2024-2026 BMW Automatic Hold Function Lost TSB

BMW has issued Service Information Bulletin (SIB) 34 08 25 to address a concern where the BMW Automatic Hold function lost its setting after the vehicle is switched off. This issue, which can affect various 2024-2026 BMW models, requires drivers to manually reactivate the Automatic Hold function at the start of each journey. This bulletin provides a software-based solution to ensure the function retains its setting.

Symptoms

Owners of affected BMW vehicles may observe the following:

• The "Automatic Hold function is not automatically stored" for the next journey.
• The driver must activate the Automatic Hold function at the beginning of every trip.
• This behavior may occur more frequently after a software update to I-level 25-03-500 or higher.

Cause of the Issue

The problem arises because stored data related to the Automatic Hold function is lost during a "terminal change" (when the vehicle is switched off). This data loss specifically occurs if the Automatic Hold function was active and a personal driver profile has been selected at the same time. This indicates a software error within the vehicle's control systems.

Important Warnings and Owner Information

BMW SIB 34 08 25 includes critical advisories for technicians and owners:

• Do not program the vehicle if its current I-level is already at or above the specified target versions (e.g., 25-07-550 for G45 models, 25-07-551 for F74, F95, F96, G05, G06, G07, G09, U10, U11 models, or 25-07-538 for G60, G70, G90, G99 models). In such cases, standard diagnosis should be performed.
• Always connect a BMW-approved battery charger/power supply (SI B04 23 10) when performing programming to prevent voltage drops that could damage control units.
• A parts replacement does not provide a remedy for this issue and is therefore unnecessary. Owners should not be upsold on replacement parts for this specific problem.
• The BMW software solution is covered under the terms of the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks, or the BMW Certified Pre-Owned Program.

Repair Procedure Summary

The resolution for the BMW Automatic Hold function lost issue involves updating the vehicle's software. BMW dealerships will perform the following steps:

1. Determine Current I-level: Technicians will check the vehicle's current software integration level (I-level) using BMW's diagnostic applications, AIR or AWP (Aftersales Workplace).
2. Software Update: If the vehicle's I-level is lower than the required versions—specifically I-level 25-07-550 for G45 models, 25-07-551 for F74, F95, F96, G05, G06, G07, G09, U10, U11 models, or 25-07-538 for G60, G70, G90, G99 models—the vehicle will be programmed to the latest I-level.
3. Programming Process: The programming requires connecting a BMW-approved battery charger and the ISTA 4 programming system. ISTA will automatically reprogram and code all control modules that do not have the latest software.
4. Functionality Check: After programming, the technician will verify that the Automatic Hold function operates correctly and retains its setting after the vehicle is switched off.
