Yes search function is your friend. With that being said the DME cover is the black plastic lid in the engine bay upper left corner. Remove the torx and the relay is there its the pink" salmon"colored one.

Then you have a leak some where in your system, try and put it on a lift and trace the leak

You may have air in the system. but you could try just cycle the gears a few times although you wiil need to hook it up to a machine to get it bled properly

Are you able to cycle the gears? R-N-1-2 without starting can you hear the pump working if you can?

There is some noise when starting the first time but I'm not sure if it belongs to SMG Pump or Patrol Pump. yes I remember I tried to cycle N-1-2 there were fine
