ABS rings for BMW 3 Serie 320 I E93
The BMW 3 Serie 320 I E93, the elegant convertible model of the E90 generation, requires precision in every component to preserve its renowned driving dynamics and safety. The ABS ring, also known as an ABS reluctor ring or sensor ring, is a small but vital part of the car's braking and stability systems. On a rear-wheel-drive car such as the 320 I E93, these components endure severe stress from both weather and mechanical loads. Choosing a high-quality ABS ring is critical to ensure that the car's electronic driver assistance systems work properly in all driving conditions.
When you shop with us at cvjoint24.com, you get access to a range that has been carefully selected to suit your specific BMW. We understand that owners of a 3 Serie value reliability and performance. That is why we supply only parts that meet rigorous standards for materials and precise fitment. By replacing a defective ABS ring in good time, you can prevent more expensive repairs to the complete drive shaft and ensure that your car remains safe on the road.
What does an ABS ring do on a BMW 3 Serie 320 I E93?
The ABS ring on your BMW 3 Serie 320 I E93 serves to supply the vehicle control unit with precise information regarding wheel rotation speed. The ring is fitted to the drive shaft and features a specific number of teeth or magnetic windows that pass a stationary ABS sensor. As the wheel turns, an electrical pulse is generated and sent to the car's ABS module. This data is not only used for the anti-lock brakes, but also serves as critical input for Dynamic Stability Control (DSC) and the traction control system.
For a BMW 320 I E93, this system is particularly important as it helps manage power delivery to the rear wheels, especially during acceleration on slippery surfaces or under enthusiastic driving. If the ABS ring sends inaccurate signals, the system may assume a wheel is locking up or losing traction, resulting in unwanted braking intervention or complete deactivation of the safety systems. A properly functioning ring is therefore essential for the car's advanced safety technology to protect you and your passengers.
Common signs of wear
The most common problem with ABS rings on BMW models such as the E93 is corrosion. Because the ring sits exposed at the wheel hub, moisture and road salt penetrate between the ring and the drive shaft. This causes rust to build up, which forces the ring to expand. Once swollen, the ring can eventually crack or begin to rub against the ABS sensor, ruining both components. A clear symptom is the ABS warning light illuminating on the dashboard, often alongside warning lights for traction control and stability control.
Another symptom is a pulsating sensation in the brake pedal during completely normal braking at low speeds, even on dry, smooth tarmac. This occurs because the control unit receives an irregular signal from the damaged ring and assumes the wheel is about to lock. If you notice that your cruise control stops working or the steering feels unusual, this can also stem from faulty wheel-speed data. Ignoring these warning signs can leave the ABS system unable to intervene in an emergency.
How to choose the correct ABS ring
Choosing the correct ABS ring for a BMW 3 Serie 320 I E93 demands attention to detail. Variations exist depending on the production year and specific drivetrain. The most critical step is to verify the ring's inside diameter, outside diameter and tooth count. On the E93 model, the ring is typically integrated in a way that requires exact dimensions to achieve the correct press-fit on the drive shaft. A ring that is too loose will migrate along the shaft, whereas one that is too tight may crack during installation.
We strongly recommend selecting your car's make, model and engine in our vehicle selector to filter out the components specifically tailored to your car. This eliminates the risk of incorrect orders and ensures you receive a part with the correct specifications. Our fitment guarantee means we take full responsibility for the component fitting your car model provided you have selected the correct vehicle details. Investing in the right part from the outset saves both time in the garage and future frustration.
Related parts to check
Be sure to check 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 inspection as well. By comparing these exact pages for the BMW 3 Serie 320 I E93, it becomes much easier to determine whether the fault lies strictly with the ABS ring or another related part of the driveline.
This is especially true on models where vibrations, play and unwanted noises can transfer symptoms across multiple drivetrain components. A quick check of related categories minimises the risk of replacing the right part type while overlooking an adjacent component that causes the same symptom.

- Outer CV joints for BMW 3 Serie 320 I E93
- Inner CV joints for BMW 3 Serie 320 I E93
While you are working on the ABS ring on your BMW, it is an ideal opportunity to inspect the remainder of the drivetrain. In many cases, rust build-up on the drive shaft itself causes the ring to split, so inspect the condition of your drive shaft for the BMW 3 Serie 320 I E93 thoroughly. If the shaft is heavily corroded, seating a new ring securely can be difficult, making a complete driveshaft replacement the most durable fix.
Take the opportunity to inspect the rubber boots on your outer and inner CV joints for the BMW 3 Serie 320 I E93 as well. If a CV boot is split, road dirt penetrates quickly and destroys the joint. Here is a checklist of components that often warrant inspection at the same time:
- ABS sensor (check for rub marks caused by a swollen reluctor ring)
- Drive shaft boots (look for splits or escaping grease)
- Wheel bearings (listen for humming or play when the wheel is spun freely)
- Brake discs and pads

Frequently asked questions about ABS rings for BMW 3 Serie 320 I E93
What are the most common symptoms of a broken ABS ring on a BMW E93?
The most common signs are the ABS and DSC warning lights illuminating, as well as pulsations in the brake pedal when braking at low speeds on dry surfaces.
Can I replace just the ABS ring, or do I need to replace the entire drive shaft?
On the BMW 320 I E93, it is often possible to replace just the ABS ring if the drive shaft is otherwise in good condition. This is a significantly more cost-effective solution than replacing the complete shaft.
Why does the ABS ring crack on my BMW?
This is usually caused by corrosion beneath the ring. Rust builds up between the ring and the drive shaft, creating pressure that eventually causes the ring to expand and crack.
How do I know which ABS ring fits my 320 I E93?
The most reliable method is to select your vehicle's make, model and engine variant in our search filter. We then match your car's details to the correct dimensions and tooth count.
Does a damaged ABS ring affect the car's stability control system?
Yes, because the DSC system uses data from the ABS ring to monitor wheel spin and stability, these functions will often be deactivated if the reluctor ring is defective.
Is a fitment guarantee included when I buy an ABS ring from you?
Yes, we always provide a fitment guarantee when you select your vehicle's exact make, model and engine, ensuring that the part fits your BMW 3 Serie 320 I E93.
