Audi A6 Avant S6.4 2 Quattro drivetrain

The Audi A6 Avant S6.4.2 Quattro is a car that blends practical utility with formidable performance. At the heart of its propulsion is the advanced Quattro system, distributing power from the potent 4.2-litre V8 engine to all four wheels. To transfer this power to the road effectively, the drivetrain must be in prime condition. Every component, from the gearbox out to the wheel hubs, operates under high loads, particularly during spirited driving or heavy acceleration. As driveline specialists, we understand the distinct demands placed on an Audi S model. We supply components that match original specifications to preserve your vehicle's handling and safety. Maintaining the drivetrain is vital to avoid costly secondary damage to differentials and the gearbox.

Our product range for the Audi A6 Avant S6.4.2 Quattro is curated to cover the most critical requirements. Whether you need to restore smooth power delivery or eliminate annoying vibrations, we supply the required parts. By choosing the right components from the start, you save both time and money while ensuring your Audi continues to deliver the performance it was engineered for. We are proud to be a Swedish driveline specialist providing both depth and breadth in this niche field.

How the Audi A6 Avant S6.4.2 Quattro drivetrain works

The drivetrain on an Audi A6 Avant S6.4.2 Quattro is an engineering masterpiece of permanent four-wheel drive. The system is built around a longitudinal engine connected to a gearbox with an integrated centre differential. From here, power is directed via a propeller shaft to the rear axle, while the front axle is driven directly from the front section of the gearbox. This setup provides the superb balance and traction for which the Quattro system is renowned. Each wheel is then linked to its respective differential via drive shafts fitted with both inner and outer CV joints.

The outer CV joints allow the wheels to turn whilst transmitting power, whereas the inner CV joints accommodate the vertical travel of the suspension. For a vehicle wearing the S6 badge, these components are dimensioned to handle the substantial torque generated by the V8 engine. In addition, the ABS rings play a central role in the vehicle's safety systems by providing wheel-speed data to both the ABS and traction control. Understanding this complex configuration is key to diagnosing where an issue has originated. Every link in the chain must work flawlessly to ensure the overall driving dynamics remain uncompromised.

Common faults and symptoms

Despite Audi's excellent build quality, the drivetrain remains subject to normal wear and tear. One of the most typical signs of a worn outer CV joint is a rhythmic clicking noise heard on full steering lock, such as when manoeuvring into a parking space. This is often caused by a split CV boot, which allows dirt to enter and grease to escape. If you instead experience chassis vibrations under acceleration, it may indicate that an inner constant velocity joint is failing. These vibrations can easily be mistaken for wheel imbalance, but they are typically linked to engine load.

Another symptom to watch for is vibration occurring at specific road speeds, which can suggest imbalance or wear in the propeller shaft or its centre bearing. If the ABS warning light illuminates or the system engages under normal braking, a cracked or corroded ABS ring is a very probable cause. By addressing these symptoms early, you can often prevent minor wear from turning into complete driveline failure requiring roadside recovery. Listening to your car is the first step in successful maintenance.
