Important Warnings and Owner Information

Owners and technicians should be aware of the following critical points regarding this service action:

• Software Installation Check: It is crucial to check whether the customer has already downloaded the required Remote Software Update (RSU) into the vehicle but has "NOT YET installed it." This scenario requires programming via RSU as described in the procedure.
• Existing Software Level: If the vehicle's current I-level is already at 1020-24-11-540 or a more recent version, technicians should "Do not program the vehicle" and instead continue with standard diagnosis.
• Power Supply: During any programming or encoding procedure, technicians must "Always connect a BMW-approved battery charger/power supply (SI B04 23 10)" to ensure stable voltage.
• RSU Availability: If the RSU software update is not available in the vehicle or is lower than version 11.2024/40, the vehicle's software will need to be updated via ISTA (Integrated Service Technical Application).
• Control Module Failures: If one or more control modules fail during the reprogramming procedure, technicians must claim the required consequential repair work procedures to address this issue.
• Claim Submission: Only one of the flat rate labor operation codes listed can be used for claim submission/reimbursement purposes per workshop visit.

Repair Procedure Summary

The correction for the 2024 BMW iX Personal eSIM malfunction involves programming the complete vehicle. The preferred method for this Service Action, SIB 65 37 24, is a Remote Software Update (RSU).

1. Determine Current Software Level: Technicians will first determine the vehicle's current I-level using applications like AIR or AWP.
2. Remote Software Update (RSU): The vehicle needs to be updated to RSU software version 11.2024/40 or higher. This RSU software version is equivalent to I-Level 1020-24-11-540. The RSU process is initiated through the System Settings vehicle app by selecting Remote Software Upgrade. If the RSU software version to be installed is 11/2024.40 or higher, the RSU installation proceeds. This process typically takes about 30 minutes, after which the software version must be verified.
3. Programming via ISTA: If the RSU software is not currently downloaded in the vehicle, or if the available RSU software is lower than version 11.2024/40, the vehicle's software must be updated to I-level 1020-24-11-540 or higher using ISTA 4.50.4x. This involves connecting a battery charger and the programming system, determining a measures plan, and executing the programming and encoding of control units.

After the programming is complete, the functionality of the Personal eSIM system is checked to ensure the 2024 BMW iX Personal eSIM malfunction is resolved.

Required Tools or Parts

For the software update procedure, a BMW-approved battery charger/power supply (referenced as SI B04 23 10) is required to maintain stable voltage during programming.
