ABS rings for Audi 90 2.3 E 20V

ABS rings for Audi 90 2.3 E 20V

The Audi 90 2.3 E 20V is a classic model celebrated for its distinctive five-cylinder engine and fine handling characteristics. To maintain this driving pleasure and safety, every component in the suspension and drivetrain must perform at its best. One of the most critical yet frequently overlooked parts is the ABS ring. A cracked or broken ABS ring can cause the anti-lock braking system to stop working correctly, impairing both safety and road feel. At CVJoint24, we specialise in supplying the right parts for your Audi 90 2.3 E 20V, helping you maintain the car's original performance for many years to come. Our focus is on offering parts that meet the exact technical requirements of this specific engine variant and its unique drivetrain.

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

The ABS ring, also known as an ABS reluctor ring or pulse wheel, is mounted on the CV joint and plays a central part in the car's active safety system. Its main task is to provide the ABS sensor with precise, real-time data regarding wheel rotational speed. By reading the evenly spaced teeth on the ring, the electronic control unit can detect whether a wheel is about to lock up under heavy braking. For an Audi 90 2.3 E 20V, this system is vital to preserving steering control and road stability. If the ring is damaged or dirty, incorrect signals are sent to the computer, which often causes the ABS system to trigger unnecessarily or cut out completely to avoid unsafe braking conditions. It is a mechanical part that enables advanced electronic safety.

Common signs of wear

The most common symptom of a faulty ABS ring is the ABS warning light illuminating on the dashboard without warning. You may also notice an unwanted pulsating sensation in the brake pedal during routine braking at low speeds, which is a clear sign that the ring has developed a crack disrupting the signal. Cracks often develop because corrosion forms underneath the ring on the outer CV joint seat, causing the metal to expand and snap. On an older classic like the Audi 90 2.3 E 20V, this is a frequent issue after decades on European roads exposed to road salt and moisture. In addition to cracking, heavy rust and road grime can clog the gaps between the teeth, preventing the sensor from obtaining a clear reading and triggering fault codes.

How to choose the correct ABS ring

Choosing the correct ABS ring for your Audi 90 2.3 E 20V requires close attention to technical specifications. It is essential to verify the tooth count on the ring and its inner diameter, as these measurements must be exact for the ring to press firmly into position and align with the sensor. Because variations exist depending on whether your car is front-wheel drive or equipped with the Quattro system, selecting your exact vehicle details is the safest way to find the right part. By choosing your car's make, model and engine, you can filter for parts guaranteed to fit your vehicle. We always recommend cleaning the mounting seat on the CV joint thoroughly before fitting the new ring to prevent unwanted tension and future cracking. Getting the right part straight away saves both time and hassle during repairs.

Related parts to inspect

Be sure to check these relevant 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 checking these exact pages for the Audi 90 2.3 E 20V, it becomes simpler to confirm whether the problem lies with the ABS ring or another related driveline component.

This is especially important on models where vibrations, play and unusual noises can transfer symptoms across several driveline components. Checking related categories reduces the risk of replacing one correct part while missing an adjacent component that contributes to the same issue.

• Audi 90 2.3 E 20V
• Outer CV joints for Audi 90 2.3 E 20V
• Inner CV joints for Audi 90 2.3 E 20V

While you are replacing the ABS ring, it is an ideal opportunity to inspect the rest of the drivetrain to prevent future issues. Because the ABS ring is fitted directly onto the outer CV joint, you should inspect the condition of your outer constant velocity joint thoroughly. If the joint exhibits wear, such as clicking noises on full steering lock, it may be more cost-effective to replace the complete CV joint, which often comes with a new ABS ring pre-installed. Do not forget to inspect your inner CV joints as well and confirm that the CV boots are intact and properly sealed. Here is a list of relevant parts for your car:

• Outer CV joint with ABS seat
• Inner CV joint and flanges
