Audi A6 Catalytic Converter

Catalytic converters for Audi A6 vary depending on the generation (C6, C8, etc.), engine type (Diesel or Petrol), engine displacement, power output, and Euro emission standards. They come as new products manufactured with high-quality stainless steel and certified to meet or exceed European regulations.

Common engine types include:

• Diesel engines such as 40 TDI Mild Hybrid (C8), 3.0 TDI Quattro (C6), 2.5 TDI, and 2.7/3.0 TDI V6 24V
• Petrol engines such as 2.0L (2019-2023), 3.2 FSI V6 24V Quattro (2004-2008), and others

Each engine variant requires a catalytic converter matched to its technical specifications and Euro emission standards.

The catalytic converters use chemical reactions facilitated by precious metals such as platinum, rhodium, and palladium in a honeycomb monolith structure. These reactions convert harmful gases like carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbons (HC) into less harmful substances before they exit the exhaust system.

• They are often side-specific (left or right) and matched to the vehicle's gearbox type to ensure proper fit and function.
• The design and materials ensure durability and compliance with Euro 4 to Euro 6 standards.

This process helps significantly reduce vehicle emissions to meet environmental regulations.

Before purchase, check the following:

• Engine code (e.g., CDYA, AUK) to ensure fitment
• Generation code (C6 = 4F, C8 = 4A2)
• Dimensions such as length (ranges from approx. 630 mm to 1430 mm)
• Weight (typically between 3 and 5 kg)
• Emission standard compliance (Euro 4 to Euro 6, E-Mark certified)

Validating these details ensures correct compatibility and legal compliance.

Krosfou catalytic converters are recognized for superior quality and efficiency. They are manufactured in Europe using INOX 409 stainless steel and high-grade monoliths with advanced coating technology.

• Certified by TÜV SÜD Automotive, meeting or exceeding original equipment standards.
• Come with a 3-year warranty covering up to 100,000 kilometers.
• They contribute positively to vehicle performance and emission reduction.

Choosing such certified parts ensures durability, legality, and peace of mind.

To ensure perfect compatibility, you can:

• Check the vehicle identification number (VIN) or engine code with the supplier
• Match the exact model year, engine variant, and emission standard
• Consult technical details such as mounting position (left/right), gearbox type, and physical dimensions

Verification avoids fitting errors and ensures compliance with legal emission requirements.
