Mitsubishi L200 Diesel Particulate Filter DPF 4 (Iv) (2006-2015)

The Diesel Particulate Filter (DPF) in the Mitsubishi L200, including models like the 2.5 TD 4D56 (2005-2013 Euro 4) and Triton IV KA_T/KB_T (Euro 5), is a key component coupled with the catalytic converter. It filters fine particulate matter from exhaust gases through high-temperature regeneration. This system processes emissions in two stages: the catalytic converter burns particulates chemically, and the DPF captures and destroys the remaining residues.

Common symptoms of a defective or clogged DPF in the Mitsubishi L200 include:

• Illumination of the "DPF problem" warning light or Check Engine light on the dashboard.
• Loss of power and increased fuel consumption.
• Error codes like P1498, P2463 (DPF overloaded), P252F (DPF blockage), or codes related to differential pressure sensors and ECU faults.
• Abnormal differential pressure readings (negative or too high), which can be checked at different engine speeds.
• Contradictory error messages related to transmission, immobilizer, or boost leaks.

Common causes include:

• Excessive soot accumulation due to short or urban driving preventing natural regeneration at around 550°C.
• Engine oil dilution by diesel fuel, especially in Japanese engines like the 4D56, which blocks future regenerations if oil level rises above maximum.
• Faulty sensors (differential pressure, exhaust temperature), cracked or damaged DPF substrate, or pierced hoses.
• Repeated forced regenerations without solving the root cause, often worsening issues like boost leaks or overheating.
• Other problems such as boost leaks, internal ECU faults, or contaminated oil.

Proper diagnosis is essential to avoid further damage.

Diagnosis involves:

• Reading live data for soot load and differential pressure (stability is expected; low values may indicate sensor or substrate issues) using OBD tools at varying rpm (e.g., 3000 RPM).
• Using a manometer to verify sensor readings against actual pressure.
• Checking engine oil level and performing oil changes if excess oil is found, common especially on L200 Triton models.
• Confirming proper installation coupled to the catalytic converter, with original temperature sensors.
• Ignoring certain error codes related to automatic transmission if manual intervention is planned.

Recommended steps include:

• Natural regeneration: Driving at high engine speed (>3000 RPM) to reach 550°C for soot burning, with use of specific DPF additives.
• Forced regeneration: Using diagnostic tools to trigger regeneration and check pressure sensors before proceeding, ensuring correct oil levels.
• DPF cleaning procedures: Draining excess oil, applying cleaning fluids, then running the engine at high rpm to expel soot with confirmed pressure drops, and using lubricants like WD40 to loosen tight sensors.
• Resetting related systems including DPF exchange status and oil level data to enable new regenerations.
• Replacement with certified aftermarket DPFs made of cordierite compatible with Euro 5 standards, using recommended references and repair tutorials.
• Preventive measures: Avoid short trip driving, monitor oil quality and levels, and use appropriate additives for DPF care.

Relevant models and standards include:

• The 2.5 TD 4D56 engine models from 2005 to 2013 complying with Euro 4 regulations.
• The Triton IV models (KA_T, KB_T) meeting Euro 5 standards.
• DPFs made with cordierite material on Euro 5 Triton models; references like OE 1583A085 and aftermarket MIF109 are standard.

DPFs are factory coupled with catalytic converters and equipped with OE temperature sensors for optimal performance.
