Original BMW Crankshaft Position Sensor Reluctor for BMW 1–7 Series, M2, M3, M4, X1, X3, X4, X5, X6, and Z4 (2009–2021)

The crankshaft position sensor reads this Original BMW reluctor, which supplies the crank position signal on 2009–2021 BMW 1 through 7 Series, M2, M3, M4, X1, X3, X4, X5, X6, and Z4 models. A reluctor is a toothed ring whose teeth pass the tip of a sensor as the engine turns, and the engine control unit uses the resulting signal to track crankshaft position and speed for ignition and injection timing. BMW calls this part simply a reluctor. It weighs 66 g (0.1 lb), is made in Germany, and is sold as a single piece. Production under this number began in September 2009.

Common Questions

Is this the crankshaft position sensor itself?
No. This is the toothed reluctor the sensor reads, and the sensor is a separate part.

Does the M2 Competition use this reluctor?
Yes. BMW's data covers the F87 M2 Competition with the S55 engine as well as the earlier N55 M2, and the same number appears on the M4 GTS and M4 CS.
