2024 BMW Tailgate Creaking/Groaning Sound TSB

BMW has issued Service Information Bulletin SIB 51 46 16 (Revision 04) to address a common issue where owners may hear a creaking or groaning sound when operating their vehicle's tailgate. This bulletin, which replaces the earlier SI B51 46 16 dated May 2023, outlines a straightforward repair procedure to eliminate this noise.

The issue affects a wide range of BMW models, including various F- and G-chassis vehicles. For instance, if you own a 2024 BMW X5 and notice a persistent noise from the tailgate, this bulletin provides the necessary steps for diagnosis and repair.

Symptoms

Owners primarily report a distinct "creaking/groaning sound from tailgate actuator" when the tailgate is opened or closed. This noise can be quite noticeable and may indicate an underlying friction issue within the tailgate mechanism. Technicians are instructed to verify a "popping sound from the tailgate" as part of the diagnostic process to confirm the presence of the issue.

Cause

The root cause of the 2024 BMW X5 tailgate creaking and similar noises across affected models is identified as excess friction. This friction occurs within the tailgate actuator and/or striker, typically due to the entry of dirt and dust into these components. Over time, this accumulation can impede the smooth operation of the tailgate, leading to the audible creaking or groaning.

Repair Procedure Summary

The repair outlined in BMW Service Information Bulletin SIB 51 46 16 is a simple, mobile-friendly process focused on cleaning and lubricating the affected parts. First, a technician will confirm the presence of the popping sound from the tailgate. Next, the tailgate actuator and striker are thoroughly cleaned using a dry cloth; compressed air may also be used to dislodge stubborn dirt or dust. Following the cleaning, a small brush is used to apply a special lubricant, "Special Grease RHF 1", to both the tailgate actuator and striker. Finally, the tailgate is opened and closed multiple times to ensure the grease is evenly distributed, allowing for smooth, quiet operation.
