2023 BMW X7 Electric Rear Sunshade Malfunction SIB 51 12 24

Owners of the 2023 BMW X7 Sports Activity Vehicle (G07 chassis) may encounter issues with the electric rear sunshades. BMW has released Service Information Bulletin (SIB) 51 12 24 to address situations where the BMW X7 electric sunshade in the rear door does not function correctly or appears wavy. This bulletin provides diagnostic and repair procedures for these specific problems.

Symptoms

Owners may observe one or both of the following conditions with their 2023 BMW X7 electric sunshade:

• "The electric sunshade in the rear door does not function or sticks upon operation"
• "The electric sunshade is wavy."

These symptoms can affect the rear left, right, or both sunshades, which are identified by Affected Option Code 417 - Rear Electric Window Shades.

Causes

BMW has identified two primary causes for these sunshade malfunctions:

• Sunshade does not function: This is typically caused by the sunshade cable popping out of its designated channel.
• Sunshade material issue: This can lead to the sunshade appearing wavy.

Repair Codes

When addressing these issues, BMW technicians will use specific repair codes for warranty claims:

• 5146052900: "Roller sun blind / curtain, rear door window Sticking/jammed"
• 5146053600: "Roller sun blind / curtain, rear door window Dented/wavy"

Repair Procedure Summary

The repair procedure outlined in SIB 51 12 24 depends on the specific cause of the BMW X7 electric sunshade issue. For sunshades that are not functioning, the steps involve:

1. Removal: The sunshade must be removed from the vehicle following repair instructions found in ISTA/AIR (Service Instruction 51 16 405).
2. Inspection: The sunshade cable is inspected for any damage. If the cable is damaged, the sunshade unit needs to be replaced.
3. Rework: If the cable is not damaged, it is reworked back into its channel. An attachment to the bulletin provides visual guidance for this step.
4. Reinstallation: The sunshade is reinstalled, and its operation is verified.

If the sunshade material is wavy, the entire sunshade unit must be replaced.

Required Parts

When replacement parts are needed, technicians will refer to the Electronic Parts Catalog (ETK) or AIR using the vehicle's chassis number to confirm the correct part numbers. The primary parts involved are:

• Roller sunblind electrical left
• Roller sunblind electrical right

Additional materials such as fluids, lubricants, one-time use screws, nuts, and seals may also be required and are to be replaced or installed according to ISTA repair instructions.

Warranty Information

Repairs performed under SIB 51 12 24 are covered under the terms of the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks. Technicians will use specific labor operation codes for diagnosis and repair to ensure proper claim processing. For example, labor operation 51 99 000 is used for reworking the cable to the channel.
