Peugeot 308 Catalytic Converter

The Peugeot 308 catalytic converter is an essential component of the exhaust system designed to reduce harmful emissions such as hydrocarbons, carbon monoxide, and nitrogen oxides. It uses precious metals like platinum, palladium, and rhodium to trigger chemical reactions on a ceramic substrate at high temperatures, converting toxic gases into less harmful substances.

Common symptoms of catalytic converter failure include:

• Engine warning light illumination
• Loss of engine power
• Strong unpleasant odors from exhaust
• Error codes related to oxygen (Lambda) sensors
• Internal cracks or damage, possibly causing exhaust leaks

These issues can lead to poor engine performance and increased pollution.

Yes, certain Peugeot 308 diesel models (e.g., 1.6 HDi) allow catalytic converter cleaning without removal using specialized products aimed at oxidizing catalyst deposits. This can help restore efficiency. However, cleaning is not always possible or effective for all models and conditions.

Maintenance tips include regular vehicle servicing, checking sensors, and avoiding short trips that prevent the catalytic converter from reaching optimal operating temperature.

Key Peugeot 308 models with specific catalytic converter requirements include:

• 308 II 1.6 BlueHDi 120 (2013-2021, Euro 6 standard) - OE references like 9803803780
• 308 GT THP 1.6 16V (2008-2013) - some performance downpipes available removing OEM catalytic converter
• 308 II Euro 4 versions - downpipes integrating Euro 4 catalytic converters with two oxygen sensor slots

Always check compatibility by vehicle VIN and engine code before purchase.

General replacement steps include:

• Disconnecting oxygen (Lambda) sensors
• Removing the exhaust line sections (upper and lower)
• Replacing metal gaskets if needed
• Installing the new catalytic converter and reassembling with clamps
• Resetting engine error codes to clear warning lights

DIY tutorials and manuals for Peugeot 308 models are available to assist with this process, but professional assistance is recommended to ensure proper fit, sensor installation, and sealing.

Purchasers can choose from:

• Brand new OEM-quality catalytic converters manufactured under strict standards with TÜV certification and 3-year warranty
• Compatible catalytic converters designed to meet or exceed manufacturer specifications
• Performance downpipes for specific GTI models that remove the OEM catalytic converter (requires compliance with regulations)

Always select catalytic converters certified and matched to your engine displacement, Euro emission standard, and vehicle model for optimal performance and legal compliance.

To ensure proper choice:

• Check your vehicle identification number (VIN) for precise engine and model details
• Refer to original equipment manufacturer (OEM) part numbers when available
• Consult documentation or professional advice to confirm Euro emission standard compliance
• Consider engine type (diesel or petrol) and fuel specifications

Incorrect parts can cause engine issues, sensor errors, or fail emissions testing.

Used catalytic converters contain valuable metals which determine their price. Selling used units involves:

• Evaluating condition and metal content
• Finding certified recycling or buying businesses
• Providing details like model, year, and part condition

Prices vary based on metal market value and converter condition. For exact valuation and sale, contact authorized buyers who specialize in catalytic converter recycling.
