Peugeot 406 Catalytic Converter (1995-2004)

The catalytic converter in a Peugeot 406 is an essential exhaust system component that reduces harmful emissions by converting toxic gases such as hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) into less harmful substances like carbon dioxide (CO₂) and water vapor (H₂O). It operates effectively at exhaust gas temperatures of 400–800°C, requiring 30-60 seconds of warm-up for optimal performance.

Peugeot 406 catalytic converters are designed to fit various engine types and model variants including:

• 2.0 16V Petrol (1999–2004), engines codes RFR, RFN producing 137 hp.
• 2.0 HDi Diesel (1998–2004), engine code DW10 with approx. 110 hp, featuring stainless steel construction.
• 3.0 V6 Petrol for coupé models, known for catalytic converter clogging issues.

Aftermarket stainless steel catalytic converters are available with modern technology for durability, but adaptation and longevity should be considered carefully.

Replacing the catalytic converter yourself involves the following:

• Raising the vehicle safely and removing lambda sensors.
• Cutting off seized bolts and detaching the old catalytic converter.
• Installing the new catalytic converter using appropriate gaskets and clamps.
• Necessary tools include a torque wrench, cutter, and anti-seize spray.
• Typical replacement duration is 2 to 4 hours for an experienced DIYer.

Consult detailed tutorials and videos specific to Peugeot 406 for step-by-step guidance. Always check the lambda sensors for faults during replacement.

Common symptoms of catalytic converter issues include:

• Loss of engine power and increased fuel consumption.
• Unusual sulfur-like odor and check engine light activation.
• Unstable engine idling and diagnostic trouble codes (e.g., P0420).

Causes include age-related clogging, overheating, improper fuel mixtures, and excessive soot especially in HDi diesel engines.

Diagnosis involves exhaust backpressure testing and OBD scanning. Beware of low-cost parts that may not meet quality or compatibility standards.

Reliable online sources offer Peugeot 406 catalytic converters tailored for specific engines (e.g., 2.0 16V or 2.0 HDi). For best results:

• Search using specific engine codes and years for accuracy.
• Verify OEM references and certifications (like E24-103R).
• Choose products manufactured in Europe, preferably with stainless steel construction for durability.
• Consult community forums for user experiences and installation tips.

Delivery and return policies usually include free returns within 30 days if unused, and a 3-year warranty limited to 100,000 km use.

Unblocking or cleaning a catalytic converter is sometimes feasible using chemical or mechanical cleaning methods. However:

Cleaning may be a temporary solution and not always effective for severely clogged or damaged catalytic converters. If symptoms persist, replacement is recommended.

• Diagnostic checks with pressure gauges and OBD scanning help determine severity.
• Chemical decarbonization products may help with mild deposits.
• Professional advice is recommended before attempting cleaning or removal.
• Removing the catalytic converter is illegal and not advised due to environmental and legal considerations.

High-quality catalytic converters for Peugeot 406 typically come with the following guarantees:

• 3-year warranty valid for up to 100,000 km usage.
