I drive a SL R230 at which the tank flap was no longer closed, unless I locked the vehicle with the key then the tank flap closed. During the drive, however, the flap stood up again. So I strolled around the flap a little until the central clearance suddenly gave up the mind. Now I also don’t come into the trunk with the emergency key, because the flap lock is defective. From the inside with the button, the trunk can be even I can’t open it. And I’m starting to run out of battery juice. I can’t do big rides because of the error message opening tailgate. Does anyone have an idea where to start?
