ABS rings for Audi A4 1.8 T
The Audi A4 1.8 T is renowned for its fine balance between performance and comfort, but like any vehicle, its safety systems require regular maintenance. The ABS ring is a central component of this setup, responsible for supplying the car's control unit with precise wheel-speed data. Here at CVJoint24, you will find a carefully curated range of ABS rings specifically tailored to the Audi A4 1.8 T. As a Swedish driveline specialist, we ensure our products match or exceed original equipment standards. Choosing the right spare parts is vital to maintain your car's handling and safety systems, especially in demanding European road conditions where road salt and moisture take a heavy toll on metal components.
What does the ABS ring do on an Audi A4 1.8 T?
The ABS ring on your Audi A4 1.8 T plays a decisive role in the car's active safety. It acts as a reluctor ring for the ABS wheel speed sensor. As the wheel rotates, the ring's teeth and windows generate an electrical pulse signal in the sensor, sent directly to the ABS control module. This information is used not only for anti-lock braking, but also for traction control (ASR) and electronic stability control (ESP). If the ring is damaged, the system can no longer tell whether a wheel has locked or lost grip, causing the safety systems to disengage or intervene incorrectly. On a spirited car like the Audi A4 1.8 T, having these systems working flawlessly is essential for delivering power safely to the road.
Common signs of wear
There are several clear warning signs indicating that the ABS ring on your Audi A4 1.8 T needs replacing. The most obvious is an illuminated ABS warning light on your dashboard, either permanently or intermittently. Another classic symptom is a pulsating sensation through the brake pedal during gentle braking on dry tarmac, just before coming to a complete stop. This happens because a cracked ring creates an abnormal gap that the control unit interprets as wheel lock-up. A visual inspection often reveals that corrosion forming between the CV joint and the ring has forced it to expand, eventually causing it to snap. Ignoring these warning signs can increase braking distances and lead to an MOT test failure.
Choosing the right ABS ring
When purchasing a replacement ABS ring for your Audi A4 1.8 T, it is important to check the technical specifications carefully. Over the production years, Audi used different CV joints and consequently different ABS reluctor rings, depending on whether the car is front-wheel drive or Quattro, as well as the specific gearbox fitted. The most critical dimensions to check are the tooth count and the internal diameter. An ABS ring with the wrong number of teeth will send incorrect speed pulses, rendering the system inoperative. To make selection straightforward, simply choose your car's make, model and engine variant in our shop. This guarantees an exact fit for your specific Audi model and saves valuable time during installation.
Related parts to check
Feel free to check these related pages for the same vehicle when working on an ABS ring:
When one driveline component shows signs of wear, neighbouring parts on the same car often require attention as well. Comparing these exact pages for the Audi A4 1.8 T makes it much easier to determine whether an issue lies with the ABS ring itself or an adjacent drivetrain component.
This is especially important on models where vibrations, play and unusual noises can transfer between several parts in the same driveline. A quick check of related categories reduces the risk of replacing the right part type while missing a neighbouring component that causes the same symptom.

Frequently asked questions about ABS rings for Audi A4 1.8 T
How do I know if the ABS ring fits my Audi A4 1.8 T?
The most reliable way is to select your car's exact make, model and engine variant in our shop. We then match your car's technical specifications to the correct ABS ring to ensure a precise fit.
Can I replace just the ABS ring, or must the entire CV joint be replaced?
It is often perfectly fine to replace only the ABS ring if the CV joint is otherwise in good condition. However, if the constant velocity joint is heavily rusted or worn, it may be more economical to replace the entire assembly.
Why does the ABS ring crack on an Audi A4?
The most common cause is corrosion forming on the CV joint beneath the ring. Rust expands and exerts pressure from the inside, which eventually forces the metal reluctor ring to crack.
What are the symptoms of a broken ABS reluctor ring on an Audi?
Common symptoms include an illuminated ABS warning light, a pulsating brake pedal at low speeds, or erratic behaviour from the traction control system.
Is it difficult to fit a new ABS ring?
It requires removing the CV joint and thoroughly cleaning all rust from the seating surface. The new ring usually needs to be gently heated so it can be pressed correctly into place.
Will a cracked ABS ring affect the MOT inspection?
Yes, if the ABS light is on or the system does not function correctly, your Audi A4 1.8 T will fail its roadworthiness inspection for safety reasons.
