SIB 54 02 25: Convertible top service information
Convertible top service information on BMW G29 models (2021–2023); BMW explains the cause and the approved repair.
BMW service bulletin · NHTSA ID 11016441 · Mar 2025 · also written SI B54 02 25, B540225
What it covers
A service bulletin tells BMW technicians how to diagnose or fix a known issue. It is not a recall: a repair under a bulletin is normally paid by the owner unless the car is still under warranty or a warranty extension applies.
While driving on an uneven road, a “clicking”sound is heard from the front bow/cowl panelarea of the convertible top.
