Function And Benefits
The catalytic converter reduces harmful exhaust emissions (CO, hydrocarbons, NOx) by converting them into less harmful gases via a precious-metal coated ceramic substrate. Being integrated into the exhaust manifold, this unit provides fast light‑off (quick heating) which improves emissions control during cold starts. Replacing a damaged or contaminated unit restores emission performance, reduces exhaust smell, and can eliminate related fault codes and limp‑home modes.
Common Symptoms Indicating Replacement Is Needed
- Check Engine Light with emission-related fault codes (e.g., catalyst efficiency)
- Loss of engine power, hesitation or reduced acceleration
- Unusual sulfur/rotten-egg smell from the exhaust
- Rattling noise from the converter (broken substrate)
- Failed emissions test
Why This Part Fails Most Often
Catalytic converters typically last many years but can fail prematurely due to: thermal overload from unburned fuel or persistent misfires (melting or cracking of the substrate), contamination by engine oil or coolant leaks that coat the catalyst, physical damage from impacts or road debris, and internal degradation of the catalytic coating. In integrated manifold units, heat cycling and vibration accelerate wear.
Installation Recommendations
- Work on a fully cooled exhaust system to avoid burns. Support the vehicle securely and use appropriate lifting equipment.
- Disconnect the battery if you will be handling electrical components such as oxygen sensors.
- Remove oxygen sensors before detaching the manifold/converter to avoid sensor damage. Inspect sensors and replace if necessary.
- Replace all gaskets and sealing rings when reinstalling to ensure a proper seal. Use anti-seize on sensor threads where recommended by manufacturer.
- Inspect surrounding components (heat shields, exhaust studs, EGR piping) and replace corroded fasteners to ensure correct torque and sealing. Apply manufacturer torque settings where available.
- After installation, clear fault codes and perform a road test to confirm normal operation and absence of leaks or new fault codes.
How Replacement Is Performed (High-Level)
- Allow exhaust to cool. Safely raise and support the vehicle.
- Disconnect and remove oxygen sensors and any nearby sensors or heat shields obstructing access.
- Unbolt the exhaust manifold catalytic assembly from the cylinder head and the rest of the exhaust system (retain or replace nuts/studs as needed).
- Remove the old unit, fit new gaskets, and install the replacement part. Reinstall sensors and heat shields.
- Tighten fasteners to manufacturer specifications, start the engine, and check for leaks and diagnostic trouble codes.
Notes For Buyers
This listing includes original part numbers to help you confirm fitment: 0342L3, 1608916280, 1688263080. Used unit removed from a vehicle with approximately 68,000 km — a practical choice when seeking an OEM-style replacement at lower cost than a new original part.
Search Tips
Customers often find this part by searching the product codes above or the vehicle models (Citroën C1, Peugeot 107) combined with engine reference 1.0 i / 1KR. Use these identifiers when comparing fitment or ordering replacement gaskets and sensors.
