Renault Espace Catalytic Converter

A catalytic converter for Renault Espace is a crucial exhaust system component designed to reduce harmful vehicle emissions. It converts toxic gases such as hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) into less harmful substances using precious metals like platinum, palladium, or rhodium deposited on a honeycomb ceramic structure. It is compatible with Espace generations I to V, meeting emission standards from Euro 1 to Euro 6.

The catalytic converter chemically processes unburned exhaust gases using high temperatures (around 400-600°C) to convert:

• Hydrocarbons (HC) with oxygen into carbon dioxide (CO₂) and water (H₂O).
• Carbon monoxide (CO) into carbon dioxide (CO₂).
• Nitrogen oxides (NOx) into harmless nitrogen and oxygen.

Its honeycomb ceramic structure is coated with precious metal microparticles to maximize the reaction surface.

Common symptoms include:

• Illumination or flashing of the engine warning light indicating converter issues.
• Loss of engine power or performance, often related to clogged DPF or catalytic converter.
• Diagnostic trouble codes (DTC) detected using an OBD scanner, such as DF312 or DF308 specifically on some Espace models.

If faulty, replacement is recommended to avoid further damage and comply with emission regulations.

The catalytic converter should be selected based on:

• Renault Espace generation (I to V).
• Specific engine codes and versions, for example:
• Espace II 2.0 with engine codes J7R760 / J7R768.
• Espace II 2.2 dCi Euro 3 - rear catalytic converter reference 6025411752.
• Emission standard compliance (Euro 1 - Euro 6).
• Certain positions such as front or rear converters.

Always verify compatibility via engine code or VIN before purchase and install with intact sensors and gaskets.

The price generally ranges from approximately €140 to €563 depending on model, generation, and supplier. For example, Espace II catalytic converters can cost between €54 and €354. Pricing reflects compliance with emission standards and quality.

For purchase, opt for genuine European quality products that meet E24-103R certification to ensure legal and technical compatibility.

Key maintenance and replacement tips include:

• Check engine codes and perform diagnostics with an OBD scanner.
• Clean clogged DPFs or catalytic converters where possible using specific additives or professional cleaning, especially on Espace 4 models.
• Replace the catalytic converter when damaged or worn, using a compatible part by engine code and emission norm.
• Always replace related parts such as lambda sensors and gaskets during installation.
• Avoid counterfeit parts to maintain emission compliance and vehicle performance.

Professional installation is recommended to ensure correct fitting and performance.

Useful resources include:

• Online automotive parts catalogues with detailed compatibility for Renault Espace catalytic converters.
• Technical video tutorials explaining catalytic converter functionality, cleaning, and replacement specific to Renault Espace models.
• Automotive forums for user experiences and advice.
• Official vehicle reviews and repair manuals for ultra-specific model-year and engine code information.

Remember to use trusted European suppliers for genuine parts with proper certification.

Choosing a certified European catalytic converter ensures:

• Compliance with strict European emission regulations (E24-103R certification).
• High-quality manufacturing standards to guarantee durability and performance.
• Avoidance of counterfeit or non-compliant parts that may harm vehicle performance or cause legal issues.
• Better environmental protection by effectively reducing toxic emissions.
• Peace of mind with warranty backed by manufacturers adhering to rigorous testing procedures.

Certified products also maintain vehicle resale value and ensure passing emissions inspections.
