Description
Catalytic converter for CITROËN C1 and PEUGEOT 107 with 1.0 i 50 kW engine. Exhaust manifold with integrated catalytic converter. Removed from a vehicle with a genuine 68,000 km mileage.
Product Overview
High-quality used exhaust manifold with an integrated catalytic converter designed for Citroën C1 and Peugeot 107 fitted with the 1.0 i (50 kW) engine. This complete manifold/catalyst assembly includes the substrate and flange ready for direct replacement on compatible vehicles. The unit retains original OEM fitment and mounting points, making it a practical and cost-effective repair option for workshops and experienced DIYers.
Why Choose This Catalytic Converter
- Direct fit for specified models — reduces modification time and avoids custom exhaust work.
- Includes integrated manifold for simplified installation compared with separate pipe-mounted converters.
- OEM part numbers listed for easy matching with service manuals and parts catalogs.
- Suitable for mechanics and knowledgeable DIY technicians looking for a reliable replacement at a lower cost than new OEM parts.
Function And Symptoms Of Failure
The catalytic converter reduces harmful emissions by converting CO, HC and NOx into less harmful gases. When the catalyst is failing or clogged, common symptoms include reduced engine performance, loss of power under load, increased fuel consumption, rattling noises from the converter body, and sometimes a persistent check engine light with fault codes related to catalyst efficiency or backpressure.
Typical Lifespan And Common Causes Of Failure
Catalytic converters generally last many tens of thousands of kilometers, often exceeding 100,000 km under normal conditions. Failures can occur earlier due to factors such as chronic rich running or misfires (which overheat or melt the ceramic substrate), contamination from oil or coolant, physical damage from road debris or corrosion, and thermal shock from rapid cooling of a very hot catalyst. Incomplete combustion or long idling periods can accelerate clogging.
Installation Recommendations
- Prepare the vehicle: Work on a cooled exhaust system; raise and support the vehicle safely. Use penetrating oil on fasteners if needed.
- Replace Gaskets And Fasteners: Always fit new exhaust gaskets and use the correct grade of bolts/nuts where required. Exhaust flange hardware is often seized — inspect and replace as necessary.
- Oxygen Sensor Handling: If an O2 sensor is fitted to the manifold, remove it carefully and reinstall or replace with the correct sensor. Apply anti-seize on sensor threads where appropriate, avoiding contamination of the sensor tip.
- Verify Engine Health: Resolve underlying engine issues (misfires, rich running, oil/coolant leaks) before fitting the new converter to prevent immediate recontamination or damage.
- Tightening And Alignment: Align flanges before final torque and follow the vehicle manufacturer’s torque specifications from the workshop manual. Check for exhaust leaks after installation.
- Recommended For: Professional fitment by a workshop or experienced DIY technicians with appropriate tools (jack stands, torque wrench, O2 sensor socket).

Most Common Reason For Failure
The most frequent cause of premature catalytic converter failure is engine-related issues that allow unburned fuel or oil to enter the exhaust (misfires, worn ignition components, fuel system faults, or oil burning). This leads to overheating, substrate melting or contamination and eventual clogging or internal breakage.
Notes For Purchasing
Match the listed product codes with the vehicle’s parts catalog or service literature to confirm compatibility. The listed unit is a used original equipment assembly removed from a vehicle at approximately 68,000 km; visual inspection for external damage and sensor threads is recommended before installation.
