ABS rings for BMW 1 Serie 120 D E87

ABS rings for BMW 1 Serie 120 D E87

Maintaining the braking system and safety functions on your BMW 1 Serie 120 D E87 is vital for both driving pleasure and road safety. The ABS ring, often called an ABS reluctor ring, is a small yet fundamental component of your vehicle's anti-lock braking system. On the E87 generation of BMW's 1 Series in particular, these rings are prone to corrosion over time, which can trigger faulty wheel-speed readings. Here at CVJoint24, you will find dedicated ABS rings engineered to meet the technical demands of your 120 D. We focus on providing parts with the exact dimensions and tooth count required to ensure your sensors read wheel speeds without interference. Choosing the right spare part straight away minimises unnecessary garage visits and keeps your BMW performing as it should on the road.

What does the ABS ring do on a BMW 1 Serie 120 D E87?

The ABS ring on a BMW 1 Serie 120 D E87 acts as a pulse generator for the vehicle's electronic management systems. Fitted to the drive shaft, it rotates at the exact same speed as the wheel. A magnetic sensor positioned directly above the ring's teeth reads the magnetic pulses generated as each tooth passes by. This data is transmitted to the ABS control unit, which calculates whether a wheel is locking up during braking or slipping under acceleration. For a rear-wheel-drive car like the 120 D E87, this setup is crucial for maintaining stability via Dynamic Stability Control (DSC). If the ring becomes damaged, cracked or heavily corroded, the system loses a reliable signal and will disable safety features to prevent unintended interventions.

Common signs of wear

There are several clear symptoms indicating that the ABS ring on your BMW 1 Serie 120 D E87 is failing. The most frequent sign is the ABS warning light or traction control light illuminating on your dashboard. This fault often appears intermittently at first, especially in damp conditions or after washing the car. Another telltale sign is unwanted ABS pulsing through the brake pedal during gentle stops on dry tarmac, caused by the control unit receiving incorrect wheel-speed data. On BMW E87 models, rust typically builds up on the driveshaft beneath the ring. This corrosion forces the ring to expand until it rubs against the ABS sensor tip, which not only ruins the ring itself but can also destroy the more expensive sensor if left unresolved.

How to choose the correct ABS ring

When selecting a replacement ABS ring for your BMW 1 Serie 120 D E87, precision is essential. It is not enough to know simply that you drive a 1 Series; different engine options and model years within the E87 platform can feature different drive shaft dimensions. You need to verify the inner diameter, outer diameter and number of teeth on the ring. An incorrect ring will either fail to seat on the shaft or send inaccurate speed readings to the car's computer. To make selection straightforward, use our model selector by picking your vehicle make, model and engine variant. Filtering by your exact car ensures fully compatible ABS rings and an accurate fit every time.

Related parts to inspect

Please also check these exact pages for the same vehicle when working with the ABS ring:

When a drivetrain part shows wear, neighbouring components on the vehicle often require attention too. Comparing these exact pages for the BMW 1 Serie 120 D E87 makes it simpler to determine whether an issue lies purely with the ABS ring or another related driveline section.

This is especially true on models where vibrations, play and unusual noises can transfer symptoms across several parts of the same drivetrain. A quick check of related categories reduces the risk of replacing the right type of component while overlooking an adjacent part causing the same fault.
