BMW has released Service Information Bulletin (SIB) 12 14 25, Revision 02, to address a software issue affecting the Electric Drive Unit (eDrive motor) in certain 2022-2024 BMW i4 vehicles. This bulletin supersedes the previous SI B12 14 25 dated November 2025. The service action aims to prevent potential BMW i4 axle shaft damage caused by specific driving conditions.
Symptoms
Owners of affected 2022-2024 BMW i4 vehicles may experience a loss of traction or wheel slip in certain driving situations. This can be followed by a throttle or torque requirement that could potentially damage the axle shafts, ultimately leading to a broken drive shaft. This condition directly relates to the potential for BMW i4 axle shaft damage.
Cause
The root cause of this issue is identified as unfavorable software within the Electric Drive Unit (eDrive motor). This software can lead to the conditions described, increasing the risk of BMW i4 axle shaft damage.
Repair Procedure Summary
The correction for this service action involves programming the Electric Drive Unit (eDrive motor) with updated software. The procedure requires technicians to first determine the vehicle's current I-level using either AIR or the Key Reader/Aftersales Workplace (AWP) application.
The software update can be performed via Remote Software Upgrade (RSU) or ISTA programming. The required I-level for the update is S18A-25-11-530 or later. Remote Software Update is the preferred method, and instructions for this process are detailed in Service Information Bulletin SI B09 01 25. If RSU is not available for a particular vehicle, the software update must be performed using ISTA, with the required I-level S18A-25-11-530 or higher, available from ISTA 4.56.3x, planned from November 11, 2025.
