Citroen C1 Catalytic Converter

The Citroën C1 catalytic converters primarily fit petrol 1.0L engines and vary by phase (Phase 1 or Phase 2), engine code (e.g., CFA, CFB (1KR), 1KR-FE), power output (68-69 hp, 50-51 kW), production years (2005-2014), and Euro emission standards (Euro 4 or 5). They mount at the exhaust manifold outlet and include original equipment (OE) references like 0342K0 and 171400Q010. Compatibility extends to Peugeot 107 and Toyota Aygo 1.0i models with matching engine codes and standards.

Catalytic converters for the Citroën C1 have a typical length of about 400 mm and weigh around 3.5 kg. They are homologated with E-Mark certification, compliant with Euro 4 or Euro 5 emission standards. The converters use high-quality monoliths coated with advanced thin-layer technology using rare metals for durability and optimal performance. They include accessories like upstream lambda sensors, mounting clamps, and sealing gaskets.

Replacing the catalytic converter on a Citroën C1 1.0 typically involves the following steps:

• Switch off ignition, engage handbrake, open hood, and disconnect the battery.
• Lift the front of the car on stands for safety.
• Remove the front bumper by unscrewing including 3 top screws, wing-mounted screws, and 5 screws at the bottom, then unclip all fasteners.
• Unplug the lambda sensor with a 13mm socket, separate the exhaust parts using a lever, then unscrew two nuts with a 13mm socket and remove the support bracing.
• Extract the old catalytic converter carefully through the radiator, remove old seals and heat shields.
• Install the new catalytic converter with new seals and protections, ensure proper tightening first by hand and then using a torque wrench, replace the lambda sensor using a 22mm wrench.

Using a direct-fit catalytic converter ensures compliance with anti-pollution norms. Always confirm engine code and vehicle production date for compatibility.

You can purchase Citroën C1 catalytic converters from specialist automotive parts providers offering OE equivalent quality. These sources typically provide detailed technical fiches confirming compatibility with various engine versions and Euro emission standards, including Phase 1 and Phase 2 petrol engines. Look for offerings that feature correct Euro 4/5 certifications and direct-fit models for the 1.0 petrol engines produced between 2005 and 2014. Online parts shops offer a range of references including FAO CB71378 and related mounting kits.

Choosing the correct catalytic converter is crucial for vehicle performance, emissions compliance, and durability. The right converter ensures:

• Proper filtering of harmful exhaust gases to meet Euro emission standards.
• Compatibility with engine power output and displacement to maintain engine efficiency.
• Correct fits and mounts that prevent exhaust leaks or sensor malfunctions.
• Legal compliance for passing technical inspections and environmental regulations.

Incorrect parts may lead to increased emissions, engine errors, and possible legal penalties.
