Peugeot 2008 Catalytic Converter

The catalytic converter is a vital part of your Peugeot 2008's exhaust system that reduces harmful emissions through a chemical process called catalysis. Exhaust gases pass through ceramic honeycomb plates coated with precious metals like gold and platinum.

For petrol engines, the catalytic converter performs three main reactions:

• Converting nitrogen oxides into carbon dioxide
• Transforming carbon monoxide into carbon dioxide
• Turning unburnt hydrocarbons into water vapor and carbon dioxide

It only becomes fully effective once it reaches temperatures above 400 degrees Celsius, which is why short trips or cold engines reduce its efficiency.

Typical signs of catalytic converter wear or failure include:

• Illumination of the engine warning light on the dashboard
• Significant loss of engine power
• The vehicle operating in limp or degraded mode

A common fault code associated is P0420, indicating reduced catalytic converter efficiency. This can be caused by cracks in the catalytic converter or oxygen sensor issues.

The Peugeot 2008 typically uses two catalytic converters:

• The pre-catalytic converter, located between the exhaust manifold and the downpipe, which pre-filters gases for improved efficiency
• The main catalytic converter, which completes the filtration of exhaust gases

This dual-catalyst system ensures optimal reduction of emissions in your vehicle.

Replacement requires specific tools and careful steps to avoid damage:

• Tools needed: 13 mm, 15 mm, 22 mm, and 30 mm wrenches; deep socket; lever bar; and WD-40 lubricant
• Key steps for removal include detaching upper nuts, disconnecting oxygen sensors, releasing bolts, and applying lubricant on seized parts
• Reinstallation involves cleaning surfaces, installing new exhaust manifold gaskets, fitting the new catalytic converter, securing heat shields, and reconnecting sensors

Following these steps carefully will ensure successful replacement and optimal functioning.

A common issue is cracking which leads to:

• Audible rumbling or grinding noises inside the vehicle
• Increased oxygen levels in exhaust gases triggering P0420 fault code
• Reduced catalytic converter efficiency and performance

These cracks affect oxygen sensor readings, causing discrepancies between actual and expected engine mixture values.

The replacement process and parts are similar for models including:

• Peugeot 207 and 208
• Peugeot 308 and 3008

This shared design ensures cross-model compatibility for many catalytic converter components.

Catalytic converters contain precious metals such as platinum and gold embedded in the honeycomb ceramic structure. These metals catalyse harmful emissions into less destructive gases, making catalytic converters valuable components in vehicle exhaust systems. Their metal content also makes them sought after for recycling and scrap value.

The price of a Peugeot 2008 catalytic converter varies depending on the model year and supplier. Factors affecting cost include the quality of materials, manufacturing standards, and compliance with emission regulations. For accurate pricing and purchase conditions, it is recommended to check with authorized suppliers or manufacturers directly.

Always consider the benefits of choosing high-quality catalytic converters that meet or exceed regulatory standards for reliable performance and environmental compliance.
