Mercedes CLC-Class Catalytic Converter Cl203 (2000-2011)

The catalytic converter for the Mercedes CLC-Class CL203 is an essential emission control component designed to reduce harmful gases expelled from the car's exhaust system. It is available in different variants depending on the engine type and complies with Euro 4 to Euro 5 emission standards. This part helps the vehicle meet environmental regulations by converting toxic gases into less harmful emissions.

The catalytic converters for the Mercedes CLC-Class CL203 vary based on engine and model, including:

• CLC 180 Kompressor (1.8L petrol engine, M 271.946, 143 hp): Two versions – front catalytic converter meeting Euro 4 with E9 marking, and rear converter complying with Euro 5 and EG/ECE standards.
• CLC 220 CDI (Diesel, 150 hp, 2148 cc): Diesel oxidation catalytic converter with OEM references A2034902036 and A2034901436.
• CLC 230 and CLC 350: Featuring V6 and M272 E35 engines respectively, with dedicated catalytic converter types.

Each converter is adapted to the specific engine displacement and emission requirements of its respective model.

Key technical aspects include:

• Mounting position varies: front (Euro 4) or rear (Euro 5), depending on version.
• Compliance with European emission norms Euro 4 to Euro 5.
• European certification marking E9 on Euro 4 converters.
• Fuel types supported: petrol (Kompressor engines) and diesel (CDI engines).
• High-quality ceramic monoliths coated with rare metals for durability and performance.

These features ensure effective reduction of exhaust emissions and vehicle compliance with environmental standards.

Using a high-quality catalytic converter is vital for:

• Ensuring efficient conversion of harmful exhaust gases, reducing pollution from the vehicle.
• Maintaining engine performance and fuel efficiency.
• Guaranteeing compliance with emission regulations to avoid fines or vehicle restrictions.
• Protecting sensors and other exhaust components from damage.
• Enhancing vehicle longevity through durable materials like stainless steel and advanced ceramic coatings.

Quality converters are designed specifically for your vehicle model and engine type, ensuring optimal operation and longevity.

To ensure compatibility, you should provide:

• Your vehicle's exact model and year.
• Engine type and displacement (e.g., CLC 180 Kompressor 1.8L M 271.946 or CLC 220 CDI diesel).
• Original OEM part numbers if available.
• Vehicle Identification Number (VIN) for precise matching.

Consultation with a trusted supplier or technical expert can confirm the correct catalytic converter model based on these details, ensuring proper fitment and function.

Proper maintenance supports longevity and performance of the catalytic converter:

• Ensure the vehicle uses the correct fuel type: unleaded petrol for petrol engines and appropriate diesel for CDI engines.
• Replace oxygen and Lambda sensors according to manufacturer recommendations (typically after 80,000 to 100,000 km).
• Avoid engine malfunctions that could cause excess pollutants or overheating, which may damage the converter.
• Do not modify or damage exhaust system connections; use copper for any necessary joints and maintain system tightness.
• Limit short trips to allow the engine and catalytic converter to reach proper operating temperatures.

Following these tips helps prevent clogging and performance loss, ensuring emission compliance and vehicle health.

Key warranty and return conditions are:

• Most high-quality catalytic converters come with a 3-year warranty, limited to use under 100,000 km.
• Warranty covers defects if the catalytic converter is properly installed by certified professionals following all manufacturer guidelines.
• Free product returns are allowed within 30 days if unused, unmounted, and in original packaging.
• Returns beyond 30 days or products manufactured to order are generally not accepted.
• Warranty does not cover failures due to negligence or improper use, such as clogged units caused by poor maintenance.

Always retain the purchase invoice and follow installation instructions strictly to benefit from warranty coverage.

For further technical guidance and detailed product information, you can:

• Access professional catalogs which include full reference numbers and compatibility details.
• Contact technical support for assistance with installation, sensor positioning, and part compatibility using your VIN.
• Request installation manuals and receive support by email for accurate, documented advice.
• Utilize available analysis services to diagnose issues with used catalytic converters and recommend repair or replacement.
• Take advantage of loyalty programs and recycling initiatives for used parts to reduce environmental impact.

Reliable suppliers often provide these services to ensure the best quality and customer satisfaction with automotive emission parts.
