Audi Q8 Catalytic Converter (2018-Today)

The Audi Q8 (type 4M) features a sophisticated exhaust system that includes ceramic catalytic converters positioned close to the engine. It is equipped with upstream and downstream lambda sensors to optimize emissions control. Engine configurations vary; for example, V6 TFSI engines use two ceramic catalytic converters near the engine, V6 TDI engines have a single ceramic catalytic converter, and 4-cylinder TFSI engines have a setup similar to TDI models.

The catalytic converter for the Audi Q8 55 TFSI (from 2015 onwards) complies with EURO 6 standards. Common specifications for aftermarket parts include:

• Weight: Approximately 7.4 kg
• Length: About 1130 mm
• Pollution standard: Euro 4 (D4) for some versions

For RS FSI Mild Hybrid quattro models, the catalytic converters are calibrated for up to 600 horsepower (441 kW).

Besides the main catalytic converter, the Audi Q8 integrates a complete emissions treatment system including:

• Exhaust gas recycling radiator
• Particulate filter sensor (DPF)
• Exhaust flap control unit (J883)
• Multiple silencers (central and side)
• Flexible connection pipes

This setup helps the vehicle meet stringent emissions and legal standards while ensuring engine performance.

To select the correct catalytic converter, it is important to know your vehicle's engine type, power output, emission standard, and VIN (Vehicle Identification Number). These details help ensure the catalytic converter fits properly and complies with emissions regulations. Our technical support team can confirm compatibility based on this information.

Prices for replacement catalytic converters vary by model and specification. Delivery times are typically between 1 to 4 days for in-stock items, with express options available. For current pricing and delivery details, please consult the product page or contact customer support. Note: prices exclude VAT and shipping fees may apply depending on the destination.

Catalytic converters contain precious metals like platinum, palladium, and rhodium, which are essential for converting harmful exhaust gases into less polluting emissions. These metals make catalytic converters highly valuable. Additionally, they are critical to the vehicle’s emissions control system and legal compliance.

• Convert toxic gases (CO, NOx, HC) into less harmful substances
• Help vehicles meet emissions regulations
• Contain rare and expensive metals

This value, combined with theft risks, makes protecting and replacing catalytic converters properly very important.

The average cost for an Audi Q8 catalytic converter replacement ranges widely depending on year, engine, and model specifics. Typically, expect prices starting around 700 to 900 € for standard Euro 6 compliant parts, with premium or specialized versions like RS Mild Hybrid calibrated converters priced higher. Installation and additional parts are extra.

To maintain performance and compliance, keep these points in mind:

• Always use unleaded petrol in petrol engines.
• Replace lambda sensors along with the catalytic converter after about 80,000 to 100,000 km.
• Check exhaust system tightness using copper connections if installing new connections before the catalytic converter.
• Follow manufacturer guidelines for installation and engine maintenance to avoid damage.
• Be aware of local laws regarding emissions and catalytic converter replacement to ensure legal compliance.

Proper maintenance and installation ensure the catalytic converter functions effectively and complies with emission laws.
