Purpose and function of the ABS sensor

The ABS sensor mounted on the rear axle in BMW E70 and E71 models is responsible for transmitting information about wheel rotational speed to the controller. Based on this data, the anti-lock braking system can limit slippage during braking, which improves vehicle control on wet, slippery, or uneven surfaces. A properly functioning ABS sensor is crucial for driving stability and the effectiveness of electronic brake assist systems.

Vehicle placement and compatibility

The presented sensor is designed for installation on the rear axle, with the possibility of application on both the left and right sides. This solution facilitates part selection during repairs – one type of sensor can serve both sides of the vehicle, which simplifies service logistics and reduces the risk of ordering errors. Placement on the rear wheels means the component operates in demanding conditions (dirt, moisture, temperature changes), which is why its efficiency has a direct impact on the correct operation of the ABS system.

Product characteristics and advantages of use

The ABS sensor from this offer belongs to the Other brake sensors and switches group, which means it works with other elements of the braking system and the vehicle's electronic systems. Using an original BMW solution allows you to maintain compatibility with the factory installation, proper signal parameters, and correct cooperation with the control module. This is particularly important in vehicles equipped with advanced safety systems that rely on accurate data from wheel speed sensors.

By choosing this element, you gain:

• a component matched to the electrical architecture of the BMW E70/E71,
• a stable signal for the rear axle ABS system,
• the possibility of application on the left or right side,
• a service solution that restores the correct operation of the braking system.

Used condition – an informed service choice

The offered ABS sensor is a used item, which is an attractive alternative to new parts, especially for maintenance repairs in older vehicles. Such components, sourced from disassembly, allow for reduced service costs while maintaining compliance with factory specifications. For many BMW users, this is a reasonable compromise between price and functionality, especially when the priority is to restore the efficiency of the ABS system without investing in a completely new assembly.
