SUBJECT

Power-Assisted Steering Failure

October 2014
Technical Service

SB-10057531-7850

MODEL

F22 (2 Series Coupe)
F30 (3 Series Sedan)
F31 (3 Series Sport Wagon)
F32 (4 Series Coupe)
F34 (3 Series Gran Turismo)
F36 (4 Series Gran Coupe)
SITUATION

The power-assisted steering fails with a warning lamp in the instrument cluster or a check control message in the
Central Information Display. In some cases, the Dynamic Stability Control warning lamp (DSC) in the instrument
cluster may also be illuminated.
CAUSE

Failure of the power-assisted steering may be caused by various software-related issues.
The following codes may be stored in the fault memory of the Electric Power Steering (EPS):
Scenario 1: 0x4823E1
Scenario 2: 0x4823CB/0x4823CC
Scenario 3: 0x4823D2 and/or 0x4823EC
Scenario 4: 0x48239C (DSC warning lamp lights up in the instrument cluster)
Scenario 5: No communication with the EPS is possible (not accessible using diagnostics)
Scenario 6: 0x4823EE and 0x4823C2
CORRECTION

Run diagnostics with the latest version of ISTA/D to read stored fault codes
Scenario 1: (0x4823E1)
Program the vehicle with ISTA/P 2.51.2 (target I-Level F020-13-11-502), or a more recent version.
Scenario 2: (0x4823CB / 0x4823CC)
Program the vehicle with ISTA/P 2.52.0 (target I-Level F020-14-03-502), or a more recent version.
Scenario 3: (0x4823D2 and/or 0x4823EC)
Program the vehicle with ISTA/P 2.51.2 (target I-Level F020-13-11-502), or a more recent version.

Scenario 4: (0x48239C)
For this fault code memory, the DSC warning lamp lights up in the instrument cluster. The power-assisted steering
is working, but the DSC is not fully functional (although ABS is still operational). Program the vehicle with
ISTA/P 2.51.2 (target I-Level F020-13-11-502), or a more recent version.
Scenario 5: (No communication with the EPS possible)
The vehicle cannot communicate with the EPS (not accessible using diagnostics). Disconnect the battery for at
least ten minutes and then reconnect it. The EPS is then accessible again. Then program the vehicle using ISTA/P
2.52.0 (target I-Level F020-14-03-502), or a more recent version.
Scenario 6: (0x4823EE and 0x4823C2)
Perform the "Starting Steering" test plan (AT3244_EPS_ZF1_INBTR) from the Service Functions and then switch
the ignition off and on again. Read the fault code memory again, and then clear it. Do not replace the EPS unit for
this condition.
Note that ISTA/P will automatically reprogram and code all programmable control modules that do not have the
latest software. For information on programming and coding with ISTA/P, refer to CenterNet / Aftersales Portal /
Service / Workshop Technology / Vehicle Programming.
Always connect a BMW approved battery charger/power supply (SI B04 23 10).
