When you need a replacement ABS ring for your diesel-powered, front-wheel-drive Volvo S40 1.9 TD, you have come to the right place. This page is dedicated to reluctor rings tailored...
The Volvo S40 1.9 TD is a model renowned for its reliability, but like any vehicle, its safety systems require proper maintenance. The ABS ring, also known as a reluctor ring, is a small yet crucial part of the car's braking system. For the 1.9 TD variant, which often covers many kilometres as a reliable workhorse or commuter car, keeping these components in top condition is vital. We supply ABS rings specifically engineered to meet the technical demands of this specific drivetrain. By selecting a replacement part precision-matched to your model, you maintain your vehicle's original safety characteristics and ensure that the anti-lock brakes perform optimally under all driving conditions.
Driving a Volvo comes with a commitment to safety, and the ABS system sits at the heart of the car's active safety features. A damaged ring might seem minor, but its impact on your car's ability to handle emergency situations is significant. Our products are tested to withstand demanding European road conditions with winter road salt and harsh temperature swings—especially critical for components located in such exposed positions near the wheel hubs.
The ABS ring on a Volvo S40 1.9 TD is mounted on the outer CV joint and operates as part of an inductive measuring system. As the wheel rotates, the teeth on the ring pass a stationary ABS sensor. This generates an electrical pulse sent directly to the car's engine control unit (ECU). The control unit uses this data to calculate the exact rotational speed of each wheel. If the system detects that one wheel is rotating significantly slower than the others under braking—indicating that it is beginning to lock up—it modulates the brake pressure in a fraction of a second.
For a front-wheel-drive car like the S40 1.9 TD, this system is essential for maintaining steering control under heavy braking. Without a properly functioning ABS ring, the ECU cannot receive the necessary readings, resulting in the complete deactivation of the ABS function. This leaves the car behaving like an older vehicle without anti-lock brakes, substantially increasing the risk of skidding and loss of control on slippery roads or during emergency stops.
The most obvious sign that an ABS ring on your Volvo S40 1.9 TD has failed is the illumination of the ABS warning light on your dashboard. This frequently happens when the ring has cracked due to rust expanding beneath it, causing it to swell and misalign the tooth pitch. Another common symptom is "false" ABS intervention. This feels like a pulsation through the brake pedal during normal, low-speed braking on dry tarmac. It occurs because the sensor receives an erratic signal from the damaged reluctor ring.
In addition to dashboard warnings, you might hear a faint scraping noise if the ring has come completely loose and is rubbing against the sensor or splash shield. Because the Volvo S40 1.9 TD is frequently driven in regions where road grit and salt are used, corrosion is the primary reason these rings fail. Inspecting the rings visually when changing tyres can save both time and money, as a cracked ring is usually easy to spot for a trained eye.
When purchasing a replacement ABS ring for your Volvo S40 1.9 TD, precision is paramount. Different ring variations exist depending on the exact build date and vehicle specifications. The most critical dimensions to check are the tooth count (number of teeth) on the ring and its inner diameter. A ring with the wrong number of teeth will send inaccurate wheel speed signals to the computer, preventing proper calibration. To make selecting your parts simple and accurate, we always recommend filtering by your car's exact make, model and engine variant.
Selecting your exact vehicle details brings up parts verified to fit your car, eliminating the hassle of dismantling the vehicle only to find a spare part that does not fit. Remember that an ABS ring is a precision component; it must sit firmly on the CV joint without any play. We ensure you get the exact specifications required, allowing for a smooth installation and flawless operation right from the start.
Be sure to check these dedicated pages for the same vehicle when working on the ABS ring:
When one drivetrain component exhibits wear, adjacent parts on the same car often warrant inspection too. Comparing these exact pages for the Volvo S40 1.9 TD makes it easier to determine whether the fault lies with the ABS ring itself or in another neighbouring section of the transmission line.
This is particularly relevant on models where vibration, play and noises can transfer symptoms across several driveline components. Checking related categories reduces the risk of replacing one worn item while missing a nearby part that contributes to the very same issue.
Replacing an ABS ring provides an ideal opportunity to check over the rest of the car's drivetrain. Since the ring is seated on the outer CV joint, you should inspect the CV boot thoroughly. If the boot is split, dirt and moisture penetrate the joint, quickly destroying both the constant velocity joint and the new ring. If your outer CV joint for the Volvo S40 1.9 TD displays signs of wear, such as clicking noises on full steering lock, it may be more cost-effective to renew the complete joint, which often comes with a new ring already pre-installed.
Key components to check during the repair include:

The most common signs are an ABS warning light remaining on continuously, or a pulsing vibration through the brake pedal when braking at low speeds on dry surfaces. A visual inspection will often reveal cracks in the ring.
On the Volvo S40 1.9 TD, you can usually replace just the ABS ring provided the rest of the CV joint is in good condition. However, it requires thorough cleaning of the mounting surface to ensure the new ring seats correctly.
The primary cause is corrosion. Rust builds up beneath the ring on the CV joint, exerting outward pressure that eventually causes the ring to fracture. This is especially common in harsh European winter conditions.
Yes, if the ABS warning light is illuminated or the system does not operate correctly, your Volvo S40 1.9 TD will fail its roadworthiness inspection or MOT test, as it is a critical safety system.
The tooth count can vary. The most reliable way to find the correct number of teeth is to select your exact model and engine on our website, where we list precise technical specifications for your vehicle's configuration.
It requires some mechanical experience, as you need to expose the CV joint. The ring is usually pressed or gently heated into position. If you are uncertain, we recommend consulting a professional garage, although the part itself is accurately tailored for confident DIY mechanics.
