Renault Fluence Diesel Particulate Filter DPF (2009-2020)

The Diesel Particulate Filter (DPF) in the Renault Fluence 1.5 dCi is a crucial component of the exhaust system designed to trap and burn fine particulate matter (soot) emitted by the diesel engine. It helps the vehicle comply with Euro 4 and Euro 5 emission standards by filtering particulates from the engine's exhaust gases.

The DPF for Renault Fluence 1.5 dCi (models L3_ or L38 with K9K engines) typically features:

• Materials: Cordierite or silicon carbide
• Length: Approx. 1090 mm, Weight: 10.9 to 11.8 kg
• Pipe diameter: 50 mm (may vary)
• Position: Front or centre/front exhaust assembly
• Includes a diesel oxidation catalytic converter and fitting kit
• Compatible with OBD-equipped vehicles

OE Renault references include 200101350R and others related to models 2008-2016.

The DPF functions by trapping fine particulates from the exhaust. To maintain efficiency, the filter needs regular regeneration which can be passive or active:

• Passive/Active regeneration involves driving at 60-80 km/h for approximately 25-30 minutes to reach the temperature necessary to burn off accumulated soot and cinders (max 60g)
• Diagnostic tools like VCDS can force regeneration if needed
• Professional cleaning services are available to remove deposits and extend the filter's life

Recommended replacement intervals are generally every 120,000 km, ideally between 140,000 and 180,000 km.

If the DPF is clogged or malfunctioning, you may notice:

• Increased diesel fuel consumption
• Loss of engine power or performance
• Illumination of the 'Check Engine' warning light

If these symptoms occur, it is advisable to have the DPF checked and diagnosed properly.

The DPF should be replaced if it becomes irreversibly clogged, typically between 140,000 and 180,000 km, or if regeneration attempts fail.

• Replacement kits include a mounting kit and pressure pipe
• Installation instructions and practical tutorials are available to guide fitting
• OEM-equivalent parts ensure compatibility and compliance with vehicle specifications

Consult a qualified mechanic if unsure about the replacement process or part compatibility.

DPFs are compatible with various Renault Fluence 1.5 dCi versions, including:

• Fluence L3_, L30, L30S, L38 with K9K engines (90 to 110 CV power outputs) from 2008/2009 to 2016
• Also compatible with related engine codes K9K 834, 836, 837, and 846 covering Euro 4 and Euro 5 standards
• Some cross-compatible parts with Renault Mégane and Scenic models

Always verify vehicle-specific references to ensure proper fitment.

The DPF is generally positioned at the front or centre/front section of the exhaust assembly. It is integrated with the diesel oxidation catalytic converter and connected through various flexible or pressure pipes.

• Exact location can vary depending on the vehicle model and year
• It is designed to intercept exhaust gases early to maximize particulate filtration and regeneration efficiency

Refer to vehicle manuals or technical guides for detailed instructions on locating and servicing the DPF.

To check for a clogged DPF, consider the following:

• Monitor fuel consumption and engine power – noticeable increases or decreases can indicate clogging
• Check for warning lights such as "Check Engine" on your dashboard
• Use diagnostic tools compatible with Renault vehicles to read error codes and pressure sensor data
• Forcing a regeneration cycle with appropriate software tools (e.g., VCDS) can help diagnose the filter's condition

Regular maintenance and suitable driving conditions (regular driving at 60-80 km/h for at least 25-30 minutes) help maintain the DPF's performance.

If in doubt, consult a Renault specialist or certified mechanic for accurate diagnosis and advice.
