ABS Fault - Wheel speed sensor - Front left active fault (not reading)

[DetroitP]

Hello: An ABS fault appeared for the front left wheel sensor and as result I have replaced it with a new sensor. That didn't fix the issue, thus, I moved the sensor to the right side to see if fault code moves and it didn't. Then looking through my Schwaben datalogger for all 4 wheel speeds, I see all 3 reporting data while moving in straight line, expect for the front left as indicated by the fault code. However, If I turn or drive in a circular pattern then the faulty wheel speed does read. Any idea what may cause the speed sensor not read while driving in straight line?

Vehicle: 2008 E92 M3, 140k miles, DCT transmission

Active fault codes:
5D91 - DSC: wheel-speed sensor plausibility, front left.
5D96/not present: DSC: wheel-speed sensor direction of rotation front-left
5D90/present: DSC: Wheel speed sensor power supply


many thanks in advance

Have you looked at the wiring? Sounds like a possible broken wire, loose connection, or corrosion.

Yes, I have checked the wires & connection multiple times and everything seemed sound. The only thing I am suspecting at this point is the wheel hub, but I am not aware of how to check it. Any ideas before I attempt to purchase a new hub?

Thanks for the input

Update:
I replaced both front wheel bearings and problem still persists. Any other ideas?

Thanks

Another update:
I pulled the fender liner, and checked the connections and wires. No visible damage of any sort. Any other suggestions I can try?

Thanks in advance
