Volkswagen Caravelle Catalytic Converter T4 (1990-2004)

The Volkswagen Caravelle T4 catalytic converter is a key component of the vehicle's exhaust system designed to reduce harmful emissions. It fits models produced between 1990 and 2003, including petrol engines (2.0L, 2.5L) and diesel engines (1.9TD, 2.4D, 2.5TDi). The catalytic converter helps meet Euro emission standards ranging from Euro 1 to Euro 4 depending on the engine type and year.

The catalytic converter on the Volkswagen Caravelle T4 is typically installed either in a central or front position on the exhaust line. Its exact location depends on the engine and model year, with lengths varying between 1030 mm and 1120 mm for petrol variants, and around 1140 mm for diesel models.

Most Volkswagen Caravelle T4 models, especially those built after 1990, were manufactured with catalytic converters to comply with emission standards.

• Petrol engines such as 2.0L and 2.5L usually include catalytic converters conforming to Euro 2, Euro 3, or Euro 4 standards.
• Diesel engines from 1996 onwards are equipped with catalytic converters or DPF (diesel particulate filters) for emission control.

To confirm if your specific T4 model includes a catalytic converter, check the VIN and engine codes or consult authorized technical resources.

Removing the catalytic converter is generally not recommended and often illegal, as it is a critical emission control device. While some claim slight improvements in performance or fuel mileage without the catalytic converter, this comes with significant environmental and legal consequences. Modern catalytic converters are designed to provide optimal engine performance while reducing harmful emissions.

Catalytic converters usually have a metal casing, often located near the engine or mid-section of the exhaust, and contain a honeycomb substrate inside. Silencers (mufflers) are typically larger chambers towards the exhaust tailpipe designed to reduce noise. If you tap the part and it sounds solid without loose bricks inside, it is likely a silencer rather than a catalytic converter.

Catalytic converters contain precious metals such as platinum, palladium, and rhodium within their monolithic honeycomb structure, which helps convert harmful gases into less toxic emissions. These metals make catalytic converters valuable for recycling and reuse. Additionally, because they are vital to vehicle emission compliance and environmental protection, maintaining functional catalytic converters is critical.

This value impacts scrap prices and influences the market for used and replacement catalytic converters.

Prices vary depending on the engine type, Euro standard rating, and whether the catalytic converter is new or used. Indicative prices for new, approved catalytic converters for models like the 2.5L 115 CV AVT petrol engine start around CHF 22 to CHF 468 excluding shipping. Used DPF or catalytic converters for diesel versions may be available around €165.

Krosfou offers high-quality catalytic converters with warranty, competitive pricing, and shipping options in Europe and internationally.

While some repair kits or mounting sets exist for catalytic converters, replacement is often the recommended solution to ensure compliance and performance. Proper installation including mounting, sensor wiring, and gasket replacement is critical to avoid leaks and ensure the system functions correctly.

• Replacement parts must fit the specific engine code and vehicle VIN.
• Your garage or repair workshop should handle installation according to manufacturer instructions and emission regulations.
• Krosfou provides direct factory support, installation guides, and warranty on quality catalytic converters.

Always use proper parts rated for your Volkswagen Caravelle T4 engine and follow local laws regarding catalytic converter maintenance and replacement.
