2024 BMW X3/X4 Delivery Stop: Wishbone Hexagon Nut

BMW has announced a delivery stop, identified by Service Information Bulletin (SIB) 31 05 24, affecting specific 2024 BMW X3 and X4 vehicles. This measure is in place to address an issue with the wishbone hexagon nut, which was not properly secured during manufacturing. The 2024 BMW X3 delivery stop is crucial for ensuring vehicle safety and performance before customer delivery.

This bulletin, SIB 31 05 24 (Revision 2), supersedes the previous SI B31 05 24 dated July 2024, indicating an update to the information provided to dealerships. The delivery stop became effective on July 12, 2024, for affected vehicles produced between April 26, 2024, and May 13, 2024.

Important Warnings for Owners and Dealerships

BMW has issued strict directives 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."

These warnings emphasize that no affected vehicle should be sold or delivered to a customer until the necessary repair is completed. Dealers must check their inventory for vehicles requiring this campaign, which will show as “Open” in BMW's internal systems.

Symptoms

Owners of affected vehicles might eventually notice "Metallic" noises. This symptom indicates a potential issue with the wishbone assembly, stemming from the improperly secured hexagon nut.

Cause of the Issue

The root cause of this delivery stop is that the wishbone was not secured to the swivel bearing according to manufacturing instructions. This oversight can lead to the nut loosening over time, resulting in the metallic noises reported.

Repair Procedure Summary

The correction for this issue involves replacing the affected hexagon nut on the swivel bearing. Technicians are instructed to refer to repair procedure REP31 12 001, which details the steps for replacing the left or right wishbone. The procedure includes removing the existing hexagon nut (1), replacing it with a new one, and then tightening the new nut to the specified torque. A counter-hold at the Torx socket is required during this process.

It is important to note that the specific side of the vehicle (left or right) requiring the hexagon nut replacement cannot be determined without further information. Dealerships will resolve this through a BMW/MINI Recall Parts IDS ticket, which will specify the side needing repair.

Required Parts

To perform the repair outlined in SIB 31 05 24, the following parts may be required:

• Hexagon nut with collar: Part Number 07 14 6 875 114
• Collar screw with spring: Part Number 31 20 6 866 022
• Combination nut: Part Number 33 30 6 787 062

These parts are essential for correctly securing the wishbone to the swivel bearing and resolving the potential for metallic noises. This ensures the 2024 BMW X3 delivery stop is addressed effectively.

Owner Action

If you own a 2024 BMW X3 or X4 that falls within the production dates of April 26, 2024, to May 13, 2024, and have not yet taken delivery, your vehicle is subject to this delivery stop. The repair will be completed by the dealership before you receive the vehicle.
