Renault Modus Diesel Particulate Filter DPF

The DPF on Renault Modus diesel models, mainly the 1.5 dCi engines (such as JP1D, FP0F, JP0F, or K9K 766/768), is a mandatory anti-pollution device integrated into the exhaust line since 2011. It is located between the catalytic converter and the rear silencer and captures harmful fine soot particles from diesel combustion through a honeycomb structure made of cordierite or silicon carbide. These soot particles are trapped in porous walls and then burned off during a high-temperature regeneration phase, reducing harmful emissions.

The DPF without additive on the Modus 1.5 dCi captures 95-99% of particulate matter. Its operation includes two main phases:

• Filtration: The filter traps soot particles effectively during normal operation.
• Regeneration: This can be passive, occurring automatically when driving at high engine speeds (above 2500 rpm), or forced via diagnostic tools. During forced regeneration, the engine revs rise to 2500-3000 rpm for 15-20 minutes while monitoring DPF temperature and pressure.

The DPF is positioned just after the engine outlet and before the silencer, with a typical capacity around 0.4 liters for some models.

DPF clogging on Renault Modus is often caused by frequent short urban trips, poor fuel quality, or faulty EGR valves leading to soot and ash accumulation. Common warning signs include:

• DPF warning light on the dashboard
• Loss of engine power
• Black smoke from the exhaust
• Multi-function screen alerts

If ignored, clogged DPF can trigger engine faults or damage.

To prevent DPF clogging, consider these tips:

• Use premium fuel with additives
• Avoid frequent short trips; regularly drive 20-30 minutes at engine speeds above 2500 rpm
• Check the EGR valve and engine oil level to prevent excessive oil causing damage

Forced/manual regeneration steps with a diagnostic tool on a warm engine (fuel tank above 1/4) include starting regeneration, monitoring with headlights and maximum fan speed on, and resetting adaptation codes after completion. Chemical additives added to the fuel tank can also help dissolve soot build-up.

Note: Deleting or reprogramming the DPF is not recommended except as a last resort for very high mileage vehicles.

DPF replacement is rare but necessary if regeneration is impossible due to heavy ash accumulation. Replacement costs for a new DPF range typically between €500 and €1500 including installation.

Example parts references include:

• Modus/Grand Modus 1.5 dCi JP1D – Reference: DPF-G3090
• Grand Modus 1.5 dCi 86 CV K9K 766 – Reference: 88090 (3RG), capacity 0.4 L

Always verify vehicle compatibility with VIN or diagnostic information before ordering.

Signs your DPF may be clogged include persistent warning lights, high DPF pressure readings, loss of engine performance, and black smoke emissions. A faulty DPF pressure sensor can also cause elevated pressure readings or error codes.

• Check for fault codes such as P242F via OBD2 diagnostics
• Monitor DPF pressure sensor values in your engine control unit log
• Look for symptoms like engine hesitation, rough idling, or increased fuel consumption

Early diagnosis helps avoid serious engine or exhaust system damage.

DPF replacement requires mechanical skills and proper tools due to the location on the exhaust line and sensor connections. It is recommended to have replacement done by a professional garage to ensure correct installation, sensor calibration, and to maintain warranty conditions.

• Replacement involves removing the exhaust pipe section housing the DPF
• New gaskets, sensors, and injectors should be replaced as per manufacturer instructions
• Post-installation requires diagnostic tool usage to reset DPF system adaptations and perform test regenerations

Improper installation or neglecting sensor replacements can cause system faults or damage.
