2025 BMW Models Secure Element Failure SIB 61 01 26

BMW has released Service Information Bulletin (SIB) 61 01 26 to address a condition described as a "Secure Element Failure" that can occur during engine start-up in various 2025 BMW models. This failure in the Basic Central Platform (BCP) can lead to communication errors and trigger a specific Check Control message on the instrument cluster.

This repair is categorized as both mobile-friendly and remote software upgrade (RSU) friendly, indicating flexibility in how the update can be performed.

Symptoms

Owners of affected 2025 BMW models may experience communication errors during vehicle start-up due to the "Secure Element Failure". The primary owner-facing symptom is the appearance of the Check Control message "Drive carefully. Driving stabilisation." on the instrument cluster. This message will typically appear within 40 seconds of the engine starting.

Fault Codes / DTCs

In addition to the warning message, the following fault memory entries may be stored in the vehicle's system:

• ACSM: 02010A - Coding: Coding data not qualified
• VIP: 02390A - VIP control unit: Coding data not released, signature
• IB: 02290A - DSC control unit: Coding data not released, signature
• HKFM: 020D0A - HKFM: Coding data are not qualified

Cause

The root cause of this "Secure Element Failure" and the associated communication errors is identified as software errors within the Basic Central Platform (BCP).

Important Warnings

BMW explicitly states that a parts replacement will not resolve this issue. The problem is purely software-related and requires programming. During any programming procedure, it is critical to always connect a BMW-approved battery charger/power supply, as outlined in SI B04 23 10, to maintain stable voltage.

If the vehicle's current I-level is not lower than the specified target integration level, no further action is required, and technicians should not program the vehicle but continue diagnosis with ISTA.

Repair Procedure Summary

To correct the "Secure Element Failure", BMW SIB 61 01 26 outlines a software update procedure. Technicians will first determine the vehicle's current I-level using applications like AIR or the Key Reader/AWP. If the current I-level is at or below the following target integration levels, the repair proceeds:

• G05, G06, G07: S18A-25-11-550 or lower
• G45: G045-25-11-551 or lower
• G60, G70: G070-25-11-550 or lower
• I20: I020-25-11-550 or lower
• F74, U10, U11: U006-25-11-550 or lower

If the vehicle qualifies, it will then be programmed using ISTA 4.58.1x or higher (expected release February 18, 2026) to update the Basic Central Platform. The target integration levels after programming should be:

• G05, G06, G07: S18A-26-03-519 or higher
• G45: G045-26-03-519 or higher
• G60, G70: G070-26-03-519 or higher
• I20: I020-26-03-519 or higher
• F74, U10, U11: U006-26-03-519 or higher

After programming, a vehicle test must be performed, and any stored fault memory entries should be deleted. ISTA will automatically reprogram and code all programmable control modules that do not have the latest software.

Required Tools or Parts

The primary tool required for this repair is the ISTA diagnostic software, specifically version 4.58.1x or higher. Additionally, a BMW-approved battery charger/power supply is essential to maintain vehicle voltage during the programming process. No parts replacement is necessary for this software-related issue.

Owner Action

If you own a 2025 BMW model listed and experience the "Drive carefully. Driving stabilisation." message or suspect a "Secure Element Failure", you should contact your authorized BMW dealership. Since this repair is RSU-friendly, it may be possible to perform the update remotely, but your dealer will confirm the best course of action. This software update is covered under warranty for eligible vehicles, and a parts replacement is not required.
