ALL E91's are NOT alike. Many wiring/fuse/electrical & Module changes over the years, and fault code definition depends upon Module SGBD/Variant. So if you want competent forum help, please provide:
Last-7 Characters of VIN BA541655
Brand/Model of any Scan Tool (Foxwell Model) FOXWELL 510elite
System voltage (measured with DMM at Jumpstart Terminals, or at Lighter Socket), with Engine Running & Alternator Charging? 14.9V

I have a 2010 e91 with DSC error and scan tool indicated rear left wheel sensor
codes: 2F5F 2F61 and 2FE4, i ordered Bosch wheel sensor from FCP end replaced it,no difference.
I tried a washer between the sensor and the carrier, did not help, removed it.
Disconnected ABS unit under the hood and reconnected.

Question i have is there a ring on the CV axle? i need 33207604591 and they are $1400 ouch!
update....
I just did the live data, rear right is ok, rear left is zero, so may be the ring is broken?

Thanks Luuk

I can't tell you about your rear Reluctor/ Bearing. Perhaps someone with 2010 E91/ E90 can offer specific advice. I presume NO work has been done on Left Rear Bearing/ Half-Shaft?

If there was NO indication of wear/damage to end of Sensor you removed (from contact with Reluctor/ Bearing/ Axle, then FIRST suspect would be a wiring fault in the two wires (Blue wire/ Brown wire) between Left Rear Speed Sensor and X1746 Connector at the DSC/DXC, or at the Connectors themselves (X142 & X1746).

I would disconnect BOTH connectors and test for continuity in each wire, as between X142/2 & X1746/33 for Blue Wire & X142/1 & X1746/20 for Brown wire. Also test for short to Chassis Ground and short between X142/1 & X142 (contact between Brown & Blue wires). Check the pins & Sockets for any corrosion, water, bent/broken pin, or loose socket. Clean with Electronic Contact Cleaner & use Wheel Speed Live Data to test again.

ISTA ScreenPrints showing wiring & Connector View are attached to NEXT Post. If testing suggestions (using Multimeter) or additional wiring info is/are desired, please advise.

Attached are ISTA ScreenPrints related to 2010 328iX LR Wheel Speed Sensor, per prior post.

No work was done on the shaft/bearing, just got the abs error 2 weeks ago. Will use the old sensor wiring to short the wires and check at the X1746 connector, thanks for your help

there is a way to monitor measured speed from wheel speed sensors.
note that rear right sensor "looses" speed reading every few seconds.

In my case is was (brand new, oe) bearing reluctor ring
Had to do the bearing twice, grr.
