BMW 750i fuel tank cover cannot be closed on BMW 750i

Some BMW 750i owners report experiencing difficulties with closing the fuel tank cover, which may be attributed to several potential issues. These include a malfunctioning fuel filler door cap buffer ejector that may need to be checked or replaced. Additionally, problems with the locking system can hinder the closure of the fuel tank cover, necessitating an inspection to ensure the mechanism is functioning properly. In some instances, owners find that manually releasing the cover by pulling the green cord under the hood resolves the issue. Proper engagement of the fuel filler cap is also crucial, as it must be pressed down firmly until it locks. Furthermore, a clean and well-lubricated mechanism is essential for smooth operation, while excessive grease should be avoided. A faulty tank vent valve can also lead to erratic idling and affect the fuel tank cover's functionality. Lastly, inspecting components like the part joining the filler neck to the fuel tank is important to ensure there are no obstructions. Addressing these concerns is vital for resolving issues with the fuel tank cover on the BMW 750i.
