Nissan Note Diesel Particulate Filter DPF

The DPF in a Nissan Note Diesel is a device that captures soot and harmful fine particles from the exhaust gases using a porous ceramic or metallic substrate located after the turbocharger. It operates by filtering soot and regenerating by burning the trapped particles at temperatures above 500°C through passive or active cycles, monitored by sensors and the ECU.

The Nissan Note models equipped with DPF include Note I (E11, NE11) with 1.5 dCi 90 hp engines produced between 2010 and 2013, complying with Euro 5 standards. The DPF material is typically cordierite with a maximum ash load of 60 g before regeneration or replacement. It is recommended to replace the DPF between 140,000 and 180,000 km to avoid failures.

Common DPF problems include clogging/blockage caused by short trips, improper oil, and failed regeneration, which manifest as performance loss, warning lights, limp mode, and ECU error codes.

• Oil contamination due to failed regeneration can lead to elevated oil levels and engine issues.
• Sensor faults from damaged pipes or sensors can cause false DPF alerts, increased fuel consumption, and power loss.

Other signs include increased fuel consumption and persistent "Check Engine" lights.

Maintain your DPF by driving for over 30 minutes at steady speeds (65-80 km/h) to allow passive regeneration. Avoid frequent stopping and restarting. Use low-ash engine oils to prevent catalyst poisoning. Regularly check differential pressure sensors, EGR valves, and pipes. Professional diagnostics and resetting the ECU or ash counter are recommended. Chemical additives and professional cleaning services can also help regenerate or clean the DPF effectively.

Replacement is needed when warning lights persist after regeneration, irreversible clogging occurs, or backpressure causes limp mode. It is essential to use original, high-quality DPFs compatible with your vehicle’s Euro norm and engine code. Installation should be done professionally with ECU reset and sensor checks. Replacing upstream and downstream catalytic converters, if present, is recommended during DPF replacement.

Yes, you can attempt home cleaning using recommended chemical additives tested for effectiveness. However, it requires proper procedures such as heating the DPF above 500°C during driving. Professional cleaning services or diagnostic tools (like VCDS) offer more reliable regeneration. Avoid illegal DPF removal or disabling, which violates emission regulations and can cause legal and warranty issues.

• Use only additives approved for your vehicle type
• Follow manufacturer and legal safety regulations
• Professional advice and services are recommended for best results

Regular maintenance and proper driving habits remain the most effective ways to prolong DPF life and avoid costly replacements.

For expert diagnostics and advice, consult Nissan garages or professional automotive diagnostic centers. Online tutorials and manuals provide step-by-step guides for DPF replacement and maintenance. Helpful video resources explain DPF operation and safe cleaning methods. For purchasing original parts and technical support, consider trusted manufacturers offering certified products compliant with all safety and environmental rules.

• Contact technical support teams for vehicle-specific compatibility checks.
• Use official diagnostic tools to reset error codes and sensor calibration.
• Always follow legal conditions and manufacturer recommendations for repairs.

Never ignore safety rules and conditions related to your Nissan Note DPF system to ensure optimal performance and compliance with environmental standards.
