A faulty ABS sensor is a serious safety issue that should be addressed right away. Without sensing the wheel speed, the ABS and/or DSC system does not know how much braking force to apply or how to modulate the brakes. Since DSC also includes throttle control it may reduce power or give the feeling of traction control kicking in. This can be very dangerous in any condition, even on dry pavement, so it's vital that you replace sensor(s) at the first sign of a fault.

This is an ABS sensor manufactured by Bosch - an original supplier to BMW for many brake components. As an OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
