2023 BMW X5 Wireless Charging Tray Service Action

BMW has released Service Information Bulletin (SIB) 81 04 24 to address issues with the wireless charging tray in certain 2023 BMW X5, X7, and Z4 vehicles. This service action aims to resolve problems affecting key vehicle functionalities.

Symptoms

Owners of affected vehicles may experience operational issues with their "Comfort Access or remote functions." This can manifest as difficulty locking/unlocking the vehicle using Comfort Access or problems with remote control features.

Cause

The root cause of these problems is identified as a firmware error within the Wireless Charging Tray. This error prevents the vehicle from entering its normal sleep mode consistently. After multiple failed attempts to enter sleep, the vehicle is forced to power down by switching off terminal 30f. This unintended power management directly deactivates the "Comfort Access or remote functions" that rely on the vehicle's active state.

Repair Procedure Summary

The recommended correction for this issue is to replace the Wireless Charging Tray. Technicians will follow specific repair instructions, identified as 84 10 120, titled “Removing and Installing Wireless Charging Storage.” These instructions are available through BMW's internal systems, AIR or ISTA, to ensure the replacement is performed correctly.

Required Parts

The primary part required for this service action is the Wireless Charging Tray itself. The specific part number to be used and invoiced is 84 10 5 A7F 847, described as a Storage Tray NFC/WCA. Additional materials and small parts, such as fluids, lubricants, one-time use screws, nuts, and seals, may also be required based on the specific vehicle type and ISTA repair instructions. These items should be selected from the Electronic Parts Catalog and invoiced separately under the Repair Code listed in this bulletin.

Claim Information

Reimbursement for this Service Action, SIB 81 04 24, will be processed through normal claim entry using the applicable work package information. The designated Repair Code for this procedure is 0084300200.

Important Warnings

BMW specifies that this service action must be completed before the first delivery of an affected vehicle to a customer. If the vehicle is already in the workshop, the repair should be performed immediately. This ensures that customers receive vehicles with fully functional "Comfort Access or remote functions" and prevents potential issues from arising after purchase.

Owner Action

If you own a 2023 BMW X5, X7, or Z4 and are experiencing issues with your "Comfort Access or remote functions," or if you wish to confirm if your vehicle is affected by Service Action SIB 81 04 24, you should contact your authorized BMW dealer. They can check if your vehicle requires this campaign and schedule the necessary repair, which involves replacing the wireless charging tray.
