ABS rings for Audi 100 1.8 CAT
The Audi 100 1.8 CAT is an iconic classic that deserves top-quality spare parts to maintain its roadworthiness and safety. The ABS ring, also known as an ABS reluctor ring, is a vital component in your vehicle’s braking system. At CVJoint24, we understand the importance of precise fitment, especially for older classics where specifications can vary across production runs. Our selection of ABS rings for this specific Audi model is carefully chosen to meet or exceed original equipment standards. Replacing a damaged or cracked ring restores your car's ability to regulate braking pressure under heavy deceleration, preventing wheel lockup and maintaining steering control in emergencies. We combine technical expertise with specialised stock so you can order replacement car parts for your classic Audi with complete confidence.
What does the ABS ring do on an Audi 100 1.8 CAT?
The ABS ring on an Audi 100 1.8 CAT forms an essential part of the electronic anti-lock braking system. It is a toothed metal ring mounted on the outer CV joint that spins at the exact speed of the wheel. An ABS wheel speed sensor reads the teeth as they pass, generating a pulsed electrical signal transmitted directly to the ABS control module. The control unit relies on this data to monitor wheel speed in real time. If a wheel threatens to lock under braking, the system detects the anomaly via the signal from the ABS ring and instantly modulates hydraulic brake pressure to that corner. For a classic saloon like the Audi 100 1.8 CAT, this operation is fundamental for stability on slick European roads, and an undamaged ring is essential for the entire safety system to function correctly.
Common signs of wear and failure
Several distinct symptoms indicate that the ABS ring on your Audi 100 1.8 CAT is cracked, corroded, or missing teeth. The most frequent sign is an illuminated ABS warning light on your dashboard, signalling that the control unit is no longer receiving a coherent wheel speed reading. Another typical symptom is unwanted ABS pedal kickback or vibration during gentle, low-speed braking just before coming to a complete stop. This happens when a fractured ring creates an irregular tooth gap, tricking the sensor into registering a wheel lockup while the car is still rolling smoothly. Given the age of the Audi 100, corrosion is the primary culprit: rust builds up beneath the ring on the constant velocity joint, expanding outwards until the metal ring cracks under tension.
Choosing the right ABS ring
Selecting the correct ABS ring for an Audi 100 1.8 CAT requires paying close attention to technical specifications. Variations exist depending on production dates and equipment specifications on the 1.8 CAT variant. The most crucial steps are counting the number of teeth on your existing ring and checking its inner diameter, as these dimensions must match exactly for the ABS sensor to deliver accurate data to the ECU. At CVJoint24, we make ordering the right spare parts simple: select your car’s make, model, and engine variant to view components matched to your specific vehicle. We stock the correct parts for this model so you can avoid guesswork. An accurately fitted ring with the correct dimensions is your guarantee that the anti-lock braking system will perform just as the manufacturer intended.
Related driveline components to inspect
You can also check these matching category pages for the same vehicle when working on the ABS ring:
Whenever one drivetrain part begins to show wear, neighbouring components often require inspection as well. Comparing these dedicated pages for the Audi 100 1.8 CAT makes it straightforward to establish whether an issue stems solely from the ABS ring or another related driveline assembly.
This is particularly valuable on older vehicles where vibrations, play, and strange noises can easily travel between driveline components. Checking related categories helps ensure that you do not replace one part while missing a worn adjacent item that causes identical symptoms.
Servicing connected components at the same time saves both workshop hours and expense, as the suspension and wheel hub assembly will already be dismantled for access.

Frequently asked questions about ABS rings for Audi 100 1.8 CAT
How do I know if the ABS ring fits my Audi 100 1.8 CAT?
Select your car's make, model and engine to ensure an exact fit for your specific vehicle variant.
Can I replace just the ABS ring, or do I need to replace the entire CV joint?
On the Audi 100 1.8 CAT, it is often possible to replace just the ring if the CV joint itself is otherwise in good condition and undamaged.
Why do ABS rings crack on older Audi models?
The most common cause is rust developing on the CV joint underneath the ring, which builds outward pressure until the metal finally fractures.
Does a cracked ABS ring affect the roadworthiness inspection?
Yes, if the ABS warning light is on or the system is malfunctioning, your car will not pass its roadworthiness test (such as the MOT).
What tools are needed to replace the ABS reluctor ring?
You will need standard hand tools to detach the drive shaft, as well as a heat source to make sliding the new ring onto the CV joint easier.
Is the ABS ring the same across all Audi 100 models?
No, it can vary depending on the engine variant and model year, so always check the tooth count and diameter carefully before ordering.
