2023-2024 BMW 5 Series / i5 Exterior Mirror Squeaking TSB

Owners of 2023-2024 BMW 5 Series and i5 models may notice a distinct squeaking sound coming from the exterior mirror assembly when it folds in or out. This issue is addressed by BMW Technical Service Bulletin SIB 51 02 24, which provides a specific repair procedure to eliminate the noise. This bulletin helps technicians diagnose and resolve the BMW i5 exterior mirror squeak and similar noises in other affected models.

Symptoms

The primary symptom described in SIB 51 02 24 is "A squeaking sound is heard when folding either of the exterior mirrors assemblies in or out." This noise typically occurs during the automatic or manual folding operation of the side mirrors. If you hear this BMW i5 exterior mirror squeak, your vehicle may be affected.

Cause

BMW has identified the cause of the squeaking sound as "unfavorable tolerance positions within the exterior mirror assembly." These slight variations can lead to friction and noise as the mirror components move during folding.

Repair Procedure Summary

To resolve the BMW i5 exterior mirror squeak, technicians should follow a specific procedure outlined in SIB 51 02 24:

1. Verify the Issue: Confirm that the customer's vehicle exhibits the squeaking sound during mirror folding.
2. Initial Cleaning and Lubrication: Manually fold the exterior mirror assembly inwards. Clean the sliding surface of the mirror assembly and apply PF1 lubricant. Then, fold the mirror outwards, clean the sliding surface again, and apply PF1 lubricant.
3. Re-evaluation: After cleaning and lubricating, recheck if the squeaking sound persists.
4. Replacement (If Necessary): If the noise is still present after lubrication, the affected exterior mirror assembly should be replaced.

This correction aims to clean and lubricate the sliding surfaces, thereby resolving the friction causing the noise.

Required Tools or Parts

For this repair, the following parts may be required:

• Lubricant PF1 (50 gr/1.75 oz): Part Number 83 23 0 309 627. This lubricant is essential for addressing the unfavorable tolerance positions.
