Peugeot Boxer Catalytic Converter

The catalytic converter in the Peugeot Boxer is an essential part of the exhaust system. It transforms toxic gases such as hydrocarbons, carbon monoxide (CO), and nitrogen oxides (NOx) into less harmful substances like carbon dioxide (CO2), nitrogen (N2), and water vapor through chemical reactions catalyzed by precious metals including platinum, palladium, and rhodium.

The catalytic converter operates on chemical principles involving two main reactions:

• Reduction of nitrogen oxides (NOx) to nitrogen (N2) using rhodium and platinum in an oxidoreduction reaction.
• Oxidation of unburned hydrocarbons and carbon monoxide (CO) into carbon dioxide (CO2) and water using platinum and palladium.

It functions best at around 420°C and activates from 200°C. Internally, it has a ceramic or metallic support, oxygen sensors before and after, and temperature and NOx sensors to regulate exhaust gases. Diesel models often have this catalytic converter combined with a DPF and SCR system that uses AdBlue to neutralize NOx emissions.

Catalytic converters are used on Peugeot Boxer diesel and multifuel utility models from generations II and III since 1994. Typically, these models comply with Euro 5 and Euro 6 standards and have integrated DPF and SCR technologies for effective emission control.

Replacement is recommended if the catalytic converter is clogged due to low-temperature driving or poor fuel quality, or if it is failing. Common symptoms include:

• Check engine light activation.
• Loss of engine power.
• Unusual sulfur or rotten egg odors.
• Unstable idling or increased fuel consumption.

Replacement can be done DIY with proper tools, such as wrenches and jacks, by removing the exhaust section containing the catalytic converter and reinstalling a compatible new or original part.

Common issues include:

• Theft due to valuable precious metals inside.
• Clogging from repeated cold starts or excessive engine oil consumption.
• Sensor malfunctions leading to poor engine control and higher emissions.

Symptoms are typically unstable idle, black smoke emission, and increased fuel consumption.

The cost varies depending on the specific model, new or used condition, and source. Prices generally range from 300 to 1,500 euros. It’s important to choose a part compatible with your engine and emission standards (e.g., 2.2 HDi).

• Consider installation costs if not doing a DIY replacement.
• Check warranty and product certifications for quality assurance.

Catalytic converters contain precious metals such as platinum, palladium, and rhodium, which catalyze chemical reactions to reduce harmful emissions. These metals are rare and valuable, making catalytic converters targets for theft and a valuable recyclable item.

• These metals enable effective conversion of pollutants into less harmful substances.
• Their rarity and efficiency contribute to high market value.

That is why vehicle security and proper maintenance are important for catalytic converters.

To maintain or replace your catalytic converter properly, consider the following:

• Choose original or certified parts designed and manufactured in Europe with certified quality standards.
• Ensure replacement parts match your vehicle’s engine specifications and emission norms.
• Replace sensors and related exhaust components as recommended to avoid ECU errors.
• Avoid short trips that prevent the catalytic converter from reaching optimal operating temperature.
• Use quality unleaded fuel and perform regular engine maintenance like timely oil and spark plug changes.

Professional installation is recommended for warranty coverage and optimal performance. For delivery, customers can typically expect standard or express options within Europe and worldwide.
