Dacia Logan Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) is a component in the exhaust line of a Dacia Logan diesel vehicle, designed to capture harmful particles produced by the diesel engine combustion process. It helps the vehicle meet environmental standards by filtering fine particulate matter from exhaust gases.

DPF is fitted on various Dacia Logan diesel models including:

• Dacia Logan MCV dCi 90 (engines K9K626, K9K628, K9K629)
• Dacia Logan 1.5 dCi 75hp (engines K9K626, K9K628, K9K629)
• Dacia Logan Break models 2016 and onwards with diesel engines

These filters comply with EURO 6 emission standards, ensuring maximum environmental conformity.

Common problems include clogging due to particulate buildup, especially during short or low-speed trips. Symptoms often are:

• DPF warning light illumination after 300-500 miles
• Loss of engine power and inability to accelerate
• Frequent need for filter cleaning
• Recurrent clogging despite repeated interventions

When particulate accumulation exceeds 24 grams, the clogging becomes critical forcing corrective action.

DPF regeneration cleans accumulated soot by burning it off. There are two types:

• Natural Regeneration: Occurs during long, constant-speed driving conditions, such as highway trips, allowing the exhaust temperature to burn off soot.
• Forced Regeneration: Performed by diagnostic tools when natural regeneration is insufficient, especially on dCi 90 models.

It is important to wait and drive accordingly to allow proper regeneration and avoid clogging.

Yes. Cleaning can be done professionally but may need several attempts as it is often temporary if driving patterns remain the same. Replacement with a new original-quality DPF is also available and recommended for persistent problems.

Additionally, an engine decarbonising service can reduce DPF clogging by limiting the creation of particulates at source.

To prevent recurrent DPF problems on your Dacia Logan:

• Prefer long journeys at steady speeds such as on motorways rather than frequent short urban trips
• Allow time for natural DPF regeneration by maintaining appropriate driving conditions
• Consult a specialised diesel diagnostic garage if problems persist, to check for sensor faults or other issues

Proper driving and maintenance can extend the life of the DPF and maintain engine efficiency.

DPF and related sensor issues both trigger warning lights and performance loss. Diagnosis requires specialised diagnostic tools to read fault codes from the vehicle’s engine control unit. A garage specialising in diesel engines can distinguish between a clogged DPF and a faulty sensor for accurate repair.

• Sensor faults can mimic DPF clogging symptoms but don’t improve with cleaning or regeneration
• DPF clogging generally occurs after certain mileage and under specific driving conditions

Professional diagnostics are recommended for a correct and specific intervention.
