Your Bmw 740li Xdrive ABS wheel speed sensor is the component that makes anti-lock braking possible on your 740li Xdrive. It monitors the rotational speed of each wheel in real time and sends that data to the Bmw 740li Xdrive ABS control module, which uses it to prevent wheel lockup during emergency stops. When a sensor fails on your 740li Xdrive, 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 740li Xdrive wheel speed data is reaching the module.
The ABS wheel speed sensor on the Bmw 740li Xdrive is an electromagnetic or Hall-effect sensor mounted near each wheel hub or bearing assembly of your 740li Xdrive. It generates an electronic signal as a toothed reluctor ring rotates past it, producing a frequency the 740li Xdrive ABS module interprets as wheel speed. On most modern Bmw 740li Xdrive 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 740li Xdrive systems simultaneously.
GeoBrakes stocks both passive and active ABS wheel speed sensors for the Bmw 740li Xdrive. Passive sensors use an analog signal and are found on older 740li Xdrive 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 740li Xdrive vehicles manufactured after the mid-2000s and are required for full compatibility with modern 740li Xdrive traction and stability control systems.
Signal accuracy matters as much as fitment with Bmw 740li Xdrive wheel speed sensors. A sensor that generates the correct frequency for your 740li Xdrive ABS module ensures consistent ABS calibration, proper traction control thresholds, and accurate stability control response on your Bmw 740li Xdrive. Every sensor in the GeoBrakes catalogue is matched to the Bmw 740li Xdrive through our vehicle selector, with front and rear positions listed separately to eliminate position errors on your 740li Xdrive.
Can I drive my Bmw 740li Xdrive with a faulty ABS wheel speed sensor?
You can drive the Bmw 740li Xdrive with a failed ABS sensor, but the anti-lock braking system on your 740li Xdrive 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 740li Xdrive. Replacing a failed sensor promptly is strongly recommended, particularly before winter.
How do I find the right ABS sensor for my Bmw 740li Xdrive?
Use the GeoBrakes vehicle selector and enter the Bmw 740li Xdrive year, make, and model. The system displays only the sensors confirmed to fit the Bmw 740li Xdrive, with front and rear positions listed separately. Select the position matching the sensor you are replacing on your 740li Xdrive to avoid receiving the wrong unit.
Do I need to replace all four ABS sensors on my Bmw 740li Xdrive at the same time?
No. ABS wheel speed sensors on the Bmw 740li Xdrive are independent components and only the failed unit needs to be replaced. However, if your 740li Xdrive has high mileage and one sensor has failed, it is worth visually inspecting the connectors on the other Bmw 740li Xdrive sensors for corrosion while the wheel is removed.
