2025 BMW X5/X6/X7 Air Suspension Delivery Stop SIB 37 02 25

BMW has issued Service Information Bulletin (SIB) 37 02 25, a Delivery Stop, for a limited number of 2025 BMW X5, X6, and X7 vehicles. This bulletin, which is Revision 01 and replaces SI B37 02 25 dated May 2025, highlights a potential issue with the air suspension supply system lines.

The core problem is that the air lines may not have been properly installed during vehicle assembly. If this condition exists, it can lead to residual pressure being maintained in the suspension struts and trigger a "check control message" on the vehicle's dashboard.

Important Warnings

BMW has issued a critical advisory regarding vehicles subject to this Delivery Stop:

• "Do not deliver to a customer, a New, Certified Pre-Owned or Used vehicle subject to a Delivery Stop, until the vehicle is repaired."
• "Do not use or sell replacement equipment/parts subject to a Delivery Stop."

This means that any affected 2025 BMW X5, X6, or X7 vehicle cannot be sold or delivered to a customer until the necessary inspection and repair procedure outlined in SIB 37 02 25 has been completed. This also extends to any replacement parts that might be affected by the same issue.

Symptoms

If the air line on the air suspension supply system is not properly installed, owners may notice the following:

• A "check control message" appearing on the instrument cluster.
• Residual pressure being maintained in the suspension struts, which could affect ride quality or vehicle height.

These symptoms are a direct result of the improper installation of the air lines, impacting the functionality of the air suspension system in your BMW X5 air supply system.

Cause of the Issue

The root cause of this problem has been identified as an assembly error during the air system installation process. This indicates a manufacturing oversight rather than a component defect, leading to the air lines not being correctly seated within the air suspension supply system.

Repair Procedure Summary

The correction for this issue involves a straightforward inspection and potential re-installation of the air lines. Technicians will follow these steps:

1. Access: The left side underbody protection must be removed. This step is performed according to BMW's Repair Instruction (REP) 51 71 017, which details the process for removing and installing/replacing the left underbody protection.
2. Inspection: Technicians will then check the air lines on the air supply system to determine if they are properly seated.
3. Correction: If the air lines are found to be improperly installed, they will be fitted into the correct position. No parts are required for this repair, as it involves re-seating existing components.

The repair code for this action is 0037360100. BMW has provided specific labor operation codes for different scenarios, including checking without rework (00 78 663 or 00 78 133) and checking with rework (00 78 664 or 00 79 134), with varying labor allowances.

Owner Action / Next Steps

If you own a 2025 BMW X5, X6, or X7 produced on April 4, 2025, and have not yet taken delivery, your vehicle will be repaired by the dealership before you receive it. If you have already taken delivery of an affected vehicle, this procedure should be performed during your next service visit. BMW is not explicitly notifying consumers for this specific Delivery Stop; rather, it is managed at the dealer level for pre-delivery vehicles and during routine service for already delivered ones. You can contact your authorized BMW dealer to inquire if your vehicle is affected by SIB 37 02 25 and to schedule an inspection if necessary. This will ensure the proper functioning of your BMW X5 air supply system.
