2024 BMW 5 Series Fuel Tank Evaporative Leak SIB 16 02 25

BMW has released Service Information Bulletin SIB 16 02 25 to address a potential manufacturing defect in the fuel tank of certain 2024 BMW 5 Series (G60) vehicles. This issue, identified as a BMW 530i evaporative leak, can lead to noticeable symptoms for vehicle owners.

This service action is crucial for maintaining vehicle safety and environmental compliance, as evaporative leaks can release fuel vapors into the atmosphere and potentially pose a fire risk, though not explicitly stated as such in the bulletin.

Symptoms

Owners of affected 2024 BMW 5 Series vehicles may experience one or both of the following symptoms:

Diagnosis / Trigger Conditions

The root cause of the BMW 530i evaporative leak is an improperly plastic-welded assembly cover on the left side of the fuel tank. This manufacturing defect allows fuel vapors to escape, leading to the symptoms described. Technicians will confirm the issue by checking for an open service campaign status in BMW's systems.
