Renault Kangoo Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) fitted on Renault Kangoo Diesel engines, especially the 1.5 dCi version, is an antipollution device made of porous ceramic materials (silicon carbide). It is integrated into the exhaust pipe to trap harmful fine soot particles emitted by the diesel engine, thereby significantly reducing black smoke emissions and respiratory health risks.

The DPF operates in two main steps:

• Particle trapping: Soot particles composed of a carbon core and organic compounds are captured within the filter's pores. Renault’s technology uses a platinum coating instead of cerium additive to lower oxidation temperature.
• Automatic regeneration: Every 300 to 800 km depending on driving conditions (city, highway, load), the system initiates a 15-minute regeneration by delaying fuel injection to heat exhaust gases and oxidize trapped soot. On highways at 130 km/h, regeneration is spontaneous without post-injection, saving 2-5% fuel.

This system is mostly effective on long drives and is less suitable for short city trips which cause quicker clogging.

Common symptoms indicating DPF clogging include:

• DPF warning light or engine light illuminating on your dashboard.
• Reduced engine power caused by exhaust pressure build-up.
• Soot accumulation exceeding 40-50 grams, meaning the filter is considered blocked, and automatic regeneration becomes ineffective.

Monitoring the pressure differential sensor helps identify excess soot build-up inside the exhaust pipe.

Several solutions are available to maintain or restore your Kangoo’s DPF functionality:

• Forced regeneration: Activated through a diagnostic tool to burn accumulated soot during driving once soot volume exceeds 40-50 g.
• Chemical cleaning without removal: Injecting specific cleaning agents into the DPF followed by idling and progressive acceleration to dissolve and expel soot residues safely.
• Preventive additives: Fuel additives like C99 used regularly can help keep the injection clean and prevent DPF clogging, especially in regions like Guadeloupe.
• Replacement: Recommended if cleaning is ineffective or soot exceeds limits, using a new genuine DPF designed for the Renault Kangoo 1.5 dCi model (e.g., KW0F code).

Always use original quality parts matching your vehicle's code and follow professional installation guidance.

Yes, to preserve your DPF’s lifespan:

• Avoid short trips under 10 minutes and exclusive urban driving, which prevent the engine from reaching optimal temperature for regeneration.
• Prefer highway driving where higher speeds and temperatures naturally support the regeneration process.
• Regularly check your vehicle with a diagnostic tool to monitor the DPF status and sensor pressures.
• Use fuel additives as a preventive maintenance measure according to manufacturer recommendations.

Note that from 2018, petrol engines with direct injection (like 1.3 TCe) on Kangoo models also come fitted with particulate filters.

The DPF system includes differential pressure sensors placed before and after the filter in the exhaust pipe. These sensors measure the pressure difference to detect soot load volume.

If the sensor readings indicate higher-than-normal pressure, the engine control unit triggers warning lights on your dashboard (DPF or engine light) to alert you of possible clogging restricting diesel gas flow and reducing engine power.

• Regular sensor checks ensure accurate monitoring of the particle filter health.
• A faulty sensor can cause erroneous warnings or mask real problems, so sensor and wiring inspections are part of proper diagnostics.

The DPF is standard on most Renault Kangoo Diesel models such as the 1.5 dCi Blue dCi R7N engine, widely used across European markets. It is also fitted on newer petrol engines with direct injection since 2018.

• Fitment and sensor configuration may vary depending on model year, engine code, and regional emission standards (Euro 4, Euro 5, Euro 6).
• Always check compatibility with your vehicle’s VIN or original part code before ordering replacement parts.
• Krosfou offers original-quality DPFs compliant with current European regulations and certified by TÜV SÜD to ensure perfect fit and function.

Signs to check whether your Renault Kangoo's DPF is clogged include:

• Illumination of the DPF or engine warning light on your dashboard.
• Reduction of engine power and acceleration issues due to blocked exhaust flow.
• Diagnostic scan showing high differential pressure sensor readings or soot volume above 40-50 grams inside the filter.
• Unusual smoke or smell from the exhaust pipe during operation.

If you detect these symptoms, consider forced regeneration via a diagnostic tool, professional chemical cleaning, or ultimately replacement with an original DPF that fits your Renault Kangoo diesel engine to restore optimal engine and exhaust performance.
