual or long-drive regenerations are recommended.

The DPF is fitted mainly on the Nissan Pulsar 1.5 dCi 110 HP (chassis code C13), compliant with European emission regulations tested under ECE-ONU regulation 103 revisions. It is a standard component ensuring the vehicle meets Euro 5/6 standards.

The DPF is located in the exhaust system downstream of the turbocharger, integrated often with a catalytic converter, to effectively filter the exhaust gases before they exit the tailpipe.

A clogged DPF can cause:

• Reduced engine power and sluggish acceleration
• Increased fuel consumption due to back-pressure
• Illumination of the DPF warning light on the dashboard
• More frequent regeneration cycles and possible engine delivery issues

If you experience these symptoms, checking the vehicle’s fault codes with an OBD tool (e.g., code P2459) is recommended to confirm DPF clogging.

Yes, replacement is possible with the right tools and instructions. Detailed illustrated manuals and step-by-step video tutorials specifically for the Nissan Pulsar 1.5 dCi are available online. When replacing, be sure to address related components like sensors and gaskets as per manufacturer guidelines.

• Follow manufacturer service instructions carefully for removal and installation.
• Use OEM quality DPF replacements compliant with European regulations.
• Clear any vehicle error logs after replacement using OBD diagnostics to reset the system.

Incorrect installation or neglecting regeneration requirements can reduce DPF lifespan or void warranties.

Practical tips for DPF maintenance include:

• Drive regularly at elevated engine speeds (>2000 RPM) to promote passive regeneration.
• Monitor warning lights and scan for fault codes using an OBD tool.
• Ensure timely servicing of fuel injectors and engine oil to minimize soot production.
• Avoid excessive short trips that do not allow the engine to reach optimal temperature.

Regular maintenance helps keep fuel delivery and exhaust heating efficient for the DPF’s active regeneration cycles.

High-quality, original replacement DPFs for the Nissan Pulsar 1.5 dCi (C13) are available through reputable suppliers specializing in European-compliant automotive parts. These DPFs are manufactured with advanced stainless steel and ceramic honeycomb technology, certified to meet or exceed original equipment standards.

• Ensure the DPF is homologated under ECE-ONU 103 regulation to avoid issues with vehicle inspections and road compliance.
• Choose products with guaranteed compatibility and a warranty of typically 3 years or 100,000 km usage limit.
• Reliable suppliers also offer technical support, installation guides, and fast European delivery options.

Buying quality DPFs ensures proper fit, durability, and emission performance, maintaining your Nissan Pulsar’s engine power and efficiency.
