Mercedes V-Class W447 (2014-Today) Catalytic Converter

The Mercedes V-Class W447 catalytic converter is an essential exhaust system component designed to reduce harmful emissions from diesel vehicles, particularly models such as the V 220 d CDI, V 250 d CDI, and V 200 2.1 CDI 4-Matic. Compatible with OM 651.950 and OM 654.920 engines, these catalytic converters meet Euro 5b+ group III and Euro 6 emission standards for vehicles manufactured between 2014 and 2020.

Common model fits include:

• V 220 d CDI / d (163 HP, Diesel OM 651.950), up to mid-2016, Euro 5b+/6 compliant.
• V 250 d CDI (190 HP, Diesel OM 654.920), Euro 6 compliant from 2014 onward.
• V 200 2.1 CDI 4-Matic, Euro 6 compliant, model years 2015 to 2020.

Each variant features specific dimensions and reference codes for exact fitment.

Technical details vary by model but generally include:

• Diameter around 300 mm, height approx. 58.4 - 58.6 mm, with precise centring diameters.
• Weight ranges from about 2.67 to 17.06 kg depending on the model.
• Equipped with high-performance monoliths under TÜV-certified technology.
• Often integrated with Diesel Particulate Filters (DPF) for enhanced emissions control.

Examples of OEM reference codes include DELPHI BG3838, BOSCH 0 986 479 137, and others certified to ECE-R90 standards.

Catalytic converters are valuable because they significantly reduce harmful exhaust emissions, helping vehicles meet strict environmental regulations and lowering air pollution. They contain precious metals that catalyse chemical reactions to convert toxic gases into less harmful substances. Their functionality directly impacts car performance, fuel efficiency, and legal road use compliance.

• Essential for emission standard compliance (Euro 5b+, Euro 6)
• Often combined with DPF units to filter particulate matter
• High-quality construction increases longevity and vehicle performance

Choosing OEM or certified units ensures safety, reliability, and warranty coverage.

Prices vary by model and supplier, for example a V 200 W447 2.1 CDI 4-Matic catalytic converter can cost around 280 EUR including VAT. Pricing reflects the advanced stainless steel construction, high-quality monolith, and warranty coverage.

• V 220 d CDI catalytic converters range from affordable to mid-tier prices based on specifications.
• Prices include VAT and sometimes shipping costs depending on purchase location.
• Warranty terms typically last up to 3 years or 100,000 km.

Check current stock and prices with authorized suppliers ensuring genuine OEM or equivalent units.

Fitment depends on your vehicle’s specific engine model, manufacture year, and emission standard compliance. To ensure proper replacement:

• Verify your vehicle’s VIN and engine code against the catalytic converter specifications.
• Confirm compatibility with Euro 5b+ or Euro 6 standards applicable to your W447 variant.
• Check dimensions, mounting points, and sensor positions to match the original part.
• Consult technical documentation or contact support for precise assembly instructions.

Accurate fitment guarantees optimal exhaust performance, emission control, and warranty validity.

Maintenance includes regular inspections for damage, corrosion, or clogging. Replacement is necessary when performance drops or warning lights indicate failure.

• Use only high-quality replacement units matching your specific vehicle and engine.
• Installation should be performed by qualified technicians to ensure proper functioning and safety.
• Dispose of old catalytic converters responsibly, complying with environmental regulations.
• Systematic diagnostics help identify related exhaust or engine issues requiring attention.

Proper care and replacement increase vehicle lifespan and maintain emission standards.
