Mercedes B-Class Catalytic Converter

The catalytic converter is a crucial component of the exhaust system in Mercedes B-Class vehicles. It transforms toxic exhaust gases into less harmful compounds through chemical reactions using precious metals like platinum, palladium, and rhodium. Typically located near the engine, it quickly reaches the ideal operating temperature of around 420°C to ensure efficient pollution control.

The main function is to reduce harmful emissions by converting carbon monoxide (CO), unburnt hydrocarbons (HC), and nitrogen oxides (NOx) into carbon dioxide (CO2), water (H2O), and nitrogen (N2). Gasoline models use a three-way catalytic converter treating CO, HC, and NOx, while diesel models use a two-way converter treating CO and HC, with NOx handled by other systems like SCR or EGR.

The converter contains a ceramic or metal honeycomb structure, coated with rare metals to catalyze oxidation and reduction reactions efficiently. Two lambda sensors, before and after the converter, monitor gas composition to optimize fuel-air mixtures and system performance.

Mercedes B-Class catalytic converters are tailored to fit these chassis series with references matching specific models and engines. Some suppliers offer complete catalytic convert systems, including exhaust pipes designed for perfect compatibility. Replacement tutorials and manuals help ensure proper installation.

• Designed to fit various petrol and diesel versions of the B-Class.
• Often paired with DPF filters on diesel models for fine particle reduction.
• Replacements restore vehicle performance and emission compliance.

Using a correctly selected catalytic converter ensures compliance with environmental regulations and quality standards designed for Mercedes vehicles.

Failure symptoms include:

• Loss of engine power and sluggish performance.
• Increased fuel consumption and emissions.
• Illuminated engine warning light indicating emission system issues.
• Unusual exhaust odors or abnormal noise from the exhaust system.

Failures typically result from clogging, poor air-fuel mixture, or ignition problems and may cause the vehicle to enter limp mode to protect the engine.

Catalytic converters contain valuable precious metals like platinum, palladium, and rhodium, making them targets for theft. Stolen catalytic converters lead to significant pollution increases and costly repairs for vehicle owners due to the complex replacement process and high part prices.

• Theft risks are high; always take preventive measures.
• Replacing stolen catalytic converters is expensive and time-consuming.
• Removing or tampering with the catalytic converter is illegal and affects vehicle compliance and performance.

Owners should report theft and seek professional replacement to restore emission standards and vehicle functionality.

Proper maintenance includes:

• Use high-quality unleaded petrol or diesel fuel depending on the engine type.
• Regular servicing of ignition and fuel mixture to avoid contamination and clogging.
• Periodic diagnostic checks with OBD systems to monitor sensor and gas emissions performance.
• Avoid short trips where the converter cannot reach operating temperature, which leads to fouling.

Never remove or bypass the catalytic converter as this reduces system efficiency, increases pollution, and is illegal in Europe.

The price varies based on the model year, engine, and specific catalytic converter system selected. Typically, prices range from several hundred euros upwards. Quality converters like those provided by Krosfou feature:
