2023 BMW X7 Transmission Heat Shield Delivery Stop

BMW has issued Service Information Bulletin SIB 41 08 22 concerning a delivery stop for certain 2023 BMW X7 Sports Activity Vehicles (SAV) due to an improperly installed transmission heat shield. This bulletin, identified as Revision 2, supersedes the previous bulletin SI B41 08 22 dated January 2023. The delivery stop affects vehicles produced between September 1, 2022, and December 3, 2022.

Important Warnings for Owners and Dealers

BMW has issued a critical advisory regarding 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 2023 BMW X7 vehicle cannot be sold or delivered to a customer until the inspection and necessary repair related to the transmission heat shield are completed.

Potential Issue

The core issue of this delivery stop, identified by BMW Service Information Bulletin SIB 41 08 22, is the mistaken installation of a heat shield above the transmission during vehicle assembly. BMW states: "No heat shield should have been installed. It may contact other components in the narrow space along the bottom of the transmission tunnel." While not explicitly stated as a symptom an owner would notice, the potential for contact with other components could lead to various issues if not addressed.

How to Check if Your Vehicle is Affected

Vehicles requiring this campaign to be completed will show an "Open" status when checked in BMW's internal systems such as AIR, AWP, Campaign Summary, or Warranty Vehicle Inquiry. Owners of a 2023 BMW X7 (G07) produced within the specified dates should contact their authorized BMW dealer to verify if their vehicle is subject to this delivery stop.

Repair Procedure Summary

The repair for the 2023 BMW X7 transmission heat shield issue involves a multi-step process for technicians:

1. Remove Underbody Protection Panel: The first step requires removing the underbody protection panel. Technicians will follow specific repair instructions detailed in AIR/ISTA document 51 47 491 for this procedure.
2. Inspect for Heat Shield: The transmission area is then inspected for the presence of the heat shield. If no heat shield is found, no further repairs are needed, and the vehicle can be reassembled. If the heat shield is present, the repair proceeds to the next step. Technicians are specifically advised that the corrugated aluminum cover (often marked with a red 'X' in diagrams) is not the component to check for.
3. Remove Transmission: If the heat shield is present, the transmission must be removed. This involves following repair instructions listed in AIR or ISTA 24 00 240, titled "Removing and installing automatic transmission."
4. Inspect for Damage: During transmission removal, technicians must closely inspect any electrical harnesses or fluid-carrying lines fastened to the underside of the transmission tunnel for damage that may have occurred due to contact with the heat shield. Any damaged components must be replaced.
5. Remove Heat Shield: The mistakenly installed heat shield is then removed and discarded.
6. Reassemble Vehicle: Finally, the vehicle is reassembled following the reverse order of disassembly.

Claim Information

Reimbursement for this action is handled via normal claim entry using applicable work packages. Various labor operation codes are available depending on whether only an inspection is performed or if the heat shield is found and removed. These codes include 00 73 798, 00 73 799, 00 73 215, and 00 73 216. The repair code for removing the heat shield is 0051580500. Sublet reimbursement for bulk materials may also be claimed, with reference to SI B01 29 16 for additional information.

Required Tools or Parts

For inspections where no repair is needed (Work Package 1 and 3), no specific parts are required. For procedures involving the removal and installation of the automatic transmission (Work Package 2 and 4), parts are specified by AIR/ISTA. No special tools beyond those typically used for transmission work are explicitly mentioned.
