ABS rings for Audi 100 Avant 2.2 CAT Quattro

ABS rings for Audi 100 Avant 2.2 CAT Quattro

Maintaining the braking system on a classic such as the Audi 100 Avant 2.2 CAT Quattro is vital for both safety and driving pleasure. The ABS ring, also known as a reluctor ring, is a small but fundamental part of the anti-lock braking system. For this specific model, combining the legendary five-cylinder engine with Quattro all-wheel drive, components must meet high standards and offer an exact fit. A defective ABS ring can quickly stop the vehicle's safety systems functioning as intended, which becomes especially noticeable on slippery road surfaces or during hard braking.

At CVJoint24, we understand the importance of preserving the original driving feel and function of your Audi. We therefore supply carefully selected ABS rings tailored specifically to the technical demands of the Audi 100 Avant 2.2 CAT Quattro, ensuring your car stays safe on the road for many kilometres to come. Selecting the right spare parts straight away also prevents unnecessary wear on other drivetrain components.

What does the ABS ring do on an Audi 100 Avant 2.2 CAT Quattro?

The ABS ring on your Audi 100 Avant 2.2 CAT Quattro works as a precision component within the electronic stability and braking systems. Mounted on the CV joint, it rotates at the same speed as the wheel. A magnetic sensor reads the teeth of the ring as it spins, generating an electrical signal transmitted to the ABS control unit. The control unit uses this data to calculate individual wheel speed in real time.

If a wheel is about to lock up under braking, the system detects this via the ABS ring signal and modulates the brake pressure immediately. For a car equipped with Quattro all-wheel drive, this data is particularly critical, as the system interacts closely with power distribution across the axles. Without an intact ABS ring, the vehicle loses its ability to regulate braking force individually at each wheel, drastically compromising roadholding and active safety in emergency situations.

Common signs of wear

There are several distinct signs that an ABS ring on your Audi 100 Avant 2.2 CAT Quattro is failing. The most frequent symptom is an illuminated ABS warning light on the instrument cluster, showing that the control module has detected an erratic signal or an interruption in the data stream. Another telltale symptom is the ABS kicking in inappropriately under completely normal braking on dry asphalt, typically just as the car comes to a final stop.

You may feel an abnormal pulsating or vibration through the brake pedal. This is frequently caused by a cracked ring resulting from corrosion beneath it; once the ring splits, the gap between two teeth widens, confusing the sensor into registering a locked wheel. If you hear a scraping noise from the wheel housing, a loose or distorted ring may be rubbing against the sensor itself, requiring prompt inspection to prevent damage to the ABS sensor.

How to choose the correct ABS ring

When selecting a replacement ABS ring for your Audi 100 Avant 2.2 CAT Quattro, paying close attention to technical specifications is essential. The primary differences between rings are the tooth count alongside the inner and outer diameters. Because the Audi 100 range features various configurations depending on engine options and whether the car has Quattro, dimensions can vary between model years.

The most dependable way to find the right part is to filter by your car's make, model and engine variant in our store. This identifies the components guaranteed to match your specific vehicle. Always verify that the ring's width matches your original part. Choosing a high-quality ring with appropriate anti-corrosion protection is also essential to withstand road salt and damp, which represent the main causes of split rings on older vehicles during European winters.

Related parts to inspect

Feel free to inspect these matching pages for your vehicle when replacing an ABS ring:

When a drivetrain part shows wear, neighbouring components on the car often require attention too. Comparing these exact pages for the Audi 100 Avant 2.2 CAT Quattro makes it straightforward to establish whether an issue stems solely from the ABS ring or another related transmission component.

This is especially pertinent on models where vibrations, play and unusual noises can transfer symptoms across several parts within the same driveline. A quick check across related categories lowers the risk of replacing one correct part while overlooking an adjacent component that contributes to the very same fault.
