Front ABS/DSC Wheel Speed Sensor (Left/Right), OEM - G42, G87, G20, G80, G22/G26, G82

This part is listed by BMW as BMW part number 34521544002 (34 52 1 544 002) and is described as the left/right front ABS/DSC Wheel Speed Sensor for G42, G87 M2, G20 3-series, G80 M3, G22/G23 4-series, G82 M4. BMW calls it a "Pulse Generator". The sensor is the same for the left or right (but sold individually).

Only for rear-wheel drive models. Does not fit xDrive applications.

The ABS and DSC control unit relies on information from the sensors to set braking and traction control settings. A sensor going bad or failed will set the system into a dangerous failsafe setting and possibly a limp mode. This is a OEM wheel speed/ABS/DSC sensor, made to the same specifications as the BMW engineers intended.

This is an OEM G20/G80 DSC sensor manufactured by ATE - the original supplier to BMW for this part, as well as many other brake components. As the 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.
