Audi 100 Catalytic Converter C4 (1990-1994)

The Audi 100 C4 catalytic converter is an essential component of the vehicle's exhaust and emission system, designed to reduce harmful emissions from petrol and diesel engines. This system complies with Euro 1 and Euro 2 emission standards and includes specific catalysts tailored to various engine types used in the 1990-1994 Audi 100 series.

Catalytic converters are used on several Audi 100 C4 engines to meet emission standards, including :

• Diesel 2.5 TDI (engine code AAT) - 115 hp, produced until 07/1993
• Petrol S4 2.2 Turbo quattro (engine code AAN) - 230 hp, produced 1991-1994
• Other petrol engines including V6 2.8L and S4 4.2 V8 (280 hp, code ABH)
• 2.0 petrol engines (codes AAD, AAE, ABK)

These engines are equipped with catalytic converters designed to reduce toxic gas emissions, specific to each engine's requirements.

The catalytic converter, particularly the oxidation type used on petrol engines like the S4 2.2 Turbo, can reduce engine power slightly due to its emission control function. For example, power may drop from 120 hp in earlier models to 115 hp in some Audi 100 C4 variants because of the catalytic converter's presence.

However, this trade-off is necessary to meet legal emission standards and reduce environmental impact.

Prices for replacement catalytic converters for the Audi 100 C4 vary significantly depending on the model and supplier. Typical price ranges are :

• From around 125.64 € to 732 € for the sedan (4A2) models
• Specialised catalytic converters for 2.5 TDI or S4 2.2 Turbo engines may differ in cost due to their technical specifications.

It's important to ensure the catalytic converter matches the exact vehicle and engine specifications for proper fit and compliance.
