Mercedes Vito Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) in Mercedes Vito vans, primarily W639 and W447 models, is an exhaust system component designed to capture fine diesel particles. Its main role is to reduce harmful emissions in compliance with Euro 4 and Euro 5 standards. It is commonly fitted on 2.1 CDI and 2.2 TD CDI engines produced from 2003 onwards.

A clogged or failing DPF may cause several issues including :

• Increased fuel consumption
• Loss of engine power and performance
• Illumination of the "Check Engine" warning light
• Excessive soot and ash buildup inside the filter (up to 60 g of ashes allowed on W639)

Addressing these symptoms promptly can avoid more serious exhaust system problems.

DPF cleaning and regeneration methods include :

• Passive/active regeneration by driving at 60-80 km/h for 25-30 minutes to reach operating temperature (~600°C) which helps burn off soot
• Using diagnostic tools such as VCDS to initiate forced regeneration
• Applying professional cleaning additives or treatments designed for DPF systems to prevent clogging

These methods are essential maintenance services for keeping diesel exhaust systems functioning properly and prolonging filter lifespan.

Replacement is recommended when :

• The DPF cannot be regenerated despite cleaning attempts
• Irreversible clogging or damage is detected
• After reaching approximately 130,000 to 200,000 km to avoid unexpected breakdowns

Replacing the DPF with a quality genuine or approved filter ensures emissions compliance and vehicle performance.

Typical characteristics for DPFs used on Vito W639 2.1 and 2.2 CDI engines include :

• Emission standards : Euro 4 and Euro 5 compliant
• Length : Usually between 920 mm and 1540 mm (commonly 1050 to 1140 mm)
• Weight : Ranges from 4.2 to 9.5 kg, typical weight about 7 kg
• Material : Silicon carbide or cordierite ceramic substrate made with high-quality monoliths
• Sensor positioning : Usually right or left probe hole for pressure sensors

Exact fitment and features may vary; verifying sensor location and mounting kit compatibility is important before purchase.

For reliable Mercedes Vito diesel particulate filter replacements, it is advised to choose high-quality DPFs that :

• Are manufactured with durable stainless steel (INOX 409) and superior ceramics
• Have certifications from reputable bodies such as TUV SUD
• Are new original parts, not reconditioned or refurbished
• Include all necessary mounting kits and sensor fittings

Choosing such filters ensures longevity, compliance with emissions, and optimal van performance on the road.

DPF prices vary depending on the model, brand, and type :

• Range from approximately €25.49 to €694
• Many suppliers offer free shipping on orders over a certain value
• Return policies often allow returns within 200 days if unused and unmounted

Purchasing from specialized dealers ensures genuine parts with performance guarantees and proper support.

Proper maintenance of your Mercedes Vito DPF involves :

• Regularly driving at highway speeds (60-80 km/h) to enable passive regeneration
• Using quality diesel fuel and additivess designed to reduce particulate buildup
• Monitoring warning lights and engine performance closely
• Addressing any fault codes promptly with diagnostic tools
• Consulting professional mechanics for scheduled inspections

Following these steps helps prevent costly repairs, maintain engine efficiency, and reduce emissions for your commercial vehicle's future service life.

If severe clogging occurs, seek garage diagnostics and avoid removing or tampering with the DPF as this may be illegal and harmful to your van's emissions system.
