Nissan Juke Diesel Particulate Filter DPF (2010-2019)

The Diesel Particulate Filter (DPF) on a Nissan Juke diesel is a crucial emissions system component that filters exhaust gases to remove fine carbon particles created during combustion. It helps reduce harmful emissions released into the environment and ensures compliance with emission regulations.

The DPF collects carbon particles from exhaust gases. Under normal driving conditions, these particles are periodically burned off through automatic regeneration, which cleans the filter. This process, called passive regeneration, keeps the DPF fully operational and effective at filtering pollutants.

DPF saturation or blockage can occur, especially with frequent short trips or urban driving at low engine speed, preventing proper regeneration. Symptoms include:

• Warning message: "Maintenance filter particulate. See maintenance guide"
• Orange or red fault light on dashboard
• Reduced engine power and limited RPM
• Engine power loss and potential engine shutdown

On Nissan Juke models with Renault K9K engines, turbo hose leaks are a frequent cause of DPF faults. The turbo hose must be replaced before the DPF to avoid repeated DPF damage and costly repairs.

There are two main methods to regenerate the DPF:

• Passive regeneration: Drive at a speed above 50 km/h (30 MPH) with moderate acceleration until the warning message disappears. This process safely burns off accumulated particles.
• Forced regeneration and hydrogen decarbonization: A technical cleaning technique injecting hydrogen into the air intake to promote DPF regeneration. Benefits include reduced fuel consumption, lower emissions, restored engine performance, and prolonged engine life.

Forced regeneration usually involves heating the DPF up to 420-550°C, depending on engine type, then cooling it to stabilize system performance.

For Nissan Juke with Renault K9K diesel engine:

• Engine: 1.5 dCi, 110 HP, code K9K410
• Emission standard: Euro 5
• DPF Position: Under the seat
• DPF Weight: 11.5 kg
• DPF Length: 1210 mm

Various OEM and equivalent part references are available for replacement.

The price for a Nissan Juke DPF typically ranges widely from around €14.49 to €1405.50, depending on the quality and origin of the part (OEM or aftermarket).

For best quality and compliance with manufacturer standards, choosing certified original parts like those offered by Krosfou is recommended.

Recommended maintenance practices include:

• Regular drives at speeds above 50 km/h to allow passive regeneration
• Avoid repeated short journeys and low engine speeds
• Maintain stable engine RPM
• Periodic hydrogen decarbonization treatments
• Check and replace the turbo hose and air intake system if faulty before DPF repair or replacement

Following these rules helps ensure the DPF functions correctly and reduces costly breakdowns.

Additional resources include:

• The official Nissan Juke user manual, section on DPF (e.g., 2024 version)
• Technical guides and videos on forced regeneration and decarbonization methods
• Certified DPF replacement parts with full technical data from trusted manufacturers like Krosfou
• Technical support and installation manuals available from specialist suppliers and professional garages

Always ensure maintenance and replacement comply with safety and legal requirements. For professional support, contact authorized garages and certified parts providers.
