M4 Wheel Speed Sensor 1B0A67, ABS, and rear diff lock limited

[M4Ops]

I started getting the errors many others have reported about wheel speed sensor issues: ABS, Rear Diff Lock, frontal collision system deactivated, pedestrian warning system deactivated and rough road detected(1B0A21. In my instance, the error log seems to suggest the front right sensor according to BM3 diagnostic logs.

1B0A21-rough road detection. No receive wheel speed.

1B0A61-vehicle speed plausibility. Minimum speed in overrun implausible

1B0A67-vehicle speed. Wheel speed front/right signal 0/00 change: implausible.


At one point the errors went away after the car had been sitting for a couple weeks then popped back on a few days ago.. tried clearing the errors but they come right back.. I'll be ordering a new front right wheel sensor. Just wondering if there's anything else I should check or do while I'm at it.


Thank you in advance.
