Mercedes Viano Diesel Particulate Filter DPF W639 (2003-2014)

The Diesel Particulate Filter (DPF) for the Mercedes Viano W639 is a key exhaust system component designed to reduce harmful diesel emissions by capturing and storing particulate matter from the exhaust gases before they are released into the atmosphere. It helps meet stringent European Euro emission standards.

The DPF is suitable for multiple diesel engines in the W639 model including:

• OM651.940 2.1-2.2 CDI engines with power ranging from 95 to 163 BHP, compliant with Euro 5 standards.
• OM642.890 3.0 CDI engine with 224 BHP, compliant with Euro 4 standards, sometimes fitted as a second DPF on models from 2006-2011.

The DPF features important specifications such as :

• Weight around 4.6 kg
• Length approximately 1135 mm
• Made from durable Cordierite material
• Includes a sensor hole on the left, driver side
• Manufactured in Europe meeting strict quality and environmental standards
• Supplied with a mounting kit (KIT462)

This ensures compatibility and efficiency for emission control and exhaust flow.

Suitability depends on the engine model and year of manufacture. Before purchase, check :

• Your Viano’s engine type (e.g., OM651.940 or OM642.890)
• Emission standard compliance (Euro 4 or Euro 5)
• Physical measurements like length and sensor positioning
• The exact OE reference or compatible spare part numbers

Accurate matching is essential for correct fitment and performance.

Maintaining your DPF properly after installation is critical to :

• Extend the operational lifespan of the filter
• Maintain optimal filtering efficiency and reduced exhaust emissions
• Prevent common issues such as clogging or sensor malfunctions
• Regularly add cleaning additives designed for DPF systems

Good maintenance supports compliance with environmental regulations and performance.
