Volkswagen Crafter Catalytic Converter

The Volkswagen Crafter catalytic converter is an essential exhaust system component, primarily for diesel TDI engines like the 2.5L 5-cylinder. It transforms harmful exhaust gases including CO, HC, and NOx into less toxic substances such as CO2, H2O, and N2 through chemical reactions catalyzed by precious metals like platinum, palladium, and rhodium. Usually integrated near the exhaust manifold and paired with a Diesel Particulate Filter (DPF), it works with oxygen (lambda) sensors to optimize fuel-air mixture for combustion efficiency and emissions control.

The Volkswagen Crafter mainly utilizes two types of catalytic converters depending on engine type:

• Two-way catalytic converters for diesel engines (Crafter TDI) treating CO and HC, with NOx handled separately via SCR or EGR systems.
• Three-way catalytic converters for petrol engines that treat CO, HC, and NOx simultaneously.

The catalytic converter includes high-quality ceramic honeycomb structures inside a metal casing and is equipped with sensors to monitor temperature and gas composition, ensuring high efficiency.

Common issues include oxygen sensor failures, clogging due to improper fuel mixtures, overheating, and poisoning (e.g. lead or sulfur contamination), which lead to symptoms such as:

• Check engine light illumination and specific OBD codes (P0420, P0430)
• Reduced engine power and performance
• Strong sulfur or rotten egg smell from exhaust
• Increased fuel consumption and potential engine misfires

Catalytic converter theft is also a concern due to the precious metals inside.

Prices for new, original catalytic converters vary widely depending on the Crafter model year (2006 to 2026) and engine type (2.0L to 2.5L TDI/CR). Typical price range is approximately €28 to €635 excluding VAT.

• New original converters come with a 3-year warranty and quality certification.
• Used or scrap converters have variable value based on precious metal content.
• Replacement should be done after professional diagnosis using OBD tools for accuracy.

Installation usually requires sensor replacement and proper fitment near the engine or DPF system.

Catalytic converters contain precious metals such as platinum, palladium, and rhodium which act as catalysts for harmful gas conversion. These metals have significant industrial value, making catalytic converters targets for theft and valuable as scrap. Their efficient performance relies on these metals’ catalytic properties, contributing to controlled emissions and compliance with strict Euro emission standards.
