Peugeot 206 Catalytic Converter

The catalytic converter in a Peugeot 206 processes exhaust gases to reduce harmful pollutants through chemical reactions. Exhaust gases flow from the engine via the manifold where a first redox catalysis (with rhodium or platinum) converts NOx into nitrogen and oxygen. Then, an oxidation catalysis (with platinum and palladium) burns unburned hydrocarbons (HC) and carbon monoxide (CO) into CO2 and water (H2O). It contains ceramic honeycomb plates coated with precious metals like platinum, palladium, and rhodium. The optimal operating temperature is around 420°C, which is why it is located close to the engine. Below this temperature, it can clog and become blocked.

Common symptoms indicating catalytic converter issues on a Peugeot 206 include:

• Opaque smoke emitted from the exhaust
• Metallic noise or strong vibrations under the floor
• Loss of power during acceleration and frequent stalling
• Difficulty starting the engine and power loss, especially noted on 1.4 HDI models

The replacement is feasible with proper tools and some preparation (use of a penetrant recommended).

• Unscrew the lambda sensor using a 22mm wrench or special socket.
• Remove the screws attaching the catalytic converter to the exhaust pipe.
• Unbolt 4 nuts on the manifold using a 13mm socket with extension.
• Unscrew the chassis brackets (16mm socket + ratchet wrench).
• Remove the catalytic converter and metal gasket.
• Compare old and new parts, lubricate new screws.
• Install new gasket on manifold, position catalytic converter, tighten nuts and chassis bolts.
• Place sealing gasket, connect to pipe with new screws and springs.
• Reinstall lambda sensor with copper grease, remove any stickers before operation.

Note: Several users have confirmed successful repairs following this process.

Recommended maintenance includes:

• For 206+ model: dismantle turbo outlet flange and clean internally; after a 5-minute running break-in, expect improved starting and gear shifts with less friction load and initial white smoke followed by normal condensation.
• For 206 1.4 HDI: cleaning to restore power and optimize performance in the 50-70 km/h speed and 2000-3000 rpm ranges.
• Removing thermal screens by loosening 6-8 screws/nuts on various parts and removing protective covers for access.

Peugeot 206 catalytic converters are available online with competitive pricing. It is essential to verify the part compatibility by engine type, such as 1.4 HDI or 1.4 i 75cv models.

Benefits include tiered discounts for bulk orders, free shipping, free returns within 30 days on unused products, loyalty points, buy-back of used parts, and direct factory technical support.

Diagnosing catalytic converter problems involves observing signs such as exhaust smoke, noise or vibrations, and loss of power. It is recommended to test the OBD diagnostics for lambda sensor errors and exhaust backpressure before removal or replacement. Videos and tutorials from trusted sources like YouTube can help in step-by-step testing and cleaning.

For advanced technical assistance, Krosfou offers analysis of used parts to identify failure causes like installation leaks, sensor problems, impact damage, or temperature issues. Always ensure compliance with security, confidentiality, and usage conditions when troubleshooting.
