Citroen Xsara Catalytic Converter

The catalytic converter in the Citroën Xsara is a key exhaust system component that reduces harmful emissions. It transforms toxic gases such as carbon monoxide, unburned hydrocarbons, and nitrogen oxides into less harmful substances like carbon dioxide, water vapor, and nitrogen using precious metals like platinum, palladium, and rhodium on a ceramic honeycomb substrate.

Some specific compatibilities include:

• Xsara Picasso 1.6 16v (N68, TU5JP4 engine, 109 PS, 2005-2007, Euro 4) with OEM numbers 1706E5, 10553 FV, 11249 CJ, 1609162580, and Walker 28041 reference.
• Xsara 1.4i fitted with original stainless steel catalytic converters.
• Xsara/Peugeot 306 2.0 16V (97 kW) with a Y-Pipe catalytic converter integrated, OEM 1705V0-946632.

Always verify compatibility by VIN or engine reference before purchasing to ensure proper fitment and performance.

The catalytic converter uses a chemical process called catalysis. For petrol engines, a 3-way catalytic converter converts:

• Carbon monoxide (CO) into carbon dioxide (CO₂)
• Hydrocarbons (HC) into water (H₂O) and CO₂
• Nitrogen oxides (NOₓ) into nitrogen (N₂) and CO₂

Diesel engines typically have a 2-way catalytic converter that converts CO and HC but does not treat NOₓ. Modern vehicles may also have a pre-catalytic converter positioned between the exhaust manifold and turbocharger for initial filtering.

Typical signs include:

• Engine warning light illuminated
• Loss of power and activation of limp mode
• Engine misfires or stalling
• Strong rotten egg smell (sulfur)
• Increased fuel consumption
• Failure during technical inspections with associated fines

Addressing these symptoms quickly helps maintain engine performance and emissions compliance.

Replacement typically involves removing the old catalytic converter and installing a new one compatible with your vehicle's engine type and model year. Technical manuals, illustrated guides, and video tutorials are available for DIY enthusiasts covering the process step-by-step. Installation kits and PDF guides are often provided with new catalytic converters.

• Ensure your car is at operating temperature for effective installation
• Use OEM or approved replacement parts
• Replace related components like Lambda sensors when indicated (typically after 80,000 to 100,000 km)
• Adhere to manufacturer instructions carefully

Professional installation by a qualified garage is recommended for warranty purposes.
