Your Bmw M4 ABS wheel speed sensor is the component that makes anti-lock braking possible on your M4. It monitors the rotational speed of each wheel in real time and sends that data to the Bmw M4 ABS control module, which uses it to prevent wheel lockup during emergency stops. When a sensor fails on your M4, your ABS loses the input it needs. On wet, icy, or gravel road surfaces, the difference between a controlled stop and a skid can come down to whether your Bmw M4 wheel speed data is reaching the module.
The ABS wheel speed sensor on the Bmw M4 is an electromagnetic or Hall-effect sensor mounted near each wheel hub or bearing assembly of your M4. It generates an electronic signal as a toothed reluctor ring rotates past it, producing a frequency the M4 ABS module interprets as wheel speed. On most modern Bmw M4 vehicles, this same data feeds the traction control system, electronic stability control, and electronic brake force distribution, making a functioning wheel speed sensor critical to the safe operation of multiple M4 systems simultaneously.
GeoBrakes stocks both passive and active ABS wheel speed sensors for the Bmw M4. Passive sensors use an analog signal and are found on older M4 vehicles and many trucks still in service. Active Hall-effect sensors require a small power supply and output a clean digital signal, offering greater accuracy at very low speeds. Active sensors are standard on most Bmw M4 vehicles manufactured after the mid-2000s and are required for full compatibility with modern M4 traction and stability control systems.
Signal accuracy matters as much as fitment with Bmw M4 wheel speed sensors. A sensor that generates the correct frequency for your M4 ABS module ensures consistent ABS calibration, proper traction control thresholds, and accurate stability control response on your Bmw M4. Every sensor in the GeoBrakes catalogue is matched to the Bmw M4 through our vehicle selector, with front and rear positions listed separately to eliminate position errors on your M4.
Can I drive my Bmw M4 with a faulty ABS wheel speed sensor?
You can drive the Bmw M4 with a failed ABS sensor, but the anti-lock braking system on your M4 will be completely disabled. On icy or wet American roads, this significantly increases stopping distances and the risk of losing steering control during hard braking on your Bmw M4. Replacing a failed sensor promptly is strongly recommended, particularly before winter.
How do I find the right ABS sensor for my Bmw M4?
Use the GeoBrakes vehicle selector and enter the Bmw M4 year, make, and model. The system displays only the sensors confirmed to fit the Bmw M4, with front and rear positions listed separately. Select the position matching the sensor you are replacing on your M4 to avoid receiving the wrong unit.
Do I need to replace all four ABS sensors on my Bmw M4 at the same time?
No. ABS wheel speed sensors on the Bmw M4 are independent components and only the failed unit needs to be replaced. However, if your M4 has high mileage and one sensor has failed, it is worth visually inspecting the connectors on the other Bmw M4 sensors for corrosion while the wheel is removed.
