ABS rings for Volvo V40 1.8 I
When it comes to safety in your Volvo V40 1.8 I, the ABS system is one of the most critical components for a stable driving experience. The ABS ring, also known as a sensor ring or reluctor ring, plays a pivotal role in this system by enabling precise monitoring of wheel speed. For owners of a Volvo V40 1.8 I, it is vital to choose a ring specifically tailored to the car's technical specifications and drivetrain design. A damaged or cracked ring can prevent safety systems from operating correctly, impairing both braking performance and vehicle stability. At CVJoint24, we specialise in these exact components to help you drive safely and confidently on the road in all weather conditions.
What does the ABS ring do on a Volvo V40 1.8 I?
The ABS ring on a Volvo V40 1.8 I is mounted on the outer CV joint and functions as an integral part of the car's anti-lock braking system. Its primary role is to supply the ABS sensor with a clear, steady signal regarding the wheel's exact rotational speed. The ring features a specific number of teeth or slots that the sensor reads magnetically as the wheel rotates. This movement generates an electrical pulse transmitted directly to the car's engine control unit (ECU). If the ECU detects that one wheel is rotating slower than the others under braking—indicating that a wheel is about to lock up—it modulates the brake pressure immediately. This is crucial for maintaining steering control during heavy braking, especially on slippery surfaces such as ice or wet tarmac.
Common signs of wear
The most common symptom of a broken or worn ABS ring on your Volvo V40 1.8 I is an illuminated ABS warning light on the dashboard. This is frequently caused by the ring cracking due to corrosion developing beneath it. When rust forms between the CV joint and the ring, the material expands and exerts immense outward pressure, ultimately snapping the ring. You may also notice an unusual pulsing or vibration through the brake pedal during normal braking at low speeds, just before the car comes to a complete halt. This happens because the sensor misinterprets the irregular tooth spacing of the cracked ring as wheel lockup. In some cases, the car's traction control system may also trigger warning lights or intervene unnecessarily, causing an erratic and unsettled driving feel. If you notice these symptoms, it is time for a thorough inspection of the rings.
How to choose the correct ABS ring
Selecting the correct ABS ring for your Volvo V40 1.8 I demands precision. Variations exist depending on the exact model year and the specific type of CV joint installed on your vehicle. The most critical dimensions are the number of teeth and the inner diameter, as these must match the original part exactly for the sensor to deliver an accurate signal. The simplest and most reliable way to select the right component on cvjoint24.com is to filter by your car's exact make, model and engine variant. This ensures you find options that are fully compatible with your specific Volvo V40 1.8 I. We always recommend choosing a ring manufactured from high-grade steel with robust anti-corrosion protection, as harsh European winters and salted roads are the main cause of premature component failure.
Related parts to inspect
Please also check these exact pages for the same vehicle when working on the ABS ring:
When one drivetrain component shows signs of wear, nearby parts on the same car often warrant inspection too. By comparing these exact pages for your Volvo V40 1.8 I, you can easily determine whether the issue lies purely with the ABS ring or with another related section of the driveline.
This is especially important on models where vibrations, play and strange noises can transfer across multiple drivetrain components. A quick check of related categories reduces the risk of replacing one correct part while overlooking an adjacent component that causes the same symptom.
Addressing multiple minor issues at the same time saves both time and money in the long run, ensuring your Volvo remains dependable for many kilometres to come.

Frequently asked questions about ABS rings for Volvo V40 1.8 I
How do I know if the ABS ring fits my Volvo V40 1.8 I?
The most reliable way is to select your car's exact make, model and engine variant in our search filter. We match part specifications, such as tooth count and diameter, against your car's original equipment to ensure an exact fit.
Can I replace just the ABS ring, or do I have to replace the complete CV joint?
On the Volvo V40 1.8 I, you can often simply replace the ring on its own if the CV joint itself is otherwise in good condition. This is a very cost-effective alternative to replacing the complete unit.
Why do ABS rings crack so often on the Volvo V40?
The most common cause is corrosion forming on the CV joint beneath the ring. As the rust expands, it exerts outward pressure that eventually causes the steel ring to snap, which is particularly common in harsh winter conditions with road salt.
What happens if I continue driving with a broken ABS ring?
Besides the ABS system failing to work properly, which increases the risk of wheel lock-up under heavy braking, your car will not pass its mandatory annual inspection with an active ABS warning light illuminated.
Do I need specialist tools to fit a new ABS ring?
No advanced specialist tools are required, but thoroughly cleaning all corrosion from the mounting surface on the CV joint is vital. The ring can then be gently heated or pressed into place so it seats firmly.
Do you offer a fitment guarantee when I order parts from you?
Yes, we always provide a fitment guarantee when you choose your car's make, model and engine variant. That means we take full responsibility for ensuring the ABS ring you order truly fits your Volvo V40 1.8 I.
