Toyota Land Cruiser Diesel Particulate Filter DPF J150 (2009-2023)

The Diesel Particulate Filter (DPF) in the Toyota Land Cruiser J150 (also known as Prado 150) is a crucial component designed to capture fine particles from diesel engine exhaust gases. Manufactured from cordierite, it weighs approximately 9.6 kg and measures about 950 mm in length. It helps the vehicle comply with Euro 5 emission standards by trapping soot and particulates, requiring regular regeneration to prevent clogging and maintain performance.

The DPF is compatible with several Toyota Land Cruiser J150 variants including:

• 3.0 D-4D (KDJ155_, KDJ150_) - 190 HP (140 kW), Euro 5, produced since 08/2009, max ash weight 60 g
• 3.0 TDi (1KD-FTV) - 163 HP, diesel fuel, DPF capacity approx. 1 litre
• 2.8 D-4D (GDJ150, GDJ155) - 177 HP (130 kW), since 06/2015

OEM reference for this range is generally 17410-11B31, designed for SUVs with Diesel D-4D/TDi engines.

Proper maintenance of the DPF includes:

• Regular regeneration by driving at 60-80 km/h for 25-30 minutes to burn off accumulated soot and ash at high temperature.
• Using diagnostic tools like VCDS to monitor soot and ash levels and trigger active regeneration if necessary.
• Applying specific DPF cleaner additives to dissolve soot and ash deposits and improve filter efficiency.
• Preventing ash accumulation above 60 g to avoid clogging and performance loss.

Following maintenance guidelines will extend the life of your DPF and maintain your vehicle’s emission compliance.

Replacement and cleaning options include:

• New DPF units manufactured with high-grade materials, stainless steel INOX 409, certified and guaranteed for 3 years.
• Various DPF cleaning additives available in aerosols (400-500 ml) for dissolving soot, with prices ranging accordingly.

Only new, original quality DPFs are recommended; avoid reconditioned or refurbished parts to ensure reliability and regulatory compliance.

Signs that your DPF may be clogged include:

• Increased fuel consumption
• Reduced engine power or performance
• Warning lights on your dashboard related to the exhaust or engine management
• Unusual smoke from the exhaust

Using diagnostic tools such as VCDS can also accurately measure soot and ash levels, helping to decide if regeneration or cleaning is needed.

When selecting a DPF, ensure compatibility by checking:

• Your vehicle's Euro 5 emission standard compliance.
• Engine code, such as KDJ150, 1KD-FTV, or GDJ150 depending on model and year.
• Year of manufacture because fitment and specifications may vary.

Correct matching avoids installation issues and ensures optimal performance and legal compliance.
