Mercedes GL-Class Catalytic Converter

The catalytic converters are mainly available for Mercedes GL-Class generations X164 (2006-2012) and X166 (2012-2015), focusing on diesel engines 3.0 CDI and 4.0 CDI with 4-Matic systems. Notable models include GL320 X164 3.0 CDI 4-Matic (2006-2009), GL350 X164 3.0 CDI 4-Matic (2009-2012), and GL350 X166 3.0 CDI 4-Matic (2012-2015), among others.

Catalytic converters for these models meet E-Mark certification and Euro 4 standards for 2006-2009 3.0 diesel engines. They weigh approximately 4.6 kg (e.g., for GL320 CDI X164 3.0 4-Matic). Their main function is to reduce pollutant emissions and maintain engine performance, usually combined with a diesel particulate filter (DPF). Estimated lifespan ranges from 80,000 to 120,000 km, varying with usage and maintenance.

Signs that a catalytic converter may need replacement include :

• Difficulty accelerating.
• Increased fuel consumption.
• Illuminated engine warning light.

Some Mercedes GL-Class models, especially BlueTEC versions like GL 350 BlueTEC 4MATIC X164 II, integrate advanced technologies :

• Selective Catalytic Reduction (SCR) system to reduce nitrogen oxide emissions.
• DPF (Diesel Particulate Filter) to trap fine particulates.
• Compliance with upcoming Euro 6 standards and improved fuel efficiency (e.g., 7.4 L/100 km consumption).

These advanced emission control systems optimize both environmental impact and vehicle performance.

Reliable information is available through specialized automotive parts websites and the official Mercedes platforms. Key sources include :

• Authorized online catalogs and FAQs for product specifics and compatibility checks.
• Technical data sheets for engines like OM642 with DPF details.
