Renault Kadjar Diesel Particulate Filter DPF (2015-2022)

The Diesel Particulate Filter (DPF) on Renault Kadjar diesel models, such as the 1.5 dCi 110 hp engines (K9K series) and Energy dCi 130, is an emission control device designed to trap soot particles from the exhaust gases. It ensures compliance with Euro 5 and Euro 6 emissions standards by capturing particulate matter that would otherwise be released into the atmosphere.

The DPF cleans itself through an automatic process called active regeneration. When the filter reaches saturation, a dashboard warning light appears, prompting the driver to maintain an engine speed of at least 2,000 rpm and a speed of 60-80 km/h for 10 to 30 minutes until the warning light turns off (typically after 10-20 minutes). The engine may increase idle speed and cooling system activity to aid the cleaning process. Passive regeneration can also occur if conditions are hot enough, otherwise the system actively raises the temperature to burn off soot.

If the vehicle is stopped prematurely or driven at low rpm, the regeneration fails, and the warning light will prompt the process to repeat.

Signs indicating a DPF issue may include :

• DPF warning light or Check Engine light illuminated on the dashboard.
• Loss of engine power or reduced vehicle performance.
• Increased diesel fuel consumption.
• Occasional white smoke, often linked to ongoing cleaning or fuel quality.
• Error codes related to differential pressure sensors before and after the DPF, indicating filter saturation.

Addressing these symptoms promptly helps avoid irreversible clogging.

DPF maintenance options include :

• Driving at highway speeds (60-80 km/h) for 25-30 minutes to encourage active regeneration.
• Using diagnostic tools like VCDS to initiate cleaning cycles.
• Applying chemical additives such as a 400 ml Valvoline aerosol to remove ash buildup.
• Professional cleaning services specifically for Renault Kadjar DPFs can extend filter life and improve emissions.

Regular maintenance helps prevent permanent clogging and reduces fuel consumption.

It is generally recommended to replace the diesel particulate filter every 125,000 to 175,000 km to avoid failures and irreversible clogging due to ash accumulation exceeding 60 grams. Replacement parts consist of high-quality original DPFs made with cordierite or silicon carbide monoliths, with an approximate weight of 6 to 7.4 kg.

Using original quality parts ensures performance and compliance with Euro 5/6 emissions standards.

DPFs are fitted on Renault Kadjar models HA_ and HL_ with 1.5 dCi 110 hp (HLA3 code), and Energy dCi 130 diesel engines produced from July 2015 to August 2018 and beyond for some variants. These vehicles feature OBD systems and integrated catalytic converters adhering to Euro 5 and Euro 6 regulations.

• DPF material: cordierite or silicon carbide.
• Weight: 6 to 7.4 kg.
• Length approx. 440-450 mm.
• Original part numbers include 208A07274R and 208A06183R.
• Parts come with assembly kits and documentation.

Ensure compatibility by checking engine codes and part references when replacing the filter.

To determine if the DPF is clogged :

• Monitor for DPF or Check Engine warning lights on the dashboard.
• Use an OBD diagnostic tool to check pressure differential sensor readings before and after the DPF.
• Observe for decreased engine performance and increased fuel consumption.
• If regeneration attempts fail repeatedly, clogging is likely.

If a clog is suspected, pursue professional diagnostics and cleaning or replacement as needed to maintain vehicle function and reduce emissions.

Original DPF replacements from trusted manufacturers like Krosfou are made in Europe with stainless steel INOX 409 shells and high-grade monoliths treated with advanced thin-layer coatings for durability and performance. They come with a 3-year warranty covering up to 100,000 km use, provided installation and maintenance conditions are respected.

• Certified to meet or exceed E24-103R homologation (European regulation).
• Manufactured under ISO 9001 quality standards.
• Included installation kits and detailed technical support.

Using original filters ensures compliance with emission legislation and optimal vehicle operation, while avoiding illegal tampering like DPF removal, which is prohibited for Euro 6 vehicles.
