Mercedes-Benz ML350 difficulty filling gas tank past half full due to auto shutoff at pump on Mercedes-Benz ML350

Some Mercedes-Benz ML350 owners report experiencing difficulties when filling the gas tank past half full, as the automatic shutoff at the pump may repeatedly activate, making the process slow and inefficient. This issue can stem from the venturi effect utilized in the vehicle's fuel system, potentially indicating a problem with the high-pressure pump. Additionally, some owners have noted that the fuel fills up quickly only to stop suddenly, leading to spillage and further complications during refueling. To address these challenges, it may be beneficial to check components such as the charcoal canister valve filter, which could be contributing to the issue. It is also recommended to have the fuel control module and instrument cluster components inspected to identify the root cause and ensure the fuel delivery system is functioning properly.
