Mercedes CLA-Class Diesel Particulate Filter DPF C117 (2013-2019)

The Diesel Particulate Filter (DPF) in the Mercedes CLA-Class C117 is a crucial component of the diesel exhaust system designed to capture and remove fine particulate matter emitted by the engine. It helps reduce harmful emissions to comply with Euro 5 and Euro 6 environmental standards.

The DPF C117 is mainly compatible with the Mercedes CLA 220 CDI / d 2.1 diesel engine equipped with the OM 651.930 engine, producing 177 HP. This filter supports a maximum ash load of up to 60 grams.

The DPF uses two main materials:

• High-performance Silicon Carbide (SiC)
• Alternative Cordierite, which is less dense

Dimensions vary by model, with lengths of 990 mm, 1050 mm, or 1070 mm and weight between 7.2 kg and 8.9 kg. The filter is located on the exhaust line, after the catalytic converter.

Common signs that your DPF may be clogged include:

• Increased fuel consumption
• Reduced engine power
• Illumination of the "Check Engine" light
• Error code P2463 indicating filter blockage
• Abnormally high soot filling rates (up to 291% according to diagnostics)

To avoid major issues, it is recommended to replace the DPF between 135,000 and 185,000 kilometers. Regular monitoring of the filter condition can help ensure optimal engine performance and reduced emissions.

Yes, there are several options:

• Chemical cleaning without removal: Products like Xenum DPF Cleaner, Motul Diesel DPF Cleaner, PETEC DPF Cleaner (silicone-free), Valvoline DPF Cleaner, and Cartechnic aerosol can be used.
• Natural regeneration: Driving at 60 to 80 km/h for 25 to 30 minutes helps reach optimal temperature to burn off soot and ash.
• Assisted regeneration: Using diagnostic devices such as VCDS or Topdon Artidiag800BT to force filter regeneration.

After proper cleaning and regeneration, the filter soot load can decrease dramatically, restoring engine performance and reducing differential pressure in the exhaust system.

Replacement DPFs for the C117 come with mounting hardware included and are fully compatible with the vehicle's OBD system. Modern versions may include an integrated catalytic converter to ensure compliance with emission standards.

The DPF plays a vital role by trapping and removing fine particulates from diesel exhaust gases. This reduces polluting emissions and helps your vehicle meet strict environmental regulations, thereby contributing to cleaner air and better engine performance.

Choosing an original, high-quality DPF ensures reduced fuel consumption, maintained power, and long-lasting performance in your Mercedes CLA coupe.
