Peugeot 2008 Catalytic Converter

The catalytic converter in the Peugeot 2008 is a crucial part of the exhaust system that transforms toxic gases from the engine into less harmful compounds through chemical reactions. It mainly targets engines such as the 1.2 VTI petrol engine. The catalytic converter uses precious metals like rhodium, platinum, and palladium to reduce nitrogen oxides (NOx) and oxidize unburnt hydrocarbons (HC) and carbon monoxide (CO) into carbon dioxide (CO2) and water (H2O). It operates optimally at a minimum temperature of 420°C to ensure effective pollutant conversion.

The catalytic converter is positioned close to the engine on the Peugeot 2008, typically near the exhaust manifold. In some multi-cylinder models, a pre-catalytic converter is present before the main catalytic converter, helping to start the chemical reactions at a higher efficiency. The system then continues through silencers for noise reduction.

Common symptoms indicating a clogged or damaged catalytic converter include :

• Opaque smoke from the exhaust
• Metallic noises or vibrations beneath the vehicle
• Loss of engine power and acceleration issues
• Engine stalling and illumination of the engine warning light, often with error code P0420
• Visible cracks especially on the Peugeot 2008 1.2 VTI model after dismantling

These signs usually require immediate diagnostic and potential replacement.

Main causes of catalytic converter failure are :

• Build-up of soot or hardened sealant upstream causing blockage
• Melting of the ceramic monolith due to excess fuel (over-fueling)
• Obstruction preventing contact between precious metals and exhaust gases
• Corrosion or seizure of mounting bolts and oxygen sensors

Proper maintenance and addressing engine faults quickly help avoid such failures.

Replacement involves several detailed steps and special tools. A typical DIY guide based on Peugeot 2008 and similar models includes :

• Removing O2 sensors with 22mm socket and disconnecting wiring
• Removing bolts and nuts securing the catalytic converter (sizes 13mm, 15mm, 30mm)
• Applying penetrating oil like WD-40 to seized bolts
• Extracting the catalytic converter carefully to avoid damage
• Installing new manifold gaskets, reusing O2 sensors if still functional, applying copper grease to bolts
• Reassembling all parts and testing for leaks and proper engine start

For models like Peugeot 2008 1.2 VTI, replacement is necessary when cracks are detected after removal.

Important considerations include :

• Choose original equipment manufacturer (OEM) quality or certified compatible parts
• Ensure compatibility with your Peugeot 2008 model and engine displacement
• Check for E24-103R certification to guarantee compliance with European emission regulations
• Replace oxygen sensors during catalytic converter replacement if necessary (usually after 80,000 to 100,000 km)
• Reset the engine control unit (ECU) after installation to clear error codes
• Beware of theft risks due to precious metals inside the catalytic converter; some parts feature anti-theft markings

Costs vary between approximately 300 to 1000 euros for a new unit.

Catalytic converters contain precious metals such as platinum, palladium, and rhodium which are essential for the chemical reactions that reduce toxic emissions. These metals are rare and have high market value, making catalytic converters both valuable for recycling and targeted for theft.

• Precious metals act as catalysts in oxidation and reduction reactions
• Ensure compliance with emission standards by reducing NOx, CO, and unburnt hydrocarbons
• Their presence makes the catalytic converter costly compared to other exhaust parts

The investment in a high-quality catalytic converter improves vehicle environmental performance and complies with regulations.

The cost of a new catalytic converter for the Peugeot 2008 generally ranges from 300 to 1000 euros depending on the model, year, and engine specification. Prices include the precious metals treatment and high-quality manufacturing standards required for compliance and durability.

• Costs are influenced by the engine displacement and emission standard
• OEM or certified replacement parts generally cost more but offer better reliability
• Professional installation and sensor replacement may add to the total cost

Price details can vary with availability, shipping, and vendor but generally fall within this range for Peugeot 2008 models from 2013 to 2023.

Always refer to the vehicle's main reference and model details before purchasing.
