Renault Koleos Diesel Particulate Filter DPF

The DPF on Renault Koleos diesel engines captures the fine soot particles from exhaust gases to comply with Euro 4 anti-pollution standards. It is fitted on engines such as the 2.0 dCi (M9R, 150-173 hp, from 2008) and 1.6 dCi (R9M 409, 130 hp) models, mounted underneath the vehicle. The filter weighs approximately 6 kg and measures around 1005 mm in length.

The DPF treats diesel exhaust gas by trapping soot particles. It regenerates automatically either passively during high-temperature dynamic driving or actively by injecting fuel to heat the filter. A dashboard warning light indicates clogging. To clear it, maintain engine speed above 2000 rpm for 10-20 minutes; you may notice increased engine speed and fan operation. White smoke during regeneration is normal and harmless.

Urban driving often causes frequent clogging due to low temperatures preventing soot combustion. The DPF warning light signals the need for cleaning; if the message persists, repeat the process or consult a specialist. A caution warning light means immediate stop is required. Other common causes include faulty pressure pipes due to heat damage and clogged EGR valves. After a complete fuel run-out, priming is necessary before restarting the engine.

Preventive care includes long-distance trips of at least 20 minutes every 200 km, driving at a steady speed above 2000 rpm to enable regeneration. In city conditions, drive 30 minutes on the highway with speeds over 3000 rpm. Additives like DPF cleaners in spray or liquid form can be used to lower combustion temperature and clean associated parts like the turbo and injectors. Always check pressure pipes before deciding on replacement.

Original equipment (OE) references include 200106412R and 20010JY03A for the M9R-830 Euro 4 engine. New homologated DPFs certified with E-mark are available, compatible with Koleos and some Qashqai models 2.0 dCi (150/173 hp) from 2007 to 2014+, often inclusive of fitting kits and warranty. The filters are positioned under the rear seat area. For removal or replacement procedures, available YouTube tutorials offer detailed guidance.

To maximize DPF efficiency and reduce clogging, regular longer trips at a steady speed should be done. Avoid excessive idling or low-speed city driving that does not allow the engine and filter to reach the temperatures necessary for soot combustion. Monitor the dashboard for any DPF warning messages and act promptly. Regular maintenance and using recommended fuel additives can help improve the vehicle’s emission performance and prolong DPF life.

You may observe a dashboard warning light specifically for the DPF indicating clogging. Symptoms include reduced engine acceleration, increased fuel consumption, and unusual exhaust smoke (often white during regeneration). Persistent warning lights require repeated regeneration cycles or professional cleaning. Faulty pressure sensors or damaged pipes can also give false clogging signals and should be checked.
