2024 BMW X5 RSU Comfort Access Faults

After performing a BMW Remote Software Upgrade (RSU), owners of certain 2024 BMW models, including the 2024 BMW X5, may notice reduced functionality in their vehicle's Comfort Access and Passive Go/Exit features. This issue is detailed in BMW Service Information Bulletin SIB 61 11 24, which outlines the cause and correction for these problems.

Symptoms

If your vehicle has experienced a 2024 BMW X5 RSU fault, you might observe that the Comfort Access and Passive Go/Exit features do not work as expected. This reduction in functionality is typically accompanied by specific error memory entries stored in the Basic Central Platform (BCP) module.

Fault Codes / DTCs

The following error memory entries may be stored in the Basic Central Platform (BCP) module, indicating a programming defect in the remote control receivers (FBD5):

Code	Description
80424A	Remote control receiver at the front (FBD5 VM): Programming defective
80424B	Remote control receiver at the rear (FBD5 HM): Programming defective
80424C	Remote control receiver at the front left (FBD5s VL): Programming defective
80424D	Remote control receiver at the front right (FBD5s VR): Programming defective
80424E	Remote control receiver at the rear right (FBD5s HR): Programming defective
80424F	Remote control receiver at the rear left (FBD5s HL): Programming defective

Cause

The root cause of this 2024 BMW X5 RSU fault is attributed to unfavorable fault setting conditions for one or more receivers of the radio remote control, specifically the FBD 5 aerial (also known as the antenna). This condition arises after a Remote Software Upgrade, leading to the programming defects identified by the fault codes.

Important Warnings

Owners should be aware of specific conditions related to this bulletin:

• "When the fault codes above are stored but not currently present, they can be ignored and deleted. The procedure below does not apply."
• "Note: Make sure that no telephone is connected to the vehicle during programming."
• "Part replacement will not provide a solution."

Correction

To resolve the issue, the remote-control receivers (FBD5) must be programmed and paired using the ISTA Service functions. This process ensures that the FBD5 aerial components are correctly configured after the Remote Software Upgrade.

Repair Procedure Summary

For vehicles exhibiting the fault codes, the repair procedure involves several steps using the ISTA diagnostic system:

1. Initiate Programming and Pairing: Technicians will use the service function, "ABL Initialize remote control receiver (ultra-wideband) and program it," found within ISTA under Vehicle Management > Service functions > Body > Locking and security functions > Remote control, key > Remote control receiver (UWB).
2. Program Receiver: The test plan will be opened, and the option to "Programming remote control receiver" will be selected.
3. Start Programming: The programming process is initiated by selecting "Program all (recommended)". It is crucial that no telephone is connected to the vehicle during this step, which can take up to 30 minutes.
4. Return to Selections: After successful programming, the technician will return to the "Teach in and program" selections window.
5. Pair Receivers: The next step is to select "Pairing the remote-control receivers."
6. Verify Pairing: All receiver statuses must show "pairing successful" to confirm the process is complete.
7. Clear Faults and Verify Functionality: Finally, any remaining fault codes are cleared, and the FBD5 receiver faults are confirmed not to have reoccurred. The Comfort Access and Passive Go/Exit features are then tested to ensure they are working as designed.

Required Tools or Parts

The primary tool required for this correction is the ISTA diagnostic system, which provides the necessary service functions for programming and pairing the remote-control receivers. No physical part replacement is needed, as the issue is software-related.
