Citroen C5 Catalytic Converter

The catalytic converter for the Citroën C5 is a crucial exhaust system component designed to reduce harmful emissions. It transforms toxic gases from petrol and diesel engines into less harmful substances, helping the vehicle comply with European emission standards such as Euro 3, Euro 4, and Euro 5.

Catalytic converters are available for various generations of the Citroën C5, including C5 I (1998-2004), C5 II (2004-2008/2012), and later phases. They fit multiple petrol and diesel engines such as:

• 3.0 V6 petrol engines ES9J4S variants from 2001 onwards (Euro 3 standard)
• 1.6 HDi diesel engines (9HR, 9HY, 9HZ) mainly between 2004 and 2012
• 2.0 HDi diesel engines from early 2000s

Positions available include front left/right and rear, sometimes in short or long versions depending on model specifics.

Most Citroën C5 catalytic converters are manufactured using high-quality ceramics and INOX 409 stainless steel for durability and performance. They are certified with European standards such as E9-103R and E-Mark, ensuring compliance with strict emission regulations.

• High-grade ceramic honeycomb monoliths
• Stainless steel casing for corrosion resistance
• Coatings with rare metals for enhanced catalytic reaction efficiency

These materials help significantly reduce pollution and maintain engine efficiency.

Prices for new catalytic converters for Citroën C5 vary depending on engine compatibility, size and standard compliance. Current typical price ranges (excluding delivery) are:

• From approximately €159 for basic diesel models (e.g. 2.0 HDi)
• Up to over €430 for petrol 3.0 V6 high-spec models

Prices include 20% VAT and common discounts or promotions may apply.

To ensure exact fitment, verify your vehicle's engine code (e.g. ES9J4S, 9HR) and original equipment reference numbers. Technical data such as length, weight, and certification codes (E-mark, E9) are essential for proper selection.

• Check your vehicle identification number (VIN) with the supplier for confirmation.
• Installation kits are often included with the converter for secure mounting.
• OBD compliance is important for some petrol engines.

Always consult official documentation or professional support to confirm compatibility before purchase.

• Reduced engine performance or power loss
• Unusual exhaust smells or increased emissions
• Failed emissions inspection or technical control
• Rattling noise from under the vehicle due to broken internal components

If you experience these signs, consult a qualified mechanic for diagnosis and potential replacement.

Proper installation and maintenance are key to maximizing catalytic converter lifespan and function. Consider these guidelines :

• Use professional-fitment kits and avoid fitting without correct tools
• Confirm sensor and exhaust system compatibility, especially for OBD-compliant engines
• Regularly inspect the exhaust system for leaks or damage
• Adhere to manufacturer recommendations for emissions control systems
• Avoid prolonged short trips which can cause incomplete catalyst heating and damage

If in doubt, seek expert technical support or consult product installation manuals for your specific Citroën C5 model and engine type.
