Mercedes ML-Class Catalytic Converter

The Mercedes ML-Class catalytic converter is an essential component of the vehicle's exhaust system. It reduces harmful emissions by converting exhaust gases like carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances. This part is compatible with multiple ML-Class generations and various petrol and diesel engine models.

The catalytic converters are designed for several ML-Class generations including :

• ML 320 (W163, petrol engine M 112.942, 3.2L from 1998)
• ML 320 CDI 4-matic (W164, diesel engine OM 642.940, 3.0L)
• ML 300 CDI 4-matic (W164, diesel engine 3.0L)
• ML 280 CDI and ML 270 CDI (W164 diesel engines)
• ML 350 variants including TDCDi engines

The exact catalytic converter fitment depends on the vehicle model, year, and engine type.

For example, the catalytic converter for the ML 320 CDI 4-matic (W164) typically has :

• Lengths of 310 mm or 400 mm
• Weight between 3.3 kg and 4.6 kg
• Euro 4 emissions compliance
• Rear assembly position
• Ceramic material construction
• Available with or without particulate filter (DPF)
• CE/CEE conformity marks including E9-103R for European vehicles

These specifications ensure the catalytic converter meets performance and legal requirements.

Selecting the proper catalytic converter involves checking :

• The engine TECDOC number (e.g., OM 642.940 for W164 diesel)
• The exact model and year of your ML-Class vehicle
• Required emission standard compliance (typically Euro 4)
• Whether your vehicle is equipped with a DPF (particulate filter)
• OBD compatibility for emissions diagnostics
• Physical dimensions like length and weight
• Inclusion of mounting hardware or need for separate purchase

Verifying these details ensures proper fit and function.

Some catalytic converters come as a complete kit including mounting hardware and fixings. However, others may require you to purchase the necessary installation parts separately. It is important to review the product details carefully before purchase to confirm if mounting accessories are included.

Mercedes ML-Class catalytic converters comply with strict emission and quality standards, including :

• European CE/CEE certification
• E9-103R marking for European vehicle conformity
• Euro 4 emission standards as a minimum requirement

These standards ensure the catalytic converters meet legal and environmental regulations, contributing to reduced air pollution.

For precise technical data and specifications regarding the Mercedes ML-Class catalytic converter, consult :

• The official vehicle service manual
• Certified spare parts suppliers with detailed catalogues
• Specialist automotive websites and databases focused on exhaust components

These sources help ensure you get the correct part based on your engine and model specifications.

Using an OEM or approved catalytic converter ensures :

• Optimal engine and exhaust system performance
• Compliance with environmental emission laws
• Durability and correct fit to your vehicle’s exhaust pipe
• Proper functionality of the onboard diagnostic systems (OBD)
• Avoidance of illegal emissions and potential fines

Choosing quality OEM converters protects your vehicle, environment, and legal compliance.

Always ensure your catalytic converter meets the specific requirements for your Mercedes ML-Class model for the best results.
