Not quite sure what you are trying to say but, as said, you need the ignition on. To achieve that, you need to press the button without your foot on the brake. Even then, if you pull the dsg lever back, the engine will not start. Just to close the loop completely, the dsg lever will not move from park without the ignition on.
Is this a windup, or is it you who have been woundup? 😃
