2025 BMW X5 X6 X7 Air Suspension Line Issue

Important Warnings

BMW has issued a critical advisory regarding vehicles affected by this delivery stop. It states: "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."

Symptoms

Owners of affected vehicles may experience a fault where "residual pressure is maintained in the struts and corresponding check control message." This indicates an issue with the air suspension system's proper function, potentially affecting ride height and comfort. The underlying cause for this symptom in the 2025 BMW X5 air suspension, as well as the X6 and X7, is an assembly error.

Cause

The root cause of this issue is an assembly error during the installation of the air system. Specifically, the air line on the air suspension supply system may not have been properly installed at the factory.

Repair Procedure Summary

Service Information Bulletin SIB 37 02 25 outlines the necessary steps to correct the improperly installed air lines. The procedure involves checking the air line installation position and re-installing them as needed.

Technicians will first need to remove the left side underbody protection, following repair procedure REP 51 71 017. After gaining access, they will check the air lines on the air supply system. The bulletin includes visual aids demonstrating correctly and incorrectly seated air lines. An improperly seated line is labeled as "NOK" (Not OK), while a correctly seated line is labeled "OK." If the air lines are found to be improperly seated, they will be fitted into the correct position to ensure proper function of the 2025 BMW X5 air suspension system and other affected models.

Required Tools or Parts

No specific parts are required for this repair, as the issue involves re-positioning existing components rather than replacing them.

Owner Action

This is primarily a delivery stop, meaning vehicles are inspected and repaired by the dealership before being delivered to customers. If you own a 2025 BMW X5, X6, or X7 that was produced on March 23rd, 24th, or April 4, 2025, and has already been delivered, BMW advises that the procedure will be performed the next time your vehicle is in the shop for service, provided the campaign has a remedy available status. BMW is not notifying consumers directly for this specific issue, so owners should check with their dealer or through BMW's online systems if they are concerned their vehicle might be affected by SIB 37 02 25.
