BMW 12147503140 Crankshaft Position Sensor is an electronic or sensor-related listing where part number, plug shape and system compatibility are critical. Match the number and connector layout from the original unit before ordering.
Some electronic parts may need diagnosis, coding, calibration or professional installation. The listing does not guarantee that replacing the part will clear a fault without proper checks.
For a sensor or electronic module, the safest match is the part number and connector layout on the old unit. Vehicle symptoms alone are not enough because faults can come from wiring, coding, calibration or another component.
