ABS rings for Volvo S40 1.9 T4
Finding the right ABS ring for your Volvo S40 1.9 T4 is vital for your car's safety and performance. This specific model, powered by the punchy 1.9 T4 engine, places high demands on every component in the drivetrain working in complete harmony. The ABS ring, also known as an ABS reluctor ring, is a precision component that must feature the exact dimensions and tooth count to communicate properly with the vehicle's control unit. At CVJoint24, you will find carefully selected parts tested to satisfy the technical requirements of your Volvo S40. Choosing a model-specific component minimises the risk of fault codes and future braking system issues.
We understand how essential it is that your car stays safe on the road, which is why we only supply car parts built to the highest standards for this classic saloon. With the correct ABS ring, you restore your car's original safety performance and ensure that the electronic driver aids can react instantly whenever necessary. Our catalogue covers the precise demands of maintaining older performance vehicles, where precision is key to a lasting repair.
What does an ABS ring do on a Volvo S40 1.9 T4?
The ABS ring on a Volvo S40 1.9 T4 plays an integral role in the car's active safety system. Mounted on the drive shaft, typically on the outer CV joint, it rotates at the exact speed of the wheel. A magnetic wheel speed sensor reads the teeth of the ring as it spins, generating an electrical signal relayed to the ABS control module. This data is used to detect whether a wheel is locking under braking or breaking traction during acceleration. In a car delivering the performance of the 1.9 T4 engine, it is crucial that the traction control and ABS functions operate flawlessly.
Without an intact ABS ring, the system cannot calculate wheel speeds accurately, leading to vital safety functions shutting down or acting erratically. This can cause increased stopping distances or vehicle instability under heavy braking. The ring serves as the physical link between mechanical wheel rotation and electronic monitoring, making it one of the most critical small parts in your driveline and brake system. Keeping these components in top condition is essential for retaining your car's dynamic road manners.
Common signs of wear
There are several typical symptoms indicating that the ABS ring on your Volvo S40 1.9 T4 has cracked or worn out. The most frequent indicator is an illuminated ABS warning light on your dashboard, often accompanied by a general brake system warning message. Another unmistakable sign is unwanted ABS actuation, where you feel the brake pedal judder or pulse under gentle braking at low speeds on dry tarmac. This usually happens when corrosion builds up beneath the ring, causing it to crack and widening the gap between two teeth at the fracture point.
The sensor misinterprets this altered gap as a stationary wheel while the car is still moving, triggering the ABS pump needlessly. If your Volvo behaves oddly when slowing down or throws a warning light, it is time to inspect your ABS reluctor rings. Cracks or missing teeth are often clearly visible simply by removing the wheel and looking behind the brake disc. Ignoring these symptoms can cause the expanding, cracked ring to strike and mechanically damage the ABS sensor, resulting in extra repair costs and compromised driving safety.
How to choose the correct ABS ring
When selecting a replacement ABS ring, never rely purely on visual similarity. For the Volvo S40 1.9 T4, specific technical specifications must be matched exactly. These primarily include the ring's tooth count, its inner diameter designed to press onto the CV joint, and its width. An ABS ring with the wrong number of teeth will send inaccurate wheel speed readings, preventing the ABS system from calibrating correctly. We strongly advise using our vehicle selector by choosing your car's make, model and engine to find the right match straight away.
This guarantees that you receive a part engineered for your specific model year and engine variant. As driveline specialists, we know the subtle differences between individual configurations, saving you time and hassle during installation. Investing in the right part from the outset is the most cost-effective way to service your braking system. Our products are made from materials offering excellent corrosion resistance to withstand harsh European winters, where road salt frequently accelerates rust formation.
Related parts to inspect
Feel free to check these related pages for the same vehicle while replacing your ABS ring:
When a driveline component shows signs of wear, adjacent parts on the vehicle often warrant an inspection as well. Comparing these exact pages for your Volvo S40 1.9 T4 makes it easier to determine whether an issue lies solely with the ABS ring or another related part of the drivetrain.
This is especially true on models where vibrations, play or noises can make symptoms appear across multiple components in the driveline. Reviewing related categories helps ensure that you do not replace one correct item while overlooking a neighbouring part that affects the very same issue.
By carrying out a thorough check of the entire drivetrain, you avoid having to strip down the suspension repeatedly over a short period. Fitting a fresh CV boot while replacing the ABS ring is inexpensive insurance against future constant velocity joint failure.

Frequently asked questions about ABS rings for Volvo S40 1.9 T4
Does the same ABS ring fit all Volvo S40 models?
No, the ABS ring can vary depending on the engine variant and model year. For the 1.9 T4, it is important to check the tooth count and diameter. Always select your vehicle's make, model and engine to find the correct part.
Why does the ABS ring crack on my Volvo S40?
The most common cause is corrosion forming on the CV joint beneath the ring. As the rust expands, it exerts outward pressure from within that eventually causes the hardened steel ring to split.
Can I drive my Volvo S40 1.9 T4 with a broken ABS ring?
It is not recommended. A broken ring can cause the ABS system to behave unpredictably or shut down completely, impairing vehicle safety during heavy braking.
Do I have to replace the entire drive shaft if the ABS ring is broken?
No, in most cases you can simply replace the ABS ring itself. This is a much more cost-effective solution than replacing the entire drive shaft or CV joint.
How do I know whether the ABS ring or the sensor is faulty?
If the ABS pulses at low speeds, the cause is usually a cracked ring. If the ABS warning light stays on continuously without pedal pulsation, the sensor may be faulty. A visual inspection of the reluctor ring usually provides the answer.
Are fitting instructions included when I buy an ABS ring?
We provide technical specifications for the part. Replacing the ring involves pressing or gently heating the new ring into place, which must be carried out carefully to ensure correct operation.
