ABS rings for Audi A4 2.0 TDI Quattro
The Audi A4 2.0 TDI Quattro is a car renowned for its stability and advanced four-wheel-drive system. For this system to perform at its best, precise data from every wheel is essential, made possible by a functioning ABS ring. Also known as an ABS reluctor ring, this component is mounted on the CV joint and forms a critical part of the vehicle's safety system. Because the Quattro system distributes power across all four wheels, it is especially important that the sensors receive accurate signals to prevent inappropriate intervention from the stability control or anti-lock brakes. We supply carefully selected parts that satisfy the demanding requirements of your Audi A4. By choosing a part engineered specifically for the 2.0 TDI Quattro drivetrain, you ensure that the vehicle's control systems communicate seamlessly.
What does the ABS ring do on an Audi A4 2.0 TDI Quattro?
The primary role of the ABS ring is to serve as a reference point for the ABS sensor. As the wheel turns, the teeth of the ring pass the sensor, generating an electrical pulse. The vehicle's electronic control unit relies on these pulses to calculate the exact speed of each wheel in real time. On an Audi A4 2.0 TDI Quattro, this information is vital not only for the brakes, but also for how the all-wheel-drive system manages torque transfer between the front and rear axles. If a ring becomes damaged, cracked or heavily corroded, the control unit may register that a wheel is locking up or losing traction, causing the system to intervene incorrectly. It is a compact yet technically crucial component within the entire drivetrain ecosystem that requires precision in both manufacture and installation.
Common symptoms of wear
The most frequent sign of a faulty ABS ring is the ABS warning light illuminating on the dashboard, often accompanied by alerts for the ESP or traction control system. This typically happens when the reluctor ring cracks due to rust forming underneath, altering the spacing between the teeth or causing the ring to slip on the CV joint. Another clear indicator is an ABS system that pulses or judders through the brake pedal at low speeds, even under normal braking on dry tarmac. Audi drivers may also notice erratic all-wheel-drive behaviour if the wheel speed signals become unreliable. Because the ring is exposed to the elements, road grime and salt, rust expansion is by far the most common reason for replacement on cars driven through harsh European winters.
How to choose the correct ABS ring
Selecting the right ABS ring for an Audi A4 2.0 TDI Quattro demands precision, as tooth counts, inner diameters and widths can vary depending on the exact model year and the original CV joints fitted at the factory. To ensure you order the right part the first time and avoid unnecessary delays, simply select your car's make, model and engine in our vehicle selector. This will display the components that are technically compatible with your specific car and its Quattro drivetrain. We focus on supplying parts engineered for a perfect fit so your repair goes smoothly without awkward modifications. Counting the teeth on your old ring before ordering is also a sensible check to guarantee complete compatibility with the original equipment.
Related parts to check
It is also worth checking these relevant category pages for the same vehicle when working on the ABS ring:
When one drivetrain component shows signs of wear, neighbouring parts on the vehicle often warrant inspection as well. By checking these related pages for the Audi A4 2.0 TDI Quattro, it becomes much easier to determine whether the issue lies solely with the ABS ring or another connected component in the power transmission system.
This is particularly true for models where vibrations, play and unwanted noises can transfer symptoms across several parts in the same drivetrain. A quick look over related categories helps ensure you do not replace one worn part whilst overlooking adjacent components contributing to the same problem.

Frequently asked questions about ABS rings for Audi A4 2.0 TDI Quattro
Can I replace just the ABS ring, or do I need to replace the entire CV joint?
In many cases you can replace just the ABS ring if the CV joint itself is otherwise in good condition. However, it requires the mating surface to be thoroughly cleaned of all rust before fitting the new ring.
Why does the ABS ring crack on my Audi A4?
The most common cause is corrosion forming on the CV joint beneath the ring. As the rust expands, it creates immense outward pressure, which eventually causes the metal ring to snap.
How do I know how many teeth my ABS ring should have?
The most reliable method is to select your vehicle's exact make, model and engine variant on our website. To be absolutely certain, you can also count the teeth on the old ring before ordering.
Does a cracked ABS ring affect the car's four-wheel-drive system?
Yes, on a Quattro model, incorrect wheel speed signals can disrupt the control unit's calculations for torque distribution, which can lead to reduced traction and inconsistent drive.
Is it difficult to fit a new ABS ring yourself?
It requires removing the CV joint from the wheel hub. The new ring usually needs to be heated gently so that it expands, allowing it to shrink-fit securely onto the cleaned surface as it cools.
What happens if I keep driving with a cracked ABS ring?
Safety systems such as ABS and ESP will most likely be deactivated, meaning the wheels may lock up under hard braking and the electronic stability control will not function correctly.
