Mercedes A-Class Catalytic Converter

A catalytic converter is a vital part of your Mercedes A-Class exhaust system designed to reduce harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides. It ensures your vehicle complies with Euro emission standards by converting these harmful gases into less harmful substances like carbon dioxide, nitrogen, and water vapor.

Catalytic converters are fitted on various Mercedes A-Class chassis such as W168, W169, W176, W177, and W246. They accommodate petrol, diesel, and hybrid engines with specifications depending on the engine type, power output, and production year, complying mostly with Euro 3 to Euro 5 emission standards.

Key specifications vary by model and engine type. Examples include:

• W176 (from 2012 diesel models): Integrated catalytic converter and DPF, Euro 5 standard, about 11.8 kg in weight, ref. FCD2988.
• W177 (recent hybrids): Catalytic converters for hybrid petrol-electric engines (M282.914).
• W168 (1997-2004): Catalytic converters for petrol A160 engines, Euro 3 compliance.
• W169 (2004-2012 diesel): Rear catalytic converters for A180 CDI, certified with E9-103R marking.

All models are European manufactured and come with a 2 to 3 year warranty when purchased new.

Catalytic converters use precious metal catalysts embedded in a honeycomb monolith structure to trigger chemical reactions that reduce harmful exhaust emissions:

• Convert carbon monoxide into carbon dioxide.
• Convert hydrocarbons into carbon dioxide and water.
• Reduce nitrogen oxides into nitrogen and oxygen.

Diesel models post-2011 commonly integrate the DPF (Diesel Particulate Filter) to trap particulate matter. Proper maintenance and recycling of these converters protect the environment and vehicle performance.

Common symptoms include:

• Reduced engine performance and power.
• Increased exhaust emissions or smell of sulphur.
• Warning lights on the dashboard such as the check engine light.
• Failed emission tests and increased fuel consumption.

Damage or clogging in the DPF may also affect other components like the EGR valve, frequently replaced together during service.

Prices vary depending on model, engine, and specifications, generally ranging from €250 to over €500. Krosfou offers high-quality, brand-new catalytic converters manufactured in Europe from stainless steel and high-grade ceramics, covered by a 3-year warranty.

• Warranty is limited to 100,000 km or 3 years.
• Includes mounting kits in many cases.
• Manufactured according to European and manufacturer standards with certification from TÜV SÜD.

These prices reflect factory-direct quality without compromising performance or vehicle compatibility.

Yes, recycling old catalytic converters is highly recommended both for environmental protection and recovering valuable metals. Specialist recycling programs accept used parts and provide buy-back options in some cases.

• Recycling supports reducing harmful emissions from the existing vehicle fleet.
• Krosfou offers collection services and buy-back programs for used parts.
• Proper disposal prevents harmful metal contamination in the environment.

Ensure to follow local regulations for disposal and recycling of automotive parts.
