Mitsubishi Outlander Diesel Particulate Filter DPF

A Diesel Particulate Filter (DPF) in the Mitsubishi Outlander is a key component of the exhaust system designed to reduce fine particulate emissions from diesel engines. It traps soot and particulate matter from the exhaust gases, helping to meet stringent pollution standards like EURO5 on models such as the 2.2 DI-D (4N14) and 2.0 4WD.

DPFs are available for various Mitsubishi Outlander diesel models, notably:

• Outlander 2.2 I-D 4WD (engine 4N14) from 09/2010 to 09/2012, including the DPF and rear pipe, compliant with EURO5 standards.
• Outlander 3 2.0 4WD 150cv, with specific replacement procedures.

Always check compatibility with your vehicle's VIN or model specifications before purchase or installation.

The DPF operates through two main phases:

• Filtration: The filter captures soot particles from the exhaust gases.
• Regeneration: The trapped soot is automatically burned off at high temperatures to clean the filter, either passively during normal driving or actively triggered by the vehicle systems.

This process helps limit harmful emissions and maintain engine performance.

Common signs of DPF issues include:

• Warning lights related to the DPF or exhaust system on the dashboard.
• Loss of engine power or the vehicle entering limp mode.
• Increased fuel consumption.
• Unusual exhaust smells or smoke.

These symptoms can result from DPF clogging due to failed regeneration, often exacerbated by short trips or low-speed driving.

To prevent or fix clogging:

• Regularly drive the vehicle at speeds and conditions that allow the DPF to regenerate fully.
• Avoid frequent short urban trips that prevent filter cleaning.
• Consider professional cleaning methods like ultrasonic cleaning or using specific additives.
• Replace the DPF if cleaning is no longer effective or damage occurs.

Consult a qualified garage for proper diagnosis and service, as incorrect handling can void warranties or cause further damage.

The cost of a new DPF for Mitsubishi Outlander diesel models varies mostly due to specifications and suppliers, generally ranging between €165 and €925. Labour costs for replacement, for example on an Outlander 3 2.0 4WD 150cv, can take around 1 hour 33 minutes.

• Prices depend on EURO5 standard compliance, inclusion of pipes, and garage fees.
• Always obtain a quote from your trusted garage before proceeding.

Note: Krosfou offers new original DPFs made from high-quality stainless steel with a 3-year warranty and superior performance certified by TÜV Sud.

For genuine and high-quality DPFs, select suppliers who offer certified parts with warranties, such as Krosfou, ensuring:

• New, factory-made DPFs with stainless steel INOX 409 technology.
• Technical support and fitment guides.
• Access to fast delivery and professional discounts for mechanics and garages.

Maintenance and cleaning services can also be sought from specialised garages equipped to diagnose and service DPFs properly.

If your vehicle displays a DPF warning or enters limp mode:

• Immediately avoid short trips and try driving at higher speeds to encourage passive regeneration.
• Schedule a diagnostic check using OBD at an authorised garage to determine the cause.
• Follow recommended actions from the diagnosis, which may include cleaning the DPF or replacing faulty sensors.
• Do not ignore warning signs as this can lead to increased damage and repair costs.

Maintaining the DPF system properly ensures your Outlander remains compliant with emission regulations and runs efficiently.
