Peugeot 406 Catalytic Converter (1995-2004)

The catalytic converter in the Peugeot 406 is a metal component containing a ceramic honeycomb structure impregnated with precious metals, designed to reduce harmful emissions from the engine's exhaust gases. It plays a key role in controlling pollution and ensuring the vehicle meets Euro emission standards. Over time, it can become clogged or damaged which affects engine performance and triggers fault codes.

Peugeot 406 catalytic converters differ by engine type (diesel 2.0 HDi 107/110 CV or petrol 2.0 16v 136/137 CV), Euro emission standard (Euro 2, 3 or 4), presence of OBD, and body type (sedan, estate, coupe). It is essential to select the correct model reference to match the vehicle specifications exactly.

Check vehicle details such as engine code, production date, body type, and Euro standard. The catalytic converter's reference number must match your vehicle information.

• Use your car’s VIN or engine code to verify compatibility.
• Confirm presence or absence of OBD system and DPF if applicable.
• Compare the required dimensions and weight for your model.

Consult technical documentation or contact experts for measurements or sensor location if needed to ensure the right fitment.

Popular engines and related catalytic converter specifications include :

• Diesel 2.0 HDi 107/110 CV – Euro 2 to Euro 4, varying lengths 950-980 mm, weights 3.8-5.1 kg, multiple references to suit OBD presence or absence.
• Petrol 2.0 16v 136/137 CV – Euro 3 standard, OBD equipped, approximately 930 mm length, 3.2-3.4 kg weight, used on sedan, estate, and coupe models from 1999 to 2004.

Select components designed for your engine code and emission standard to maintain compliance and engine efficiency.

Common symptoms indicating catalytic converter issues include :

• Illumination of the engine warning light due to detected fault codes.
• Loss of engine power or poor acceleration.
• Higher oil consumption or exhaust overheating.
• Abnormal air-fuel mixture pressure or temperature readings.
• Unusual exhaust smell or visible black soot.

Early diagnosis and replacement help prevent permanent engine damage and improve emissions performance.

Driving with a faulty catalytic converter is not recommended. It can lead to :

• Increased exhaust emissions harmful to the environment.
• Potential damage to other components such as the engine or exhaust system.
• Failure to pass mandatory vehicle inspections or emissions tests.
• Possible lower fuel efficiency and reduced engine performance.

Replacing the catalytic converter promptly ensures normal vehicle operation and compliance with emissions regulations.
