Citroen C4 Catalytic Converter

The catalytic converter in Citroën C4 is an essential exhaust component that reduces harmful emissions such as CO, HC, and NOx by converting toxic gases into less harmful compounds. It is designed for petrol (VTi) and diesel (HDi, BlueHDi) engines and complies with Euro 4, 5, or 6 standards depending on the model and year.

Catalytic converters are specific to engine codes, power output, Euro norms, and exhaust configuration. Common compatible models include C4 Mk1, Mk2, Grand Picasso, C4 Cactus, and Aircross with petrol and diesel engines ranging from 1.2 to 2.0 liters. Variants cover front-mounted converters often fitted with the exhaust manifold and are not compatible with fuels like E85 or CNG.

Citroën C4 catalytic converters commonly feature:

• Monolithic ceramic or metallic substrates for standard exhaust systems
• Construction in stainless steel (INOX 409) for durability
• Includes necessary mounting fixations and sometimes a complete kit
• Certified with ECE or ABE homologation to meet European regulations
• Designed for OBD-equipped vehicles with specific engine displacements

They help maintain emission compliance without increasing engine performance.

You can order brand-new, high-quality catalytic converters manufactured in Europe with a 3-year guarantee directly from trusted providers specializing in automotive pollution-reduction technologies. They offer stainless steel INOX 409 converters fitted with advanced monolith technology for top performance and durability.

Yes, the onboard diagnostics (OBD) system should alert to malfunctions in the catalytic converter system. Warning lights such as the check engine light may illuminate for reasons including:

• Reduced catalytic converter efficiency or failure
• Faulty Lambda sensors or oxygen sensors affecting emissions
• Exhaust leaks or damaged connections before or after the converter

Regular diagnostic checks and maintenance are recommended to ensure the catalytic converter operates effectively, helping to maintain compliance with emission standards and smooth engine performance.

Choosing the correct catalytic converter involves considering:

• The exact Citroën C4 model, engine code, and power output
• Euro emission standard compliance (Euro 4, 5, 6)
• Fuel type compatibility (most are not compatible with E85, CNG, or LPG)
• Required position on the exhaust system (usually front mounted)
• OEM or equivalent certified part numbers to match your vehicle’s original specification

Using your vehicle’s VIN during search or consulting a professional garage helps ensure the correct converter type and installation fit the engine displacement and emissions equipment of your Citroën C4.
