ABS rings for Volvo S80 2.9
The Volvo S80 2.9 is renowned for its comfort, but just like any vehicle it requires regular maintenance of its safety systems. The ABS ring, also referred to as an ABS reluctor ring, is a vital component of the braking system that is often overlooked until a warning light appears on the dashboard. For the Volvo S80 2.9 in particular, it is essential to choose a ring that is precisely dimensioned to fit onto the CV joint. Because this model frequently covers high mileages on European roads, these components are exposed to harsh weather and road salt in winter. Over time, this leads to corrosion that can cause the ring to crack. At CVJoint24, you will find the right ABS ring to restore your anti-lock braking system and ensure your car passes its annual inspection with flying colours.
What does the ABS ring do on a Volvo S80 2.9?
On your Volvo S80 2.9, the ABS ring forms part of an inductive sensor system that monitors the rotational speed of each wheel. The ring is press-fitted onto the outer CV joint and rotates at the exact same speed as the road wheel. A magnetic sensor is positioned directly above the ring's teeth, reading the pulse signal as they pass. This data is transmitted to the car's ABS control module. If the control unit detects that one wheel is rotating slower than the others during braking, it modulates the brake pressure to prevent wheel lock-up. Without an intact ABS ring, the system cannot measure wheel speed correctly, disabling both the ABS and the traction and stability control systems (STC/DSTC) on your Volvo. It is a compact spare part, yet it plays a crucial role in vehicle safety.
Common signs of wear
The most obvious indication of a damaged ABS ring on your Volvo S80 2.9 is an illuminated ABS warning light. Often the issue starts intermittently, with the light triggering in wet conditions and turning off once dry. Another frequent symptom is unwanted ABS activation during normal, low-speed braking on completely dry tarmac. When this happens, you will feel the brake pedal pulse just before the car comes to a standstill. This is typically caused by the ABS ring cracking due to rust expansion underneath. The resulting crack widens the gap between two teeth, tricking the sensor into registering an abrupt change in wheel speed. In addition to warning lights, fault codes relating to wheel speed sensors may be stored, even though the reluctor ring itself is the root cause.
Choosing the right ABS ring
Selecting the correct ABS ring for your Volvo S80 2.9 requires precision. Different variations exist depending on the production year and chassis specifications. The critical details to verify are the tooth count and the inner diameter, as the ring is pressed directly onto the outer CV joint housing. A ring with the incorrect number of teeth will send inaccurate wheel speed signals, preventing the ABS system from functioning. Because the Volvo S80 2.9 has precise technical tolerances and material requirements, we recommend filtering your search on cvjoint24.com by your car's exact make, model and engine variant. This ensures you find the exact component matched to your car's technical configuration, saving you time and avoiding fitting issues.
Related parts to inspect
We recommend checking these exact 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 comparing these exact pages for the Volvo S80 2.9, you can easily determine whether the issue lies purely with the ABS ring or another related section of the driveline.
This is especially important on models where vibrations, play and unusual noises can transfer symptoms across several driveline components. Checking related categories helps ensure you replace the right part without overlooking an adjacent component that contributes to the problem.

Frequently asked questions about ABS rings for Volvo S80 2.9
How do I know if the ABS ring is broken on my Volvo S80 2.9?
The most common signs are an illuminated ABS warning light or a pulsating brake pedal when braking at low speed on dry tarmac. A visual inspection will often confirm if the ring is cracked or heavily corroded.
Can I replace just the ABS ring, or do I have to replace the complete CV joint?
You can certainly replace just the ABS ring if the CV joint itself is otherwise in good condition. However, if the joint makes noises or has play, it is better to replace the entire unit.
Why does the ABS ring crack on the Volvo S80?
It is usually caused by corrosion building up between the CV joint and the ring. As the rust expands, it creates pressure from beneath that eventually causes the steel ring to snap.
Will a cracked ABS ring cause an MOT or roadworthiness test failure?
Yes, if the ABS warning light is on or the system is not working properly, the car will fail its roadworthiness test as it is a safety risk.
How many teeth should an ABS ring have for a Volvo S80 2.9?
The number of teeth can vary depending on the model year. It is therefore important to select your car's exact make, model and engine to find the correct specification for your vehicle.
Do I need special tools to fit a new ABS reluctor ring?
No complex specialist tools are required, but the ring must be carefully pressed into place. It is essential to clean all rust off the mating surface on the CV joint thoroughly before fitting.
