2025 BMW 2, 3, 4 Series Delivery Stop: Brake Fluid Tank

BMW has announced a Delivery Stop, identified as Service Information Bulletin (SIB) 34 02 25, concerning the brake fluid expansion tank in certain 2025 BMW models. This action, effective March 6, 2025, impacts vehicles produced between October 16, 2024, and February 7, 2025. The purpose of a Delivery Stop is to prevent the sale or delivery of potentially affected vehicles until a necessary repair or inspection has been completed.

The brake fluid expansion tank is a critical component of a vehicle's hydraulic braking system. It holds reserve brake fluid and allows for expansion and contraction of the fluid as temperatures change and brake pads wear. A fault with this component could potentially compromise braking performance, making this Delivery Stop a significant safety measure for the affected 2025 BMW 430i and other models.

What is a Delivery Stop?

A Delivery Stop is a proactive measure taken by a manufacturer to address a potential issue in vehicles that have not yet been delivered to customers. Unlike a recall, which typically applies to vehicles already on the road, a Delivery Stop targets vehicles in transit, at dealerships, or in inventory. This ensures that any identified problems are rectified before the vehicle reaches its owner, maintaining safety and quality standards from the outset. For dealers, it means that affected vehicles cannot be sold or delivered until the specified repair or inspection is completed.

Important Warnings for Dealers and Customers

BMW has issued strict directives regarding vehicles subject to this Delivery Stop. These warnings are crucial for ensuring safety and compliance:

• "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 2025 BMW 430i or other affected model currently in dealer inventory cannot be sold or delivered to a customer until the necessary inspection and repair related to the brake fluid expansion tank issue are completed. This also extends to replacement parts that might be affected by the same issue.

How to Check Your Vehicle's Status

For dealers, vehicles requiring this campaign will show an "Open" status when checked in systems such as AIR (Aftersales Information Research), AWP (Aftersales Workshop Portal), Campaign Summary, or Warranty Vehicle Inquiry. As of March 7, 2025, a list of affected vehicles is available in Inventory Campaign Details (ICD) under ROSS (Retailer Operating System). Dealers are advised to check their inventory as soon as possible.

Next Steps for Owners

If you have ordered a new 2025 BMW 430i or another model listed and are awaiting delivery, your dealership will be aware of this Delivery Stop. They are obligated to ensure that any required repairs are performed before your vehicle is released. There is no immediate action required from prospective owners other than to communicate with their dealership regarding the status of their vehicle. BMW states that the bulletin will be updated when additional information becomes available, suggesting that detailed repair procedures or further specifics may be released in due course.
