2024-2026 BMW Voice Assistant Call Issue SIB 65 22 25

Owners of 2024-2026 BMW X1, X2, and X3 models may experience a BMW voice assistant call issue where the Intelligent Personal Assistant (IPA) does not function correctly when attempting to initiate phone calls. This problem is detailed in BMW Service Information Bulletin (SIB) 65 22 25, which outlines the symptoms, cause, and the necessary repair to restore proper functionality.

Symptoms

The primary symptom of this issue is the BMW Intelligent Personal Assistant (IPA) malfunctioning during phone call initiation. Owners may find that when they ask the IPA to call a specific contact, "either another contact is dialed, or the IPA cannot locate the requested contact." This can lead to frustration and hinder the safe use of the hands-free calling system. The overarching issue is described as "UNABLE TO MAKE CALLS USING BMW VOICE ASSISTANT - HU-H6".

Affected Models and Cause

This BMW voice assistant call issue affects various BMW models equipped with the HU-H6 head unit, including the 2 Series Coupe (F74), X3 Sports Activity Vehicle (G45), X2 Sports Activity Coupe (U10), and X1 Sports Activity Vehicle (U11) from model years 2024-2026. The root cause has been identified as unfavorable software within the Headunit 6 (HU-H6) control module.

Repair Procedure Summary

To address the BMW voice assistant call issue, BMW dealerships will perform a software update on the vehicle's HU-H6 head unit. The procedure involves several key steps:

1. I-level Determination: Technicians first determine the vehicle's current I-level (integrated software level) using BMW's diagnostic tools like AIR or the Key Reader/AWP applications.
2. Software Update Condition: If the vehicle's I-level is already ...25-07-530 or higher, this Service Information Bulletin does not apply, and further diagnosis for other potential issues would be conducted. However, if the I-level is lower than ...25-07-530, the software update is required.
3. Programming: The vehicle will be programmed to I-level ...25-07-530 or higher using ISTA 4.54.4x diagnostic software, or a newer version, which was released on July 17, 2025.
4. Programming Steps: The programming process includes connecting a battery charger to maintain stable voltage, connecting the programming system (ISTA 4) to the vehicle, determining and accepting a "measures plan," which outlines the control units to be programmed, encoded, and enabled.
5. Post-Programming: After the programming is complete, technicians will follow a rework list, carry out a vehicle test, and clear any stored fault memory if necessary to ensure full functionality of the system.

Important Warnings

During the programming process, it is crucial to "Always connect a BMW-approved battery charger/power supply (SI B04 23 10)." This ensures that the vehicle's electrical system maintains a stable voltage throughout the software update, preventing potential issues or damage to control modules. Additionally, the ISTA system will automatically reprogram and code all programmable control modules that do not have the latest software during this process.

Required Tools and Parts

The primary tool required for this repair is the BMW ISTA diagnostic and programming system, specifically version 4.54.4x or higher. Technicians must also use a BMW-approved battery charger/power supply to maintain vehicle voltage during the software update. The repair is identified by Repair Code 6512580200, labeled "Headunit High HU-H Software error / internal device fault." Labor operations associated with this repair include 00 00 006, 00 00 556, 61 21 528, and 61 00 730, among others, depending on the specific diagnostic and vehicle test requirements.
