2022-2023 BMW iX Head Unit Software Conflict Service Action

BMW has identified a potential issue with the head unit software in certain 2022-2023 BMW iX vehicles. This has led to the release of Service Information Bulletin SIB 65 29 23, a service action aimed at resolving conflicts in the head unit software that can cause operational problems.

This service action ensures that the head unit receives the necessary updates, preventing potential operational issues that may arise from conflicting software versions within the vehicle. This repair, identified by Repair Code 0065360400, is eligible for performance via Mobile Assistance for qualifying service centers, offering convenience for owners.

Symptoms

Owners of affected 2022-2023 BMW iX vehicles may experience various operational issues. These problems stem from the head unit not being properly updated along with the rest of the vehicle during a Remote Software Upgrade (RSU) campaign, leading to software conflicts. The specific symptoms can vary but generally relate to the functionality of the vehicle's infotainment and control systems, all caused by the BMW iX head unit software conflict.

Cause

The root cause of these operational issues is a conflict between the head unit software and other vehicle software. This conflict occurs when the head unit fails to update correctly alongside the rest of the vehicle during an RSU campaign.

Correction

The prescribed correction for this issue is to program the head unit to ensure software compatibility and resolve any existing conflicts.

Repair Procedure Summary

To correct the BMW iX head unit software conflict, technicians will program the vehicle's head unit. The process involves several key steps:

1. Determine Current Software Level: The technician will first determine the vehicle's current I-level using applications like AIR (Aftersales Information Research) or Key Reader AWP (Aftersales Workplace) applications.
2. Software Update: The vehicle will then be programmed to I-level 1020-23-07-545 or higher. This update requires the use of ISTA (Integrated Service Technical Application) 4.43.2x or a newer version of the programming software, with a release date of September 5, 2023, or later.
3. Preparation: Before programming, a BMW-approved battery charger/power supply must be connected to the vehicle, as detailed in SIB 04 23 10. The programming system (ISTA 4) is then connected to the vehicle.
4. Programming Execution: The technician will determine and follow a measures plan. This involves accepting and fully working through the measures plan, ensuring all control units are programmed, encoded, and enabled. A specific rework list must also be followed.
5. Post-Programming Check: After the programming has been fully completed, a vehicle test is performed, and any fault memory is deleted if needed. ISTA automatically reprograms and codes all programmable control modules that do not have the latest software.

Important Warnings and Information for Owners

• Battery Charger Requirement: Technicians are strictly advised to "Always connect a BMW-approved battery charger/power supply (SIB 04 23 10)" during the programming procedure to prevent interruptions and ensure a successful update.
• Mobile Service Eligibility: This repair is designated as "THIS REPAIR IS MOBILE FRIENDLY", meaning it can be performed via Mobile Assistance for qualifying service centers.
• Claiming Multiple Campaigns: During a workshop visit, if multiple programming and encoding Technical Campaign repairs are open, the programming and encoding procedure may only be invoiced one time.
• Checking Vehicle Status: Vehicles requiring this campaign will show as “Open” when checked in systems like AIR, AWP, Campaign Summary, or Warranty Vehicle Inquiry.
