2022-2024 BMW iX Software Update for Connectivity Issues (SIB 65 11 24)

BMW has issued Service Information Bulletin (SIB) 65 11 24, a service action to implement quality improvements and robustness measures through a software update for 2022-2024 BMW iX vehicles. This bulletin, which is a revision of SI B65 11 24 dated May 2024, aims to resolve several common issues experienced by owners.

Symptoms

Owners of affected 2022-2024 BMW iX models may experience one or more of the following symptoms, which are addressed by this software update:

• Bluetooth malfunctions, leading to unreliable connectivity.
• A slower than expected start-up phase for the Head Unit (HU), affecting the operating system's responsiveness.
• Frequent disconnections from Apple CarPlay.
• Issues with vehicle access and achieving a drive-ready state.
• An AC charging abort error, preventing proper charging.
• Remote Control Parking functionality being inoperative.

These issues are attributed to unfavorable software in the vehicle, which the 2023 BMW iX manufacturer_communication aims to rectify.

Diagnosis / Trigger Conditions

Vehicles requiring this service action will be identified as "Open" in BMW's internal systems such as AIR, AWP, Campaign Summary, or Warranty Vehicle Inquiry. Dealers can also check the Inventory Campaign Details (ICD) under ROSS. The primary trigger for this update is the presence of older software versions in the vehicle.

Repair Procedure Summary

The correction involves programming the complete vehicle with an updated software version using either a Remote Software Update (RSU) or the ISTA diagnostic system. RSU is the preferred method for installation.

1. Determine Current Software Level: Technicians will first check the vehicle's current I-level using AIR or AWP applications.
2. Software Update via RSU: If the vehicle's current RSU software version is lower than 03.2024/40 or if an update is available but not yet installed, the RSU process will be initiated. This involves checking the available RSU version in the vehicle's System Settings app and then installing it through the Central Information Display. The target RSU software version is 03.2024/40 or higher.
3. Software Update via ISTA: If an RSU is not available or cannot be performed, the vehicle will be programmed using ISTA. The target I-level for ISTA programming is 1020-24-03-540 or higher, using ISTA 4.46.4x or newer. This process includes connecting a battery charger, connecting the programming system, determining and executing the measures plan, following a rework list, and performing a vehicle test with fault memory deletion after programming.
4. Functionality Check: After the programming is complete, the functionality of the affected systems will be verified.

Required Tools or Parts

To perform this service action, specific tools and software versions are required:

• RSU Software Version: 03.2024/40 or higher.
• I-Level: 1020-24-03-540 or higher.
• ISTA Version: ISTA 4.46.4x or higher (released April 4, 2024).
• BMW-approved Battery Charger/Power Supply: As specified in SIB 04 23 10.

Important Warnings

Owners should be aware of the following critical information:

• Battery Charger Requirement: Dealers are instructed to always connect a BMW-approved battery charger/power supply, as detailed in SIB 04 23 10, when performing programming or coding procedures. This is crucial to prevent issues during the update process.

Owner Action

If you own a 2022-2024 BMW iX and are experiencing any of the symptoms mentioned, such as Bluetooth malfunctions, Apple CarPlay disconnections, or issues with AC charging or Remote Control Parking, your vehicle may be eligible for this software update.
