Renault Kadjar Diesel Particulate Filter DPF (2015-2022)

The DPF is installed on diesel engine versions of the Renault Kadjar (for example 1.5 dCi, 1.6 dCi). It is not present on pure petrol versions like the 1.2 TCe or 1.6 TCe.

The DPF captures fine particulate matter from the exhaust gases. It operates in two main phases :

• Filtration : trapping soot particles from diesel combustion in the exhaust manifold.
• Regeneration : automatic combustion of accumulated particles at high temperature, even during urban driving, to keep the filter clean.

A warning light on your dashboard often indicates when the DPF needs cleaning or servicing.

Maintenance mainly consists of :

• Regular driving at sustained speeds to trigger natural regeneration of the DPF filter.
• Professional forced cleaning using gas injection to boost regeneration and remove soot deposits.
• Monitoring the DPF warning light to address clogging early and avoid premature replacement.

Periodic cleaning preserves exhaust system parts including the catalytic converter and engine sensors.

Replacement times depend on the engine version but generally range from about 3 to 5 hours of labour. Estimated times include :

• Approx. 4h 30min for 1.5 dCi diesel versions
• Approx. 4h 18min for 1.6 dCi 130cv engines
• Shorter time (~3h 11min) for some petrol variants, though these models usually lack a DPF

Costs (parts + labour) generally range from around €1,100 to €1,460 including VAT, depending on the engine version and whether the new filter includes an integrated catalytic converter. All new parts come with a 2-year manufacturer guarantee.

For diesel versions such as the 1.5 dCi, new DPF spare parts with or without catalytic converters are available with professional kits and a 2-year warranty. Specific DPFs for the 1.6 dCi 130cv 4x4 (Euro 6 R9M 414 engine) include refundable consignment fees.

Only purchase genuine new parts manufactured in stainless steel INOX 409 with approved ceramic monoliths to ensure efficient exhaust emission control and durability.

Yes. Illustrated manuals and step-by-step video tutorials exist to assist DIY enthusiasts or professionals in dismantling and replacing the DPF on Renault Kadjar models.

• These guides cover necessary tools, removal of exhaust parts including manifolds, and proper fitting of the new DPF and catalytic converter.
• Following these detailed instructions ensures correct installation and avoids damage to the engine or exhaust flex valve systems.

Consult your garage or trusted sources for resources respecting safety and technical standards.

Common causes for DPF clogging include frequent short trips, poor engine performance, or failure of related parts such as the oxygen sensor, flex valve, or catalytic converter.

• Symptoms include illuminated DPF warning light, reduced engine power, increased exhaust smoke, or unusual noise from the exhaust manifold.
• Diagnostic tools connected via OBD can identify faults in the DPF system and associated engine control sensors.

Early detection and maintenance help to avoid expensive replacements and protect the engine’s emission control components.

The DPF is part of a complex exhaust and emission system including :

• The catalytic converter (sometimes integrated with the DPF) which reduces harmful gases.
• The exhaust manifold which collects gases from the engine cylinders to the DPF.
• Flex pipes and valves that help manage exhaust flow and pressure for proper engine operation.

Maintaining the entire exhaust system in good condition ensures optimal performance of the DPF and engine emissions compliance.

If you notice any dysfunction or warning signs, have your vehicle inspected by a professional to prevent further damage.
