<\/p>\nThe 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.More repair cases about BMW,please check here: BMW Trouble Repair<\/p>\n

\nFailure of the power-assisted steering may be caused by various software-related issues.
\nThe following codes may be stored in the fault memory of the Electric Power Steering (EPS):<\/p>\n
\nScenario 2: 0x4823CB\/0x4823CC
\nScenario 3: 0x4823D2 and\/or 0x4823EC
\nScenario 4: 0x48239C (DSC warning lamp lights up in the instrument cluster)
\nScenario 5: No communication with the EPS is possible (not accessible using diagnostics)
\nScenario 6: 0x4823EE and 0x4823C2<\/p>\n
\nProgram the vehicle with ISTA\/P 2.51.2 (target I-Level F020-13-11-502), or a more recent version.<\/p>\n
\nProgram the vehicle with ISTA\/P 2.52.0 (target I-Level F020-14-03-502), or a more recent version.<\/p>\n
\nProgram the vehicle with ISTA\/P 2.51.2 (target I-Level F020-13-11-502), or a more recent version.<\/p>\n
\nFor 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.<\/p>\n
\nThe 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.<\/p>\n
\nPerform the \u201cStarting Steering\u201d 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.<\/p>\n
