Mitsubishi Outlander Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) in Mitsubishi Outlander diesel vehicles captures soot particles from exhaust gases to reduce emissions. It requires periodic regeneration to burn off soot by injecting additional fuel at high temperatures, keeping the filter clean and efficient.

The DPF is mainly fitted on the Mitsubishi Outlander II (CW_W) models with diesel engines such as the 2.2 DiD (156 hp / 115 kW, years 2010-2012) and the 2.0 DiD 4WD (140 hp).

Frequent symptoms include:

• "DPF System Service Required" or "Check DPF System" messages indicating DPF clogging usually due to interrupted passive regenerations (common with short urban trips).
• Error code P252F, signaling "engine oil level too high," resulting from diesel fuel diluting the oil after several regeneration interruptions.
• An orange DPF warning light (exhaust pipe icon) illuminating on the dashboard.

Causes often involve short trips less than 15-20 minutes, low engine speeds, or poor-quality diesel fuel.

Recommended diagnostic and repair steps include:

• Drive for 15 minutes steadily at about 90 km/h to allow simple passive regeneration.
• If issues persist, a professional forced regeneration can be performed with a Mitsubishi-compatible scanner, taking 20-60 minutes.
• A complete procedure involves checking and changing engine oil if diluted with diesel, running regeneration via scanner, changing the oil and oil filter afterward, and resetting ECU codes.
• Professional DPF cleaning is usually more economical than full replacement and is advised over DIY methods to avoid costly errors.

Regular longer drives at higher engine speeds (above 3000 rpm) and using premium fuel help prevent clogging.

The DPF is generally recommended for replacement every 180,000 km or about 9 years, especially for the Outlander II 2.2 DiD 4WD models. Regular maintenance and regeneration extend its lifespan.

High-performance, original-quality diesel particulate filters and catalytic converters specifically for Mitsubishi Outlander diesel models are available from specialized suppliers. These parts:

• Are manufactured in Europe to meet strict regulatory standards (including E24-103R certification).
• Include a 3-year warranty covering up to 100,000 km of use.
• Are made with durable stainless steel (INOX 409) and advanced ceramic honeycomb monoliths for long service life.

Ordering direct from the factory ensures genuine quality without compromises on safety, performance, or compliance with emission rules.

DPFs come with a 3-year warranty limited to 100,000 km usage. Conditions include professional installation, following all manufacturer instructions, and avoiding short trips that prevent proper regeneration.

• Free returns are accepted within 30 days for unused parts in original packaging.
• Warranty does not cover failures caused by neglect or improper use, including clogged DPFs.
• Technical support is provided by email for installation guidance and troubleshooting.

Contact the supplier's technical support for details about warranty claims or to arrange returns properly.

Key preventative measures include:

• Regularly driving at sustained highway speeds (at least 90 km/h) for 15 minutes or more to facilitate passive regeneration.
• Using high-quality diesel fuel to reduce soot and residue accumulation.
• Keeping engine oil at correct levels and replacing it when contaminated, to uphold engine and DPF health.
• Avoiding frequent short trips where the engine does not reach optimal temperature for regeneration.

These practices help ensure your vehicle adheres to emission rules and maintains safety and performance.
