Dacia Sandero Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) on Dacia Sandero diesel engines captures harmful fine particulate matter (soot) from exhaust gases after the turbo. It functions by two main cycles: particle collection, which forms a layer of soot inside the filter, followed by regeneration, where the accumulated soot is burned off via combustion. This regeneration process is managed electronically by sensors monitoring temperature, pressure, and an integrated catalytic converter to ensure optimal engine performance and emission control.

DPFs are mainly fitted on Dacia Sandero diesel 1.5 dCi engines (e.g., K9K612 engine code). Notable models include:

• Sandero II 1.5 dCi (B52) with 75 hp, Euro 5 standard, produced between 2010 and 2012.
• Sandero Stepway 1.5 dCi models with 68 or 90 hp, especially models from 2013 to 2019 equipped with DPF and sometimes also EGR systems.

Before purchasing or replacing a DPF, it is important to verify the Euro norm and engine code. All DPFs are E-mark homologated under regulations CEE-ONU 103.

Common signs of DPF problems include:

• Illumination of the engine warning light (orange) along with a multifunction red warning.
• Loss of engine power or reduced torque.
• DPF warning light indicating possible soot clogging.
• Confusion between EGR and DPF issues as some models prioritize DPF without a visible EGR valve.

These symptoms are typically caused by soot accumulation blocking the filter.

DPF cleaning and diagnosis involve:

• Using a specialized DPF/EGR additive added at one third of the fuel tank volume.
• Driving at sustained 4000 rpm in 3rd gear or 110-120 km/h in 4th gear for approximately 20 minutes to activate regeneration.
• Checking the effectiveness of cleaning over time to confirm soot reduction.

If cleaning fails, professional diagnostics with an OBD scanner and pressure sensor readings are recommended to ascertain DPF condition.

Replacement options include fitting new original DPF units specifically designed for Dacia Sandero 1.5 dCi models. These come with mounting kits and a 24-month warranty. Prices vary, but typical replacement costs start around £1300 plus VAT depending on model and garage rates.

• Ensure correct model and engine code matching before purchase.
• Professional installation is necessary for correct sensor integration and system function.

Consult your trusted garage for accurate pricing and installation service.

DPF regeneration is primarily an automatic process managed by the vehicle’s electronic control unit using inputs from temperature probes and pressure sensors. It activates combustion inside the DPF to burn off soot deposits and maintain engine performance.

Manual forced regeneration can be performed by driving under specific conditions such as maintaining 4000 rpm in 3rd gear or around 120 km/h in 4th gear for at least 20 minutes, sometimes with the use of additives to enhance soot burning efficiency.

• This manual driving method helps if the automatic regeneration cycle fails or the filter becomes heavily clogged.

Regular driving at highway speeds can support automatic regeneration and extend the DPF lifespan.

To maintain your DPF and ensure long-lasting performance, consider the following advice:

• Avoid frequent short-distance trips that prevent the engine from reaching optimal temperature for DPF regeneration.
• Use recommended oil types and change oil regularly as per manufacturer specifications.
• Perform occasional sustained high-speed driving to promote DPF regeneration.
• Use approved DPF cleaning additives as preventive maintenance.
• Have your vehicle regularly serviced to check pressure sensors and injection system to prevent soot build-up.

Following these guidelines will optimize driving performance and reduce risk of clogging and power loss.

For genuine quality DPF products and technical support compatible with Dacia Sandero diesel models, sourcing from reputable manufacturers with European homologation is important. Krosfou offers brand-new stainless steel DPFs with a 3-year warranty, complying with strict performance and emission standards, backed by technical expertise.

• Installation manuals and technical advice are available for professional fitting.
• Experienced garages can provide proper diagnosis and servicing recommendations.
• Forums and online communities may offer additional driving tips and regeneration experiences.

Always verify compatibility by engine code and Euro norm before ordering parts to ensure correct fit and function for your car model and year.

Consult professionals for diagnostics and avoid unverified reconditioned parts to maintain vehicle reliability and emission compliance.
