2024 BMW X1, X2 SiriusXM Malfunction SIB 65 24 24

Symptoms of SiriusXM Malfunction

Owners of 2024 BMW X1 (U11) and X2 (U10) models equipped with the HU-H6 head unit may experience issues with their SiriusXM satellite radio. The primary symptom of this BMW X1 SiriusXM malfunction is that SiriusXM may not be available or operating at all within the vehicle. In other cases, SiriusXM audio might be interrupted sporadically, leading to a frustrating listening experience.

Fault Codes / DTCs

When this SiriusXM malfunction occurs, specific fault codes may be stored in the vehicle's head unit (HU-H6). Technicians can diagnose the issue by checking for these diagnostic trouble codes (DTCs):

Code	Description
B7F912	"Communication between SDARS application and RAM SXM module is not possible"
B7F924	"SDARS SXM360L function not available"

These codes indicate a communication problem or an unavailability of the SDARS (Satellite Digital Audio Radio Service) function within the head unit.

Cause of the Malfunction

The root cause identified for this BMW X1 SiriusXM malfunction is unfavorable software residing in the head unit (HU-H6). This software prevents the SiriusXM system from operating correctly, leading to the symptoms and fault codes described.

Repair Procedure Summary

To correct the SiriusXM malfunction, BMW Service Information Bulletin SIB 65 24 24 outlines a procedure involving the programming of the HU-H6 head unit. The repair process is as follows:

1. I-Level Verification: A technician will first determine the vehicle's current I-Level (Integration Level) using BMW's AIR or AWP (Aftersales Workplace) applications.
2. Programming Decision:
   • If the vehicle's I-Level is already at U006-24-07-540 or a more recent version, programming is not required for this specific issue, and standard diagnosis for other potential problems will continue.
   • If the I-Level is lower than U006-24-07-540, the head unit will be programmed.
3. Programming the Head Unit: The vehicle will be programmed to I-Level U006-24-07-540 or higher, utilizing ISTA 4.48.4x (released August 12, 2024) or a newer version of the software. Key steps during programming include:
   • Connecting a BMW-approved battery charger/power supply to maintain stable voltage.
   • Connecting the programming system (ISTA 4) to the vehicle.
   • Allowing the system to determine and implement the necessary measures plan.
   • Accepting and fully working through the measures plan to program, encode, and enable the control units.
   • Following any specific rework list instructions.
   • After programming, performing a vehicle test and deleting any stored fault memory if needed.
4. Functionality Check: Once programming is complete, the technician will verify the full functionality of the SiriusXM system.

BMW notes that ISTA will automatically reprogram and code all programmable control modules that do not have the latest software during this process. The repair code associated with this service is 6512580200, labeled as "Headunit High HU-H Software error / internal device fault."

Important Warnings for Owners

• Battery Charger Requirement: During any programming procedure, it is crucial to always connect a BMW-approved battery charger/power supply. This ensures stable voltage and prevents potential issues during the software update. Refer to SI B04 23 10 for details on battery charger usage.
• Dealer Notification: While this is a manufacturer communication, owners experiencing the described symptoms should contact their authorized BMW dealer for diagnosis and repair.

Owner Action

If you own a 2024 BMW X1 or X2 and are experiencing SiriusXM issues such as no operation or sporadic audio interruptions, you should schedule an appointment with an authorized BMW dealership. Inform them of the symptoms you are observing. The dealership technicians are equipped to diagnose the issue, verify the vehicle's software I-Level, and perform the necessary head unit programming as outlined in SIB 65 24 24. This repair addresses the software-related BMW X1 SiriusXM malfunction and should restore proper SiriusXM functionality.
