ABS rings for Audi 100 1.8
The Audi 100 1.8 is an iconic model representing an era of German engineering where durability and comfort were at the forefront. To maintain these qualities, especially concerning safety, it is essential that every component in the braking system functions flawlessly. The ABS ring is one of those parts often overlooked until the warning light comes on, but its role in vehicle stability under braking cannot be overstated. On an Audi 100 with the 1.8-litre engine, the drivetrain is robustly engineered, yet the ravages of time and harsh European winter roads with road salt take their toll on the metal over time. Corrosion is by far the most common reason an ABS ring cracks or loses its magnetic properties. By choosing a model-matched replacement part from us, you ensure your car remains safe and avoids unnecessary inspection failures. We specialise in these precise car parts to offer owners of classic Audi models the best possible conditions for a successful replacement.
What does an ABS ring do on an Audi 100 1.8?
The technical function of an ABS ring on an Audi 100 1.8 is both straightforward and ingenious in design. The ring acts as an integral part of an inductive measuring system monitoring wheel rotation. As the wheel turns, the teeth of the ring pass in front of a fixed ABS sensor. Each passing tooth generates an electrical pulse in the sensor, and the frequency of these pulses tells the car's control unit precisely how fast each individual wheel is turning relative to the others. If you brake hard and the control unit detects that pulses from one wheel suddenly drop drastically or stop completely—indicating the wheel is about to lock up—the system immediately intervenes and releases brake pressure several times per second. This ensures you maintain steering control even during emergency braking on slippery surfaces. Without an intact ABS ring delivering a clean, consistent signal, this system cannot function correctly, causing the vehicle to revert to conventional braking without its vital anti-lock safety function.
Common signs of wear
Identifying a failing ABS ring on your Audi 100 1.8 requires paying close attention to how the vehicle behaves whilst driving. The most obvious indicator is an ABS warning lamp that stays permanently illuminated or comes on intermittently at certain speeds. Another very common symptom is a pulsating sensation in the brake pedal during completely normal braking at low speeds, just before the car comes to a complete standstill, even on dry tarmac with plenty of grip. This is often caused by a crack in the ring that creates too wide a gap between two teeth, which the control unit misinterprets as a locked wheel. During visual inspection, you can frequently see that the ring has expanded due to rust developing between the CV joint and the ring, which ultimately forces the hardened metal of the ring to snap. If the ring is loose or has visible damage, it is high time for a replacement before the system fails entirely or causes unwelcome interventions during everyday driving.
How to choose the correct ABS ring
When it is time to order a new ABS ring for your Audi 100 1.8, it is important to remember that specifications may vary depending on the vehicle's exact build. The tooth count is the most critical factor; a ring with the incorrect number of teeth will send inaccurate speed information to the control unit, preventing the ABS system from calibrating correctly. Alongside tooth count, you must also consider the inner diameter, outer diameter and width of the ring so that it seats securely on the CV joint without any play. On the Audi 100 range, these dimensions can differ depending on whether the car is front-wheel drive or four-wheel drive, as well as the specific model year. To make the process as straightforward as possible, simply select your car's make, model and engine variant on our website. We then match your vehicle's details against our stock to display the exact compatible ABS reluctor rings. This eliminates guesswork and ensures you receive a part that fits straight away during installation, saving you both time and hassle.
Related parts to inspect
Be sure to check these related pages for the same vehicle when working on the ABS ring:
When a drivetrain component shows signs of wear, neighbouring parts on the same car often require inspection as well. By comparing these exact pages for the Audi 100 1.8, it becomes easier to determine whether the issue lies specifically with the ABS ring or another adjacent section of the drivetrain.
This is particularly relevant on models where vibrations, play and unusual noises can shift symptoms between multiple components in the driveline. A quick check of related categories reduces the risk of replacing the right type of component while missing a neighbouring part that affects the same fault.

Frequently asked questions about ABS rings for Audi 100 1.8
What are the most common signs of a broken ABS ring on an Audi 100 1.8?
The most common symptoms are the ABS warning light illuminating on the dashboard or the brake pedal pulsating when braking at low speeds on dry tarmac.
Can I replace just the ABS ring, or do I need to replace the entire CV joint?
In many cases, you can simply replace the ABS ring on its own, provided the CV joint itself is in good condition with no play or unusual noises.
Why do ABS rings crack on older cars like the Audi 100?
This is usually caused by rust developing on the CV joint beneath the ring. As corrosion expands, it exerts immense outward pressure that eventually causes the hardened metal ring to crack.
How do I know how many teeth my ABS ring should have?
The most reliable method is to count the teeth on your old ring or select your Audi 100 1.8 by make, model and engine in our shop to find the correct specification.
Will a faulty ABS ring cause an MOT or roadworthiness test failure?
Yes, if the ABS warning light is on or the system does not operate correctly, the car will fail its roadworthiness inspection because it is classified as a safety defect.
Is it difficult to fit a new ABS ring yourself?
It requires removing the CV joint from the wheel hub. The new ring is then pressed or heat-fitted into position. It requires some mechanical experience and the correct tools to achieve a proper result.
