Owners of certain 2023-2026 BMW models may experience a situation where the vehicle's emergency call system activates without any apparent reason. This issue, described in BMW Service Information Bulletin (SIB) 84 06 25, means the BMW emergency call triggered erroneously, even when there is no customer interaction with the SOS button or an airbag deployment event. In some cases, the system may activate even when the vehicle is unoccupied.
Symptoms
The primary symptom is the BMW emergency call triggered erroneously. This means the vehicle's emergency call system activates unexpectedly. This can occur without the driver or passengers pressing the SOS Call button, and without an airbag deployment event. The system may even activate when no one is inside the vehicle.
Cause
The root cause of the emergency call system activating incorrectly is identified as unfavorable software within the telematics module, specifically the TCB4 unit. This software issue leads to the 'Telematics control unit Occasional failure'.
Correction
The correction for this issue involves programming the TCB4 telematics control unit. This software update aims to resolve the 'Telematics control unit Occasional failure' and prevent the BMW emergency call triggered erroneously.
Repair Procedure Summary
To address the erroneous emergency call triggers, technicians must perform a software update on the vehicle's TCB4 module. The procedure involves several key steps:
- I-level Check: The vehicle's current I-level (software integration level) is determined using BMW's AIR or Key Reader/AWP applications.
- Programming Decision:
- If the I-level is already at or above 25-07-500, no programming is needed for this issue; standard diagnosis should continue.
- If the I-level is lower than 25-07-500, the vehicle must be programmed to I-level 25-07-500 or higher.
- Software Update: The programming is performed using ISTA 4.54.3x, a software version released on July 22, 2025, or a newer version.
- Programming Steps: This includes connecting a battery charger, connecting the programming system (ISTA 4) to the vehicle, determining and accepting the measures plan, following a rework list, performing a vehicle test, and deleting any fault memory if necessary.
Important Warnings and Owner Information
- No Programming Needed if Up-to-Date: If your vehicle's software I-level is already at 25-07-500 or more recent, the programming outlined in SIB 84 06 25 is not required for this specific issue. Continuing with standard diagnosis is the appropriate next step.
- Battery Charger Requirement: During any programming, it is crucial to
