2024-2026 BMW X1/X2 Power Windows & Mirrors Not Functioning

BMW has issued Service Information Bulletin (SIB) 61 15 25 to address a software error affecting the power windows and exterior mirrors in certain 2024-2026 BMW X1, X2, and 2 Series Gran Coupe models. This bulletin, dated September 2, 2025, outlines a specific procedure for resolving the malfunction.

This repair is categorized as both mobile-friendly and Remote Software Upgrade (RSU) friendly, indicating flexibility in how the service can be performed.

Symptoms

Owners may notice that the power windows and exterior mirrors on either the driver's side or the passenger's side are not functioning. It's important to note that the fault will occur on only one side at a time, not simultaneously on both sides of the vehicle. If you're experiencing a BMW X1 power windows not working issue, this SIB may apply to your vehicle.

Cause

The root cause of this malfunction is identified as a software error within the TSG control module. This module, also known as the door control module, is responsible for operating the power windows and exterior mirrors. The internal device fault is specifically linked to this software anomaly.

Important Warnings

BMW explicitly states that a permanent software solution is currently under development. Until this permanent fix is released, technicians are advised:

• "DO NOT replace any parts as it does NOT provide a solution."

This means that replacing components like the TSG control module will not resolve the issue and should be avoided. This SIB will be updated once the permanent software solution becomes available.

Repair Procedure Summary

The recommended correction involves performing a reset of the TSG control module using BMW's integrated Service Technical Application (ISTA). The procedure for addressing the BMW X1 power windows not working or exterior mirrors issue includes several steps:

1. Verify the Concern: Confirm the customer's reported issue regarding the power windows and exterior mirrors.
2. Vehicle Preparation: Connect an approved BMW battery charger to the vehicle to maintain stable voltage during diagnostics.
3. Diagnostic Connection: Connect the vehicle to ISTA and perform a comprehensive vehicle short test.
4. Fault Code Reading: Read all stored fault codes from the vehicle's systems.
5. Module Check: Specifically check for fault codes stored in the TSGFA (driver side) and TSGBF (passenger side) control modules, which are directly related to the door functions.
6. Control Unit Reset: Using ISTA, navigate to 'Vehicle Information', then 'Control Unit Tree'. Select either 'TSGFA' or 'TSGBF', proceed to 'Control Unit Functions', then 'Component Actuation', and finally 'Perform a control unit reset'.
7. Verification and Clearing: After the reset, verify that the power windows and exterior mirrors are functioning correctly. Clear any remaining fault codes via ISTA.

No parts are required for this repair, as it is purely a software-related correction.
