2024 BMW X5/X6/X7/XM BCP Software Error SIB 61 28 24

BMW has released Service Information Bulletin (SIB) 61 28 24, Revision 1, to address a software anomaly affecting the Basic Central Platform (BCP) in certain 2024 BMW X5, X6, X7, and XM models. This bulletin supersedes the previous SI B61 28 24 dated November 2024. The core problem is a software error within the BCP that leads to incorrect storage of critical vehicle identifiers: the Calibration Identification Number (CAL ID) and the Calibration Verification Number (CVN).

These identifiers are essential for verifying official BMW software and are typically generated during each programming session. When they are not stored correctly, it can indicate an underlying software integrity issue within the BCP. This service action provides a clear procedure for dealers to update the vehicle's software, ensuring proper functionality and data integrity for the 2024 BMW X5 BCP software error.

Symptoms

The primary symptom of this issue is an internal software error within the Basic Central Platform (BCP). Owners may not directly observe a specific dashboard warning or operational fault related to the incorrect storage of the Calibration Identification Number (CAL ID) and Calibration Verification Number (CVN). However, these numbers are crucial for the vehicle's internal software management and verification processes.

Cause

The root cause of this problem is identified as software errors within the Basic Central Platform (BCP). These errors specifically interfere with the correct generation and storage of the Calibration Identification Number (CAL ID) and the Calibration Verification Number (CVN).

Repair Procedure Summary

The correction for the 2024 BMW X5 BCP software error involves programming and encoding the Basic Central Platform. BMW outlines a procedure that can be performed either via a Remote Software Update (RSU) or through dealer programming using the ISTA diagnostic system.

Dealer Programming via ISTA

1. Determine Current I-level: Technicians must first determine the vehicle's current integration level (I-level) using applications like AIR or the Key Reader/AWP (Aftersales Workplace).
2. Software Update Requirement: If the current vehicle integration level is S18A-24-07-535 or lower, the vehicle requires programming.
3. ISTA Programming: The vehicle will be programmed using ISTA version 4.49.2x or higher, which was released on September 5, 2024. The target integration level after programming will be S18A-24-07-540 or higher.
4. Post-Programming Steps: After programming, a vehicle test is performed, and any stored fault memory is deleted. ISTA automatically reprograms and codes all programmable control modules that do not have the latest software.
5. Battery Support: It is crucial to always connect a BMW-approved battery charger/power supply (as per SI B04 23 10) during the programming process to maintain stable voltage.

Remote Software Update (RSU)

Performing a Remote Software Update (RSU) is the preferred method to address this issue. The RSU process is detailed in SI B09 01 25 and can be initiated as follows:

1. Check RSU Availability: Owners or dealers can check for the available RSU offering via the vehicle's app or through the Dealer Cockpit via the S-Gate dealer portal or AWP. The available RSU offering can be checked in the vehicle app, or through Dealer Cockpit via the S-Gate dealer portal or AWP.
2. Initiate RSU: If the software version to be installed is S18A-24-07-540 (RSU version 07/2024.40) or higher, the RSU installation can be started directly in the vehicle. Follow the instructions presented in the Central Information Display (CID).
3. Verify Installation: Approximately 30 minutes after initiation, it's necessary to check in the vehicle to confirm the RSU installation was successful and that the I-level is S18A-24-07-540 or higher (RSU Installed version 07/2024.40). The CID may display "SOFTWARE INFO" with "The data will be downloaded automatically as soon as a new upgrade is available."
4. CID Navigation: To view RSU information in the CID, navigate to "System Settings" and then "Remote Software Upgrade." The RSU installed version will be displayed in the upper left corner of the CID.
5. Installation Best Practices: BMW recommends exiting and locking the vehicle during RSU installation. No device should be connected to the on-board diagnosis connector (e.g., ICOM). The vehicle does not require connectivity during the installation as the software is already downloaded, meaning it can be parked in an underground car park. If "Check Control messages (CCM)" are displayed after installation, allow the vehicle to go to sleep before rechecking the I-level.

Important Warnings

Owners should be aware that a parts replacement will not provide solution for this Basic Central Platform (BCP) software error. The issue is purely software-related and requires a software update, not hardware replacement.

Owner Action

If you own a 2024 BMW X5, X6, X7, or XM manufactured between July 28, 2023, and July 30, 2024, and are concerned about the 2024 BMW X5 BCP software error, you should contact your authorized BMW dealer. They can check if your vehicle is affected by this service action by verifying its status in BMW's internal systems. The repair involves a software update and is typically covered under warranty.

Your dealer will determine the most appropriate method for updating your vehicle's software, either through a Remote Software Update (RSU) if available for your vehicle, or via programming using the ISTA system. This update ensures that the Calibration Identification Number (CAL ID) and Calibration Verification Number (CVN) are correctly stored, maintaining the integrity of your vehicle's software.

Claim Information

Dealers will submit claims using specific labor operation codes. For programming and encoding the BCP, the repair code is 0061940800. Other relevant campaign numbers for claim submission include 00 00 006, 00 00 556, 61 21 528, and 61 00 730. Only one programming and encoding procedure can be invoiced per workshop visit.
