The invention relates to a method of operating a fuel gas tank system (1), comprising at least one fuel gas tank (2) for storing fuel gas at high pressure and a valve assembly (3) inserted into the fuel gas tank (2) for removing fuel gas from the fuel gas tank (2), wherein a shut-off valve (4) which is integrated downstream of a flow restrictor valve (5) in a removal path (6) of the valve assembly (3) in the direction of removal, which opens into a gas line (7), is actuated and opened to remove fuel gas. According to the present invention, before the shut-off valve (4) is actuated, a check is conducted in a step (a) to determine whether activation of the flow restrictor valve (5) is to be expected and, if the flow restrictor valve (5) is expected to be activated, the shut-off valve (4) is actuated several times in succession at certain time intervals in a step (b). The invention furthermore relates to a control device for carrying out steps of the method.
