ABS rings for Volvo V40 T4

ABS rings for Volvo V40 T4

The ABS ring is a small yet vital component on your Volvo V40 T4. This specific model variant requires parts engineered to handle the power and dynamics delivered by the T4 engine. A properly functioning ABS ring is essential for the anti-lock braking system to communicate accurately with the electronic control unit. At CVJoint24, we specialise in these precise driveline components to help you maintain your car's original safety performance. Our rings are manufactured with high precision to withstand the stresses of both city driving and demanding motorway journeys.

Choosing the correct part for a Volvo V40 T4 means taking into account the exact technical specifications set by Volvo for this platform. Because the ABS reluctor ring is constantly exposed to moisture, road salt, and harsh temperature swings, the choice of material is critical. We only supply car parts that meet our strict quality requirements, ensuring long service life and dependable function in all driving conditions.

What does the ABS ring do on a Volvo V40 T4?

The ABS ring, also known as a sensor ring or reluctor ring, is mounted on the CV joint or drive shaft. Its primary task is to generate magnetic pulses as the wheel rotates, which are then detected by the ABS sensor. On a Volvo V40 T4, this system is integrated with both the anti-lock brakes and the car's dynamic stability and traction control (DSTC). Without correct signals from the ABS ring, the system cannot detect whether a wheel is locking up or losing grip.

When you drive your T4, the vehicle safety systems rely on each wheel reporting its precise speed. If the ring is damaged, cracked, or corroded, the signal becomes erratic, which can cause the ABS to intervene unnecessarily or disengage entirely. This affects not only braking performance but also how power is distributed across the wheels—particularly noticeable in a performance model like the T4, where the drivetrain works hard to optimise grip.

Common signs of wear and failure

The most common problem with an ABS ring on the Volvo V40 T4 is cracking caused by corrosion. As rust develops underneath the ring, the expanding metal pushes outward until the ring fractures. A clear sign of this is an illuminated ABS warning light on your dashboard. You may also notice a pulsating brake pedal or unwanted ABS activation during low-speed braking on dry, smooth tarmac. This happens because the sensor miscounts teeth when passing over the crack in the ring.

Beyond dashboard warnings, fault codes may be stored in the car's diagnostic system pointing to a specific wheel speed sensor. In many cases, the sensor itself is intact—the issue is simply a failed ABS ring. If you hear a scraping noise from the wheel arch, it may also indicate that a loose or cracked ring is rubbing against the sensor or other suspension components. Ignoring these signs can lead to more costly repairs if the sensor suffers mechanical damage.

How to choose the correct ABS ring

To ensure you get the correct ABS ring for your Volvo V40 T4, it is essential to check the tooth count and the physical dimensions of the ring. Even though the T4 is a distinct engine variant, differences can occur depending on the model year and factory equipment. The most reliable way to find the right part is to select your car's exact make, model and engine in our vehicle picker. This filters our catalogue to show only components guaranteed to fit your specific drivetrain.

When sourcing parts from us, you can rely on our specialised driveline expertise. We always recommend inspecting the condition of the outer CV joint whenever replacing an ABS ring, as the ring is often pressed directly onto it. If the constant velocity joint shows signs of wear, replacing the entire assembly at the same time is frequently the most economical route. With our perfect-fit guarantee, you can order with confidence knowing the part will install seamlessly without modification.

Related parts to inspect

We recommend also checking these exact pages for the same car when working with the ABS ring:

When one driveline component shows signs of wear, neighbouring parts on the same vehicle should be inspected as well. By comparing these exact pages for the Volvo V40 T4, it becomes much easier to determine whether the fault lies strictly with the ABS ring or another related drivetrain component.

This is particularly relevant on models where vibrations, play, and noises can transfer between multiple components along the same driveline. A quick check of related categories reduces the risk of replacing one correct part while missing a connected component that contributes to the same issue.

• Volvo V40 T4
• Drive shafts for Volvo V40 T4
• Outer CV joints for Volvo V40 T4
• Inner CV joints for Volvo V40 T4

By proactively checking these components, you can prevent future breakdowns. If you notice vibrations during acceleration or clicking sounds on full steering lock, these are classic signs of a failing CV joint. Replacing worn spare parts early saves money in the long run and keeps your journey safe.
