SUBJECT
Power-Assisted Steering Failure
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)
F80 (M3 Sedan)
F82 (M4 Coupe)
F83 (M4 Convertible)
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)
https://www.bmwtis.net/tiscode/cgi-bin/bulletin.aspx?sie_path=/tsb/bulletins/htm_store/246... 8/6/2015
Page 2 of 4
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).

Vehicle Programming and Coding
If a control module was working properly and it fails to program correctly or requires initialization,
please claim this additional work with the applicable KSD2 labor operations under the defect code listed
above.
The diagnosis and repair of vehicles “arriving” with failed control modules or stored faults which will
cause them to fail during programming cannot be claimed under the defect code listed in this bulletin (See
“Other Repairs” below).
