Purpose and compatibility

The presented gearbox belongs to the Manual gearboxes category and has been designed to work with the 4.2 FSI petrol engine with the CAUA code in the Audi A5 8T model with Quattro drive. The manual design provides direct control over gear ratios, which is particularly valued in powerful naturally aspirated units and during dynamic driving.

It is always worth confirming the selection of this gearbox for a specific vehicle using the VIN and part numbers to ensure full compatibility with the factory drivetrain configuration.

Technical and operational characteristics

The manual version of the gearbox has been developed to handle the high torque of the 4.2 FSI unit in combination with all-wheel drive. The use of a classic, mechanical gear shifting system allows for:

• precise power delivery to the wheels across the entire rev range,
• better control over the car in sporty driving conditions,
• effective use of the petrol engine's characteristics at high RPMs.

For the user, this means predictable drivetrain behavior, consistent with Audi's factory specifications for the 4.2 FSI Quattro version.

Application in the Audi drivetrain

The manual gearbox in this model plays a key role in transferring power to all wheels, working in conjunction with the Quattro system and other drivetrain components. A properly selected transmission:

• maintains the correct gear ratios for the weight and power of the Audi A5 8T,
• supports vehicle stability at higher speeds,
• ensures consistent operation with traction control and electronic stability programs.

Thanks to this, replacing a damaged or worn gearbox with an original component from the same design group allows you to maintain the factory driving characteristics and character of the car.

Condition, origin, and part selection

The offered gearbox comes from the Audi brand and is a used component, which in practice means a favorable cost-to-functionality ratio while maintaining the manufacturer's original specifications. Before installation, standard workshop verification and replacement of consumables in accordance with service procedures are recommended.

To select the correct unit for your car, it is worth using the manufacturer's markings, replacement numbers, and vehicle data.
