It is sold singly under the reference numbers 34523420330 and 34523405906. Easy Life Markets sells it for X3 owners and workshops who have traced an ABS or stability control warning to a failed front sensor.\u003c\/p\u003e\n\n\u003cp\u003eEach wheel on the X3 has its own sensor that reads how fast that wheel is turning. The ABS control unit compares the four signals many times a second, and the same data feeds the stability and traction systems. When one sensor stops reporting, the car cannot trust the comparison, so it switches those systems off and lights the warnings on the dash. The brakes still work, but without anti-lock control.
