2021-2022 BMW X-Series/3-Series Lower Air Flap ELW

BMW has issued Service Information Bulletin (SIB) 01 03 25, announcing an extended limited warranty (ELW) for the Radiator Grille's Lower Active Air Flap Assembly. This warranty extension applies to certain 2021-2022 BMW X5, X6, X7, and 3-Series vehicles, covering defects in materials and/or workmanship for 15 years or 150,000 miles from the vehicle's original in-service date.

This bulletin, SIB 01 03 25, supersedes a previous bulletin, SI B01 03 25, dated April 2025 (note: the original document contains a typo for the superseded bulletin date, but this is the reference provided). The extension aims to address potential operational issues with the lower active air flap assembly that may occur over time.
