BMW Rear ABS Wheel Speed Sensor | Rear Left & Right Brake Radar Spares

Description

Restore the absolute precision of your vehicle’s dynamic braking control, active stability matrix, and driver assistance networks with this premium BMW Rear ABS Wheel Speed Sensor (Rear Left or Right ABS Pulse Sensor). Sourced and extensively verified for premium BMW sedan, touring, and SUV platforms, this genuine digital magnetic sensor is the definitive replacement for vehicles experiencing sudden traction control dropouts, a yellow or red brake warning light on the dash, or an immediate “ABS / Stability Control Failure” message across the central infotainment display.

The Rear ABS Wheel Speed Sensor sits mounted through the rear wheel hub carrier assembly, positioned mere millimeters away from a spinning magnetic reluctor ring on the rear drive axle or wheel bearing. By utilizing the Hall-effect principle, this sensor tracks the exact rotational speed of the rear wheels and broadcasts high-frequency square-wave digital signals straight to the central DSC (Dynamic Stability Control) module. The DSC brain continuously analyzes this data package to coordinate safety systems—including anti-lock braking prevention, cornering brake management, cruise control acceleration parameters, and even your vehicle’s speed-sensitive power steering weight.

Because these sensors are positioned low down within the rear wheel arches, they operate in a harsh, high-vibration environment. Over time, the exposed wiring loom leading to the hub can flex, stretch, and crack due to normal suspension travel. Additionally, fine metallic brake dust, corrosive road grime, and rainwater can bypass the rubber sealing rings, bridging the sensor tip and short-circuiting the internal micro-resistors. When an ABS sensor fails, the DSC module loses all data for that wheel and instantly deactivates the vehicle’s electronic safety nets as a precaution. This results in heavy, unassisted low-speed steering, the complete loss of anti-lock braking functionality, and a disabled cruise control network. Swapping out a dead sensor node with this workshop-verified factory unit restores seamless communication across your vehicle’s $CAN-bus$ network.

Manufactured with high-durability, heat-shielded wiring insulation and a precision-molded composite sensor probe, this unit drops straight into the original factory hub bore.
