2024 BMW Integrated Braking System Programming Update

Important Warnings

BMW has designated this as a "DELIVERY STOP," meaning that affected vehicles cannot be delivered to customers until this update is completed. For vehicles already delivered, the procedure should be performed during the next service visit if the campaign status is "Open" and a remedy is available. Owners should note that no direct notification is being sent for this update; checking with a dealer is necessary.

This Service Information Bulletin (SIB 34 03 24) also includes the note "THIS REPAIR IS MOBILE FRIENDLY", indicating its suitability for mobile service operations.

Overview of the Issue

BMW has identified a need for improved diagnostic software within the Integrated Braking System (IB) control unit for a range of 2024 models. This update, detailed in Service Information Bulletin SIB 34 03 24, is a proactive measure to enhance the system's performance and diagnostic capabilities, ensuring optimal brake system functionality.

This bulletin, dated October 10, 2024, is Revision 1 and supersedes the previous SI B34 03 24 issued in September 2024. The update includes additional models not covered in the prior version.

Diagnosis and Campaign Status

Vehicles requiring this software update will show their campaign status as "Open" when checked through BMW's internal systems such as AIR, AWP, Campaign Summary, or Warranty Vehicle Inquiry. Dealers are advised to check their inventory for affected vehicles using Inventory Campaign Details (ICD) under ROSS.

Repair Procedure Summary

The correction involves programming the Integrated Braking System (IB) control unit with updated software. The procedure requires technicians to determine the vehicle's current I-level using BMW's diagnostic applications (AIR or AWP). The vehicle must then be programmed to a specific target integration level, depending on the model:

• G05, G07, G09 models: Target Integration level S18A-24-03-540 or higher.
• G60, G70 models: Target Integration level G070-24-03-542 or higher.
• U11 models: Target Integration level U006-24-03-540 or higher.

During the programming process, technicians must connect a BMW-approved battery charger/power supply, as referenced in SI B04 23 10, and use the ISTA 4 programming system. After programming, a vehicle test is performed, any fault memory is cleared, and the system's functionality is verified. The ISTA system automatically reprograms and codes all programmable control modules that do not have the latest software.

Required Tools and Software

To perform the BMW Integrated Braking System programming, technicians will use:

• ISTA 4.46.4x: This is the specific version of the diagnostic and programming software required for the update, released in early April 2024.
• ISTA 4: The general programming system.
• BMW-approved battery charger/power supply: Essential to maintain stable voltage during the programming process (refer to SI B04 23 10).

Warranty and Claim Information

Reimbursement for this action is processed via normal claim entry using specific work package information. The repair code for this service is 0034710200, identified as "Gx U11 Program control units (integrated braking system)".

Flat rate labor operation codes include:

• 00 77 545: For programming and encoding the vehicle control units, including a vehicle test (00 00 556/61 21 528), when completed before first vehicle delivery or as a standalone workshop visit.
• 00 77 546: For programming and encoding performed in conjunction with another campaign or repair during the same workshop visit.
• 00 77 030: For programming and encoding the vehicle control units, including a vehicle test (00 00 006/61 21 528), when the vehicle is already at the dealer and this action is open, with no other main work.
• 00 77 031: For programming and encoding performed in conjunction with another campaign or repair when the vehicle is already at the dealer, with no other main work.

If multiple programming and encoding technical campaign repairs are open, the procedure should be performed and invoiced only once. Technicians must also perform any additional before and/or after work required by other open campaigns on the vehicle.

What Owners Should Do

If you own a 2024 BMW model listed as affected, particularly if it was produced between late 2023 and early 2024, it is recommended to contact your authorized BMW dealer. Inquire about Service Information Bulletin SIB 34 03 24 and the status of the BMW Integrated Braking System programming update for your specific vehicle. Since this is a delivery stop, new vehicles will have the update performed before delivery. For vehicles already in customer hands, the update will be performed during a subsequent service visit if the campaign is active for your VIN.
