ABS rings for Audi 100 2.2 Turbo
The Audi 100 2.2 Turbo is a classic model renowned for its robust construction and powerful engine. To preserve the car's safety characteristics, it is essential that every component in the braking system and drivetrain functions flawlessly. One of the most critical, yet frequently overlooked, parts is the ABS ring. This small but vital component is mounted on the CV joint and plays a central role in the vehicle's anti-lock braking system. On a car like the Audi 100 2.2 Turbo, where performance and control are paramount, an intact ABS reluctor ring is a prerequisite for safe driving in all weather conditions.
At CVJoint24, we are specialists in these exact components. We understand that owners of classic Audi models demand high standards of precision and durability from their spare parts. Our range is carefully selected to meet the exact technical specifications required for the 2.2 Turbo variant, ensuring you receive a product that not only fits physically but also communicates correctly with the vehicle's electronic control unit. Choosing the right replacement part is the first step towards a successful repair and long-term reliability.
What does the ABS ring do on an Audi 100 2.2 Turbo?
The ABS ring, also known as an ABS reluctor ring or tone ring, operates as part of a magnetic sensor system. As the wheel rotates, the ring's teeth pass a stationary ABS sensor. This movement generates electrical pulses that are sent to the car's ABS control module. The control unit uses this data to calculate the exact rotational speed of each wheel. If the system detects that a wheel is about to lock up during braking, it instantly modulates brake pressure to maintain steering control and reduce stopping distances.
On an Audi 100 2.2 Turbo, this system is particularly crucial because the engine's torque and the car's mass require effective and dependable braking intervention. Without a functioning ABS ring, the control unit receives erratic signals or none at all, disabling the ABS function. This not only compromises safety during emergency braking but can also disrupt traction control if fitted. Understanding how the ring operates makes it clear why even minor tooth damage can have major consequences for handling and safety.
Common signs of wear
The most frequent problem with an ABS ring on older cars such as the Audi 100 is corrosion. Because the ring is exposed to road grime, moisture and winter road salt, rust inevitably develops over time. As corrosion builds up underneath the ring, it exerts outward pressure that eventually causes the hardened steel ring to crack. A cracked ring alters the spacing between the teeth, confusing the ABS sensor and sending incorrect data to the car's ECU. This typically triggers the ABS warning light on the dashboard.
Another common symptom is false ABS activation during gentle, low-speed braking just before coming to a complete stop. You may feel an unexpected pulsation or vibration through the brake pedal. This happens because the sensor loses its signal over the crack and mistakenly assumes the wheel has locked up. If you notice these symptoms, it is time to inspect your ABS rings. Ignoring the issue can cause unnecessary wear on other brake components and compromise safety in critical driving situations.
How to choose the correct ABS ring
Selecting the correct ABS ring for an Audi 100 2.2 Turbo requires precision. Variations exist depending on the model year and whether the vehicle is front-wheel drive or equipped with the Quattro all-wheel-drive system. The most important measurements are the tooth count and the inner diameter. An ABS ring with the wrong number of teeth will transmit incorrect wheel-speed signals, leaving the ABS system inoperative despite fitting a brand-new part. For the 2.2 Turbo variant, it is essential to verify that the part is engineered for this high-performance drivetrain.
The simplest and most reliable way to find the correct component is to select your car by make, model and engine variant in our catalogue. We also advise comparing the old ring with the new replacement whenever possible, or measuring the seating diameter on the constant velocity joint where the ring is pressed on. With our fitment guarantee, you can be confident that you will get the right part the first time, saving both time and labour costs in the garage.
Related parts to check
Please feel free to check these specific 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 attention as well. By checking these matching pages for the Audi 100 2.2 Turbo, you can more easily determine whether an issue lies with the ABS ring itself or another adjacent drivetrain component.
This is especially important on models where vibrations, play and unwanted noises can transfer symptoms across interconnected driveline assemblies. Checking related categories reduces the risk of replacing one component while overlooking another worn part that produces identical symptoms.
By taking a proactive approach and replacing damaged CV boots or worn CV joints alongside the ABS ring, you prevent future breakdowns and save on repeat workshop labour. A well-maintained drivetrain is central to your Audi's performance.

Frequently asked questions about ABS rings for Audi 100 2.2 Turbo
How do I know if the ABS ring on my Audi 100 2.2 Turbo is broken?
The most common signs are an illuminated ABS warning light, or a pulsing sensation in the brake pedal at low speeds just before coming to a complete stop. A visual inspection will often reveal cracks caused by rust.
Do I have to replace the entire CV joint if only the ABS ring is cracked?
No, on the Audi 100 2.2 Turbo you can often simply replace the ABS ring on its own. This is a much more cost-effective solution than replacing the entire CV joint, provided the joint itself is otherwise in good condition.
Why do ABS rings crack on older Audi models?
This is primarily caused by corrosion. Rust builds up between the CV joint and the ring, creating outwards pressure from underneath. Because the ring is made of hardened steel, it is brittle and eventually cracks when this pressure becomes too high.
How many teeth should the ABS ring have on an Audi 100 2.2 Turbo?
The number of teeth can vary depending on the exact specification and model year. It is therefore very important to select your car's make, model and engine to find the exact replacement part for your vehicle.
Can I drive my Audi 100 if the ABS ring is broken?
The car can still be driven, but the ABS system will not function correctly or may be deactivated entirely. This means an increased risk of wheel lock-up under heavy braking, so we recommend repairing the fault as soon as possible.
Is it difficult to replace an ABS ring yourself?
It requires disconnecting the drive shaft from the wheel hub. Once the joint is exposed, the old ring can be tapped off and the new one pressed or heat-fitted into place. This job requires some mechanical experience and the right tools.
