ABS rings for Audi 90 2.3 E 20V Quattro

ABS rings for Audi 90 2.3 E 20V Quattro

Maintaining an Audi 90 2.3 E 20V Quattro requires precision and the correct components, especially when it comes to the car's advanced safety systems. The ABS ring, also known as an ABS reluctor ring, is a small yet vital part of the braking system on this four-wheel-drive classic. For a vehicle equipped with Quattro drive, synchronisation between the wheels is crucial, and a faulty signal from a damaged ring can disrupt more than just the anti-lock brakes. At CVJoint24, we specialise in these exact types of drivetrain components to ensure your car retains its original performance and safety.

Because the Audi 90 2.3 E 20V Quattro is a model with specific technical characteristics, never compromise on quality. An inferior ABS ring can cause recurring fault codes and unnecessary wear on other drivetrain parts. By choosing a vehicle-specific part from a specialist, you can rest assured that the dimensions match original specifications precisely, making installation straightforward and extending the service life of the entire suspension setup.

What does the ABS ring do on an Audi 90 2.3 E 20V Quattro?

The ABS ring is mounted on the CV joint and functions as part of an inductive measuring system. As the wheel rotates, the teeth of the ring pass an ABS sensor, generating an electrical pulse. The car's electronic control unit uses these pulses to calculate exactly how fast each wheel is turning. On an Audi 90 2.3 E 20V Quattro, this system is especially critical because the four-wheel-drive system relies on precise data to manage torque distribution optimally. If a ring is damaged, the ECU may detect that a wheel has locked up or is spinning, triggering the ABS when it is not needed.

Beyond basic braking, a properly functioning ABS ring allows the car's stability systems to work as intended. For Quattro owners, this ensures the legendary grip and roadholding remain intact. Without accurate signals from the ABS rings, the vehicle may feel jerky or unstable under braking on slippery surfaces. Investing in top-condition reluctor rings is therefore a vital safety measure, especially on a high-performance 20V model where tolerances are tight.

Common signs of wear

The most common issue with an ABS ring on older Audi models is corrosion. European winters with road salt and moisture cause rust to build up beneath the ring, creating outward pressure. This often causes the ring to crack. A cracked ring alters the spacing between the teeth, confusing the ABS sensor. A clear symptom is the ABS warning light illuminating on the dashboard, either permanently or intermittently at certain speeds. Another common telltale sign is the ABS pulsing through the brake pedal just before the car comes to a complete stop, even on dry tarmac with ample grip.

You may also notice the speedometer behaving erratically if it takes its reading from the same system, or that the four-wheel-drive system fails to engage as expected. A visual inspection will often reveal whether the ring has come loose, is missing teeth or has visible cracks. If you notice any of these symptoms on your Audi 90 2.3 E 20V Quattro, it is time to inspect the rings before the uneven surface damages the sensor, leading to more expensive repairs down the line.

How to choose the correct ABS ring

When buying a replacement ABS ring for your Audi 90 2.3 E 20V Quattro, three measurements are essential: the tooth count, the inner diameter and the width of the ring. Over the years, Audi used several configurations depending on the chassis number and drivetrain. For Quattro models, specifications frequently differ from front-wheel-drive variants. The most reliable way to find the right component is to filter by make, model and engine variant in our shop, ensuring you view only the parts compatible with your vehicle's exact specification.

If you are ever in doubt, we recommend counting the teeth on your old ring before ordering. An incorrect tooth count prevents the ABS system from calibrating correctly. At CVJoint24, we offer a fitment guarantee, taking full responsibility that the part fits your car when selected via our catalogue. This provides complete peace of mind when ordering spare parts for a specific model like the 2.3 E 20V Quattro, where precision is everything.

Related parts to inspect

Be sure to inspect these related parts for your vehicle when working on the ABS rings:

When a drivetrain component shows signs of wear, neighbouring parts often need checking as well. Reviewing these dedicated category pages for Audi 90 2.3 E 20V Quattro makes it easier to pinpoint whether an issue stems from the ABS ring itself or an adjacent section of the driveline.

This is especially important on models where vibrations, play and noises can transmit between multiple drivetrain components. A quick check of related categories reduces the risk of replacing one correct part while overlooking an adjacent component that contributes to the very same issue.
