Need a replacement ABS ring for your BMW 3 Serie 325 D E93? As drivetrain specialists, we supply precision-engineered parts for your convertible. A damaged ABS reluctor ring compromises...
The BMW 3 Serie 325 D E93 is a car that combines muscular diesel performance with the refined open-top driving dynamics of a convertible. To preserve the high safety standards and sharp handling BMW is renowned for, every part of the drivetrain must work in complete harmony. The ABS ring, also known as an ABS reluctor ring or sensor ring, is a compact yet vital component of the vehicle's braking and safety systems. On a rear-wheel-drive model such as the 325 D E93, these components face severe exposure to water, dirt and road salt during harsh European winters. This frequently leads to corrosion, which over time can cause the ring to expand, crack or distort. Choosing a replacement part tailored precisely to the E93 platform is crucial to avoid fault codes and ensure the electronic driver aids can monitor wheel speeds with utmost accuracy.
The ABS ring on your BMW 3 Serie 325 D E93 is mounted on the drive shaft and works as the mechanical counterpart to the ABS wheel speed sensor. As the wheel rotates, the teeth or magnetic windows of the ring pass the sensor, generating an electrical pulse signal. This signal is sent straight to the ABS control unit, which calculates the exact rotational speed of each individual wheel. For a car with the generous torque of the 325 D engine, this interplay between mechanical parts and electronics is fundamental. The information is not only vital for the anti-lock braking system, but it also forms a cornerstone of the Dynamic Stability Control (DSC). If the control unit receives corrupted data due to a damaged ring, it cannot regulate brake pressure or engine output correctly, directly compromising your vehicle's roadholding and your safety.
The most telltale sign that an ABS ring on your BMW 3 Serie 325 D E93 has begun to fail is an illuminated ABS or stability control warning light on your dashboard. Initially, these warnings may appear intermittently, triggered by moisture or road vibrations. Another very common symptom is unwanted ABS activation during low-speed braking on dry tarmac, felt as a distinct judder or pulsing through the brake pedal just before the car comes to a stop. This usually happens because rust develops beneath the ring on the shaft, pushing it outwards until it fractures. Once cracked, the gap between teeth becomes uneven, tricking the sensor into registering wheel lock-up. A visual check will often reveal whether the ring is cracked or has expanded enough to rub against the ABS sensor head.
Identifying the correct ABS ring for your BMW 3 Serie 325 D E93 requires attention to detail, as dimensions can differ depending on the chassis number and production period. You need to match the internal diameter, external diameter and tooth count so that the signal frequency remains accurate. The most reliable way to find the right part is to filter by your car's make, model and engine variant in our shop. This guarantees you view only the components verified for your exact vehicle. When carrying out the replacement, the mounting seat on the outer CV joint must be thoroughly cleaned of rust, scale and road grime. Pressing a new ring onto an uneven surface risks cracking it immediately or seating it out of true, triggering persistent fault codes. We ensure you get the right replacement for your BMW 3 Serie 325 D E93 quickly and easily.

When one drivetrain component shows wear, neighbouring parts on the same car often require attention as well. By checking these exact pages for the BMW 3 Serie 325 D E93, you can more easily determine whether the issue lies purely with the ABS ring or another related part of the transmission system.
This is especially important on models where vibrations, play and unusual noises can transfer symptoms across several driveline components. Inspecting related categories minimises the risk of replacing one correct part while overlooking an adjacent component that contributes to the very same issue.
By acting proactively and replacing perished CV boots or worn joints alongside your new ABS ring, you ensure lasting reliability for your BMW.

The most common signs are the ABS light illuminating, stability control warning messages, or the brake pedal pulsating when braking at low speeds despite dry road conditions.
No, on the BMW E93 you can usually replace just the ABS ring. However, this requires removing the drive shaft and thoroughly cleaning the mounting surface before pressing the new ring into place.
The primary cause is corrosion. Rust builds up beneath the ring on the drive shaft, creating pressure that eventually causes the ring to crack or distort so that the sensor can no longer read it correctly.
The car can still be driven, but active safety systems such as ABS and DSC (dynamic stability control) are likely deactivated. This increases the risk of skidding and wheel lock-up under emergency braking, so the fault should be rectified promptly.
No, if the ABS warning light is illuminated or the system fails during the test procedure, the car will fail its inspection and require a retest.
The most reliable method is to select your vehicle's make, model, and engine variant in our store selector. This filters for the exact dimensions and tooth count needed for your BMW 325 D E93.
