Mitsubishi Grandis Diesel Particulate Filter DPF (2003-2011)

The Diesel Particulate Filter (DPF) on the Mitsubishi Grandis is an essential anti-pollution component installed on diesel engines compliant with Euro 4 standards. Specifically designed for the 2.0 DI-D Turbo Diesel engine (engine code BWC with 140 hp) produced between February 2007 and March 2010, it captures fine soot particles from exhaust gases to reduce harmful emissions.

The DPF traps soot particles from diesel combustion while letting exhaust gases pass through. It requires periodic regeneration to burn off accumulated soot at high temperatures (about 550-600 °C) because normal urban driving does not produce sufficient exhaust heat (around 150 °C at 50 km/h) to self-clean the filter.

• Spontaneous regeneration : Occurs naturally during long highway drives at sustained speeds.
• Engine-controlled regeneration : The engine control unit triggers regeneration by post-injection of fuel, EGR cut-off, or turbo adjustments to raise exhaust temperature.
• Risks : If the filter becomes heavily blocked through frequent short urban drives, incomplete regeneration may damage the DPF and cause engine oil dilution. Special low-SAPS oil and regular oil changes are required.

The Mitsubishi Grandis 2.0 DI-D model utilizes a standard DPF without an integrated catalytic converter and does not use the Eolys additive system common in some other diesel engines.

• DPF replacements are available for Mitsubishi Grandis models manufactured between 02/2007 and 03/2010.
• Average labour time to replace the DPF is approximately 42 minutes.
• The system is sensitive to frequent city driving, which may accelerate filter clogging.

Always consult a professional for exact pricing and part compatibility according to your vehicle’s VIN and engine code.

Common symptoms of a clogged DPF include:

• DPF warning light illuminated on the dashboard.
• Loss of engine power or acceleration.
• Increased fuel consumption.
• Vehicle operating in limp mode (reduced engine performance).

These issues often arise from repeated short urban trips, incorrect engine oil, or failed regeneration cycles.

Maintenance and repair options include:

• Forced regeneration in a workshop using cleaning additives or specialised machines, suitable when clogging is moderate.
• Replacement of the DPF if cleaning is no longer effective or if the filter is severely damaged.
• DIY replacement guides and videos are available showing the basic tools and steps needed to remove and install the DPF on the Grandis.

Preventive care involves driving at higher engine speeds for over 20 minutes approximately every 500 km and using low-SAPS oil to protect the filter.

High-quality DPFs offered by reputable suppliers typically come with a warranty of up to 3 years, limited to a usage not exceeding 100,000 kilometres. Products are brand new, not refurbished, and meet or exceed European regulatory standards. Always check warranty terms and conditions at the time of purchase.

To select the correct DPF, use your vehicle's registration details, engine code (e.g., BWC for the 2.0 DI-D), and model year to verify compatibility. Professional suppliers provide catalogs and support to help you find the exact part number. Always confirm part references before purchase.

• Use official vehicle documentation or dealer references.
• Consult online product databases authorized for your car model.
• Consider contacting technical support for help with sensor and hose positioning if needed.

Additional resources include:

• Technical explanations about DPF operation and regeneration methods.
• Step-by-step repair manuals and video tutorials for cleaning or replacing DPFs on Mitsubishi models.
• Community forums to exchange experiences about Grandis DPF issues and solutions.
• Authorized supplier catalogs providing up-to-date product references and warranty details.

For the latest updates, always check professional garage websites or Mitsubishi official sources. Avoid unreliable aftermarket or refurbished parts to ensure compliance and durability.
