Spare parts and drivetrain components for the Audi A6 1.8 T Quattro. Confirm fitment using your make, model and engine before ordering.
The Audi A6 1.8 T Quattro represents a unique balance between German engineering and practical four-wheel drive, where the drivetrain plays an entirely vital role in defining the car's character. Combining the turbocharged engine with the legendary Quattro system places specific demands on every single component in the powertrain. When maintaining an Audi A6 1.8 T Quattro, it is important to understand that the drivetrain is an integrated system where every part, from the smallest ABS ring to the robust propeller shaft, must operate in perfect harmony. Wear in one component can quickly lead to knock-on problems in other parts of the system, making the choice of the correct spare parts critical. At CVJoint24, we are specialists in these precise components and understand the technical nuances required to help your car maintain its original driving feel and road safety, whatever the weather conditions or road surface.
The drivetrain layout on an Audi A6 1.8 T Quattro is based on a longitudinal engine configuration, distinguishing it from many other cars in the same class. Power is delivered from the engine to a gearbox integrated with a central differential. This differential, often a Torsen unit, is the heart of the Quattro system, distributing power mechanically and continuously between the front and rear axles depending on where grip is strongest. From the gearbox, short drive shafts run out to the front wheels, fitted with both inner and outer CV joints to cope with suspension travel and steering angles. Running towards the rear, a propeller shaft transfers torque to the rear differential, which in turn delivers drive onward to the rear wheels via rear drive shafts. This entire system is optimised for maximum traction and stability, but it also entails more moving parts requiring inspection compared to a two-wheel-drive car. Every link in this chain is dimensioned to handle the torque output delivered by the 1.8 T engine, particularly under hard acceleration and cornering.
Identifying drivetrain faults on an Audi A6 1.8 T Quattro calls for close attention to distinct noises and vibrations. One of the most typical symptoms is a clicking or knocking sound from the front end on full steering lock, which almost invariably points to a worn outer constant velocity joint. If you instead experience vibrations through the entire body under acceleration, especially at higher speeds, it may indicate that the inner CV joints are starting to fail or that the prop shaft has developed an imbalance. For Quattro owners, it is also essential to watch for noises underneath the car, which can signify wear in the centre bearing on the propeller shaft. Another frequent issue is an illuminated ABS warning light or abnormal ABS activation at low speeds, which is commonly caused by a cracked or corroded ABS ring. Because the system is four-wheel drive, imbalance in one section of the drivetrain can easily propagate throughout the whole car, making it particularly crucial to address issues early before they inflict costly damage on the differentials or gearbox.

The most common signs are vibrations under acceleration or clicking noises when cornering. If the CV boot is split and grease has leaked out, the risk increases that the entire shaft will need replacing.
It requires removing the CV joint, which can be time-consuming. However, it is a very cost-effective repair compared to replacing the complete CV joint if only the ring is faulty.
Vibrations under acceleration are often caused by worn inner CV joints. On a Quattro model, it can also stem from an unbalanced propeller shaft or a worn centre bearing.
Yes, our kits for the Audi A6 1.8 T Quattro are supplied complete with the CV joint, CV boot, high-grade grease, clips and, where required, a new centre bolt.
The front and rear drive shafts differ in length and dimensions to suit the vehicle's chassis geometry and differentials. Always filter by your make, model and engine to ensure you get the correct shaft for the right position.
It means that once you select your make, model and engine variant and we confirm the part fits, we guarantee it can be fitted. If against all expectations it does not fit, we handle the return free of charge.
