2024-2025 BMW X3 / 5 Series Squeaking Exterior Mirror TSB

BMW has released Service Information Bulletin (SIB) SIB 51 02 24 to address a common complaint among owners of certain 2024-2025 BMW X3 and 5 Series vehicles: a BMW squeaking exterior mirror when folding in or out. This bulletin, dated January 7, 2025, is a revision of an earlier bulletin (SI B51 02 24 dated March 2024) and includes updated model applicability and claim information.

Symptoms

Owners may notice "A squeaking sound is heard when folding either of the exterior mirrors assemblies in or out." This sound occurs specifically when the mirrors are moving, either retracting or extending. A video (V51 02 24) is available to technicians to help identify the specific noise.

Cause

The root cause of the BMW squeaking exterior mirror issue is identified as "Unfavorable tolerance positions within the exterior mirror assembly." This means that minor variations in the manufacturing or assembly of the mirror components can lead to friction and noise during operation.

Repair Procedure Summary

BMW's recommended correction involves cleaning and lubricating the sliding surface of the exterior mirror assembly. This repair is designated as "MOBILE FRIENDLY," indicating it can be performed efficiently.

The procedure for addressing the BMW squeaking exterior mirror typically involves:

1. Verifying the customer's complaint to ensure the squeaking sound is present.
2. Manually folding the exterior mirror assembly inwards.
3. Thoroughly cleaning the sliding surface on the exterior mirror assembly and applying PF1 lubricant.
4. Manually folding the exterior mirror assembly outwards.
5. Cleaning the sliding surface again and applying PF1 lubricant.
6. If the squeaking sound persists after these steps, the affected exterior mirror assembly may need to be replaced.

Required Tools or Parts

For the lubrication procedure, a specific lubricant is required:

• Lubricant PF1 (50 gr/1.75 oz): Part Number 83 23 0 309 627

If mirror replacement is necessary, the exterior mirror assembly (Driver or Passenger side) part numbers will need to be obtained by referring to the Electronic Parts Catalog (ETK) or Aftersales Information Research (AIR) system, based on the vehicle's chassis number and specific equipment.
