Citroen C3 Catalytic Converter

The catalytic converter is an essential exhaust system component for the Citroën C3. It reduces harmful emissions by converting pollutants from the engine exhaust into less harmful substances, helping the vehicle comply with Euro 3, 4, 5, or 6 standards. Positioned usually before the exhaust pipe or attached to the exhaust manifold, it plays a key role in pollution control and vehicle environmental compliance.

Catalytic converters are available for multiple Citroën C3 variants, including:

• C3 Phase 1 with 1.4 16V 88 HP engine (code KFU/ET3J4), petrol, Euro 4 max, until 2010
• C3 Phase 1 with 1.4 i 73 HP (code KFV/TU3A or TU3JP), petrol, Euro 3/4, until 2009
• C3 III with 1.2 VTi SX (code HMZ/EB2F), petrol, Euro 6, from 2016
• C3 1.0 engines (codes ZMZ or EB0), petrol, Euro 5/6 between 2009-2015

Always check compatibility via VIN or engine code to ensure the correct catalytic converter option for your vehicle.

Common features of Citroën C3 catalytic converters include:

• Positioned at the front, before the exhaust pipe or attached to the exhaust manifold
• Designed for petrol engines with 4 cylinders and 2 valves per cylinder in some variants
• Produced with high-quality stainless steel and ceramic monoliths conforming to European standards and OBD regulations on applicable models
• Lengths vary from approx. 470 mm to 800 mm, weights between 3 and 4.13 kg depending on model

These components come new with assembly parts included or available as options to facilitate installation.

Yes, on many Citroën C3 catalytic converters, the oxygen probe (lambda sensor) is replaceable. This allows for maintenance or replacement without changing the entire catalytic converter unit, which can be a cost-effective option when the sensor itself is faulty or aging.

• Check your specific engine and converter model for sensor compatibility
• Professional installation is recommended to ensure proper sensor positioning and functionality

Consult the vehicle manual or a trusted technician if unsure about this option.

Prices vary depending on the model, engine type, and Euro standard but expect quality new catalytic converters to come with a warranty, typically up to 3 years or limited to 100,000 km usage. Purchasing from reputable suppliers ensures certified quality parts compliant with European regulations and often accompanied by mounting kits for easier installation.

• Beware of offers for refurbished or reconditioned parts; always opt for new certified catalytic converters
• A genuine warranty provides confidence in performance and durability

Always check the warranty terms and conditions before purchase.

To ensure precise compatibility and fitment:

• Provide the VIN (Vehicle Identification Number) to your supplier for confirmation
• Check the engine code (such as ET3J4, TU3A, HMZ/EB2F, ZMZ, EB0) and phase/version of the vehicle
• Verify the Euro emission standard matched by the catalytic converter
• Confirm sensor positions and mounting dimensions where applicable

Correct match avoids driveability issues and warning lights.

Common warning signs include:

• Check engine light or catalytic converter warning codes (e.g., P0420)
• Reduced engine performance or power loss
• Unusual engine noises or emissions smell
• Failed emissions testing or visible smoke from exhaust

If you experience these symptoms, have your catalytic converter and exhaust system inspected and replaced if necessary by professionals using quality parts.

Choosing new and certified catalytic converters ensures:

• Compliance with Euro emission standards (Euro 3, 4, 5, or 6) for your vehicle
• High-quality manufacturing in stainless steel and advanced ceramic substrates for durability
• Restored or improved engine efficiency and reduced emissions
• Warranty coverage for peace of mind and longer-term value
• Direct support and reliable technical advice from the manufacturer or authorized dealers
• Contributions to pollution reduction and environmental protection
