2025 BMW X/iX and Series Central Information Display Flickering TSB

BMW has released Service Information Bulletin SIB 65 35 24 (Revision 1) to address a common concern among owners of certain 2025 BMW X/iX and Series models. This bulletin specifically targets instances where the Central Information Display (CID) exhibits periodic flickering.

This bulletin replaces the previous version, SI B65 35 24 dated December 2024, indicating an updated procedure for resolving this issue. The core problem, a 2025 BMW CID flickering, is attributed to outdated software within the vehicle's head unit.

Symptoms

Owners may observe the Central Information Display (CID) side of the Multifunction Display flickering intermittently. This flickering is not constant but typically occurs once every 15 to 50 seconds. Despite this visual anomaly, the system usually does not store any fault memory entries related to this specific customer complaint.

Fault Codes / DTCs

While the initial symptom of a 2025 BMW CID flickering does not typically generate a fault code, technicians are advised to check for a specific fault after certain diagnostic steps. If the vehicle's I-level is already up-to-date, or if issues arise during programming, the fault code "B7F935 - HU: Internal fault (HDCP)" may be stored. If this code is present, technicians should follow the applicable test plan and recommendations to address it.

Diagnosis / Trigger Conditions

The diagnostic process for the 2025 BMW CID flickering involves determining the vehicle's current I-level. This can be done using BMW's diagnostic applications like AIR or the Key Reader/AWP (Aftersales Workplace).

• If the I-level is ...25-03-550 or a more recent version: The vehicle should not be programmed. Instead, technicians should check for the "B7F935 - HU: Internal fault (HDCP)" code and follow its specific test plan if found.
• If the I-level is lower than ...25-03-550: The head unit requires programming to I-level ...25-03-550 or higher. This update is performed using ISTA 4.53.2x, which was released on May 8, 2025, or a newer version.

Repair Procedure Summary

The primary correction for the 2025 BMW CID flickering is to program the head unit with the latest software. The procedure involves several key steps:

1. Connect Power Supply: A BMW-approved battery charger/power supply (as per SI B04 23 10) must be connected to the vehicle to maintain stable voltage during programming.
2. Connect Programming System: The programming system, ISTA 4, is connected to the vehicle.
3. Determine Measures Plan: The system will identify the necessary programming and encoding steps.
4. Execute Programming: The technician must accept and fully work through the measures plan, ensuring all control units are programmed, encoded, and enabled.
5. Follow Rework List: Any additional steps specified in the rework list must be completed.
6. Vehicle Test and Fault Memory Deletion: After programming, a vehicle test is performed, and any remaining fault memory is deleted.

This process ensures that all programmable control modules receive the latest software, resolving the underlying cause of the display flickering.

Important Warnings

• No Initial Fault Memory: Owners should be aware that the periodic flickering of the Central Information Display typically does not result in a stored fault code in the vehicle's memory.
• Battery Charger Requirement: For any programming or coding work, it is crucial to always connect a BMW-approved battery charger/power supply to prevent voltage drops that could damage control modules.
• Mobile Friendly Repair: This repair is designated as "MOBILE FRIENDLY," indicating it can potentially be performed by mobile service technicians.

Required Tools or Parts

Technicians will need access to specific BMW diagnostic and programming equipment:

• ISTA 4.53.2x or higher: This is the required software for programming the head unit.
• BMW-approved battery charger/power supply: Essential for maintaining stable voltage during the programming process.

Owner Action

If you are experiencing a 2025 BMW CID flickering, you should schedule an appointment with an authorized BMW service center. Inform them about the symptoms you are observing. The dealership technician will be able to diagnose the vehicle's I-level and perform the necessary head unit software update as described in SIB 65 35 24. This repair is typically covered under warranty.
