Renault Kangoo Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) on Renault Kangoo diesel models, such as the 1.5 dCi, is a ceramic filter made of silicon carbide that traps fine soot particles emitted by the diesel engine. It reduces harmful particulate emissions by capturing up to 99% of these particles before they exit the exhaust system, helping to improve air quality and reduce respiratory risks.

The Renault Kangoo uses two types of DPF regeneration to clean trapped soot particles:

• Active Regeneration: The car's ECU raises exhaust gas temperature above 500-600°C by post-injecting fuel, oxidizing soot to CO2. This is automatically triggered every 300-800 km and lasts about 15 minutes, causing a slight fuel consumption increase of 2-5%.
• Passive Regeneration: During steady high-speed driving on highways (e.g., 130 km/h), exhaust heat naturally exceeds 600°C, burning off soot without requiring fuel injection.

Modern Renault Kangoo DPFs often include a platinum coating to lower the oxidation temperature and remove the need for cerium additives used in older versions.

DPFs on Renault Kangoo vehicles—especially the Kangoo II 1.5 dCi range—can clog rapidly during short city trips or low-speed driving that do not allow passive regeneration. Common symptoms include:

• Black smoke from the exhaust
• Loss of engine power and acceleration
• DPF warning light illuminated on the dashboard
• Increased fuel consumption

These issues occur due to soot and residue accumulation blocking the filter’s porous walls, impacting exhaust flow and engine performance.

Maintenance options for the Kangoo's DPF include:

• Decarbonisation Treatments: Chemical or mechanical cleaning without dismantling, suitable for models like the 1.5 dCi 82 hp.
• Professional Cleaning: Garage service involving flushing and high-pressure rinsing, often with promotional discounts available.
• DPF Replacement: New original parts for Kangoo II 1.5 dCi vehicles with warranty, with prices starting around £8.99.
• Standard Exchange: Exchanging an old DPF for a refurbished equivalent (note: no mention of reconditioned parts offered here).
• DIY Regeneration: Various video tutorials show how to perform forced regeneration without removing the DPF.

Regular motorway driving is recommended to facilitate natural regeneration and prolong DPF life.

The Renault Kangoo’s engine control unit (ECU) uses differential pressure sensors located upstream and downstream of the DPF to detect particle accumulation by measuring exhaust gas pressure differences. Temperature sensors also monitor exhaust heat to trigger regeneration. These sensors ensure timely detection of clogging and proper DPF function.

If the DPF warning light is illuminated, this usually indicates the filter is becoming clogged. Recommended steps include:

• Drive the vehicle on the motorway or fast road for at least 15-30 minutes to allow active regeneration and increase exhaust temperature.
• Follow any instructions from the vehicle’s onboard computer or manual regarding forced regeneration procedures.
• If the warning persists, consult a qualified mechanic or garage for a diagnostic check, pressure flow testing, and possible professional cleaning or replacement.

Ignoring the warning can lead to greater power loss, increased fuel consumption, and possible engine damage over time.

Original DPFs for Renault Kangoo models are available from specialized automotive suppliers focusing on high-quality, TÜV-certified parts made in Europe. Such DPFs are manufactured in stainless steel with advanced ceramic monoliths, ensuring durability and performance equivalent or superior to original equipment. Ordering online offers options for express shipping across Europe with real-time delivery tracking.

• Prices vary depending on model and stock availability.
• Express delivery options are possible, with shipping typically within 24-48 hours for in-stock items.
• Professional discounts and free returns may be available.

It is important to choose a compatible DPF based on vehicle specification (engine type, power, Euro standard) to ensure correct fit and function.

To maintain your diesel particulate filter and prevent premature clogging on your Kangoo, consider the following tips:

• Avoid predominantly short, low-speed urban trips which do not allow the exhaust to reach regeneration temperatures.
• Regularly drive at sustained speeds on highways or open roads to enable passive regeneration.
• Keep up with scheduled maintenance and use quality diesel fuel to limit contaminant buildup.
• Pay attention to dashboard warning lights and perform timely diagnostics.
• Consider professional DPF cleaning treatments when advised.

Following these practices improves exhaust flow, maintains engine power, reduces warning codes, and enhances fuel efficiency.
