Mercedes GLK-Class Diesel Particulate Filter DPF X204 (2008-2015)

The Diesel Particulate Filter (DPF) on the Mercedes GLK-Class Diesel X204 (2008-2015) is an essential exhaust system component that captures fine particles from diesel engine exhaust gases to comply with Euro 5 emission standards. It ensures reduced harmful emissions from engines such as the OM651 2.2L diesel by filtering soot and particulates.

DPFs fit mainly these diesel GLK-Class X204 variants:

• 220 CDI (204.902): 2.2L, 170 HP, rear-wheel drive, OM651.916 engine, length 400 mm, weight 4.2 kg, Cordierite or Silicon Carbide material, Euro 5
• 220 CDI 4-Matic (204.984/204.997): 2.2L, 163-170 HP, all-wheel drive, weight 5.1 kg, length 400-590 mm, Cordierite
• 250 CDI 4-Matic (204.982/204.904): 2.2L, 204 HP, all-wheel drive, Euro 5
• 320 CDI 4-Matic (204.983): 3.0L, 224 HP, length 590 mm, weight 5.5 kg, Cordierite
• 200 CDI (204.901): 2.2L, 136 HP

DPFs typically weigh from 3 to 5.5 kg, are made of Cordierite or Silicon Carbide, and regenerate soot via automatic fuel injection reaching combustion temperatures above 600°C.

Recommended DPF replacement interval is every 120,000 km, or between 130,000 and 190,000 km to avoid failures according to European standards.

• Manual regeneration: Drive 25-30 minutes at 60-80 km/h in 5th or 6th gear to reach soot combustion temperature.
• Alternative regeneration: Use diagnostic tools such as VCDS or DPF cleaning additives.
• DPF cleaning products available include aerosols and liquids compatible with catalytic converter DPFs.

Proper maintenance extends the DPF life and prevents clogging due to short trips.

Common failure symptoms include:

• Increased fuel consumption
• Loss of engine power
• Check Engine light illumination with codes such as P244A related to DPF regeneration
• Black smoke emissions from the exhaust
• Reduced engine performance and overheating of the DPF
• Activation of limp mode or degraded vehicle operation

These signs require prompt diagnosis and maintenance to avoid further damage.

Frequent issues include clogging of the DPF due to short-distance driving that prevents passive regeneration. Solutions include:

• Using DPF cleaning additives to remove soot deposits
• Performing forced regeneration with suitable tools or software
• Replacing faulty sensors such as the wheel speed sensor to clear error codes
• Reprogramming or replacing Exhaust Gas Recirculation (EGR) valves or lambda sensors as advised by service centers

Regular maintenance and avoiding short trips help prevent clogging and prolong DPF life.

Various DPF spare parts are available, including:

• Standard and premium DPF models made of cordierite or silicon carbide
• Complete DPF units with mounting kits
• Parts with E24-103R certification to ensure compliance with Euro 5 regulations

These parts come with technical support and warranty, ensuring quality and compatibility for your vehicle.

To ensure optimal DPF performance and durability:

• Drive regularly at sustained speeds to enable automatic regeneration
• Use quality engine oil and replace oil regularly
• Follow vehicle manufacturer’s instructions for servicing and sensor replacements
• Avoid frequent short trips that prevent the exhaust system from reaching operating temperature
• Consult specialized garages for diagnostic and technical support if DPF warning lights appear

Good maintenance practices reduce pollution and prolong the DPF lifespan.
