ABS rings for Audi 80 S2 Quattro

ABS rings for Audi 80 S2 Quattro

The Audi 80 S2 Quattro represents an era of engineering brilliance from Ingolstadt, and preserving its exceptional handling requires components that truly measure up. The ABS ring, also known as a reluctor ring or sensor ring, plays a vital role in the car's active safety systems. On a powerful four-wheel-drive vehicle like the S2 Quattro, a faultlessly operating ABS system is fundamental for managing torque distribution and stability under hard braking. At CVJoint24, we specialise in these critical components, and our range of ABS rings is carefully chosen to fit your Audi 80 S2 Quattro perfectly. Choosing the right quality ensures that your car's original safety performance is preserved for many years to come.

What does an ABS ring do on the Audi 80 S2 Quattro?

The ABS ring on an Audi 80 S2 Quattro functions as the mechanical counterpart to the ABS sensor. It is typically pressed onto the outer CV joint and consists of a series of teeth that pass the sensor as the wheel rotates. This movement generates an electrical signal whose frequency corresponds directly to wheel speed. The vehicle's control unit (ECU) analyses these signals from all four wheels hundreds of times per second. If the system detects that one wheel is rotating significantly slower than the others under braking, indicating an imminent lock-up, it regulates the brake pressure to that specific wheel. For a Quattro model, this precision is especially critical because the system works in tandem with differentials and traction control to maximise grip.

Common signs of wear

Over time, the ABS ring on your Audi 80 S2 Quattro is exposed to extreme conditions such as road salt, moisture and temperature swings. The most common form of wear is corrosion working its way beneath the ring, building outward pressure that eventually causes the hardened steel ring to crack. A cracked ring alters the spacing between the teeth, sending an erratic signal to the sensor. Common symptoms include an ABS warning light that illuminates permanently or intermittently. Another clear sign is feeling the ABS judder through the brake pedal just before the vehicle comes to a complete halt, even on dry tarmac with plenty of grip. A visual inspection will often reveal visible cracks or a ring that has worked loose on the CV joint.

Choosing the correct ABS ring

When it is time to replace the ABS ring on your Audi 80 S2 Quattro, it is crucial not to look purely at price, but at technical specifications. The tooth count on the ring must be completely accurate to match the car's management system; a single tooth too many or too few renders the system inoperable. Furthermore, the inner diameter is critical so that the ring can be pressed onto the constant velocity joint with the correct interference fit. We strongly recommend selecting your vehicle by make, model and engine to find the right part. Before fitting, thoroughly clean rust and dirt from the mounting surface of the constant velocity joint so that the new ring sits square and secure, avoiding future issues.

Related parts to inspect

Feel free to check these specific pages for the same vehicle when working on the ABS ring:

When a driveline component shows signs of wear, neighbouring components on the same car often need checking as well. Comparing these exact pages for the Audi 80 S2 Quattro makes it easier to tell whether an issue stems from the ABS ring itself or from another nearby part of the drivetrain.

This is particularly relevant on models where vibrations, play and unwanted noises can shift symptoms across several parts in the same driveline. A quick check of related categories minimises the risk of replacing the right type of part while overlooking an adjacent component that affects the same fault.

• Inner CV joints for Audi 80 S2 Quattro
• Propeller shaft Audi 80 S2 Quattro

Replacing an ABS ring provides an ideal opportunity to inspect the rest of the drivetrain on your Audi 80 S2 Quattro. Because you often need to dismantle parts of the suspension to access the ring, you should inspect the condition of your Outer CV joints for Audi 80 S2 Quattro. If the boot is split, it should also be replaced to prevent dirt from damaging the joint. Do not forget to inspect your Inner CV joints for Audi 80 S2 Quattro and the car's propeller shaft for vibrations or play. Maintaining the entire driveline chain on an Audi 80 S2 Quattro ensures that its legendary all-wheel-drive system continues to deliver power to the road effectively and safely.
