Note: Perform at your own risk.
If you are able to raise the rear end and remove both rear wheels, this will make the process much easier. If not, we will continue on!
Located in the Fender Liner, there are "4" T25 torx screws each side. Take them out and pull the felt liner back so you can access 4 more T25 torx that hold the bumper to the body. If you decided to take the wheel off, you may want to just go ahead and remove the full liner.
T25 Torx screw in the liner.
If removing the full liner, these plastic nuts are 10mm.
Liner Removed to reveal the remaining "4" T25 torx screws. One going up from the bumper corner into the rear quarter. One at the bottom, retaining the bumper to the visible plastic bracket. The remaining "2" can be found parallel, in between the other two.
Now that all fender liner screws are removed, you will need to remove "2" more screws centered under the rear of the Macan, holding the black plastic section of the bumper to the bottom of the vehicle.
Once all these are removed, the hard part is over.
Moving to the trunk, open the rear hatch.
Locate the Black plastic covers on the inner side of the taillight.
Using a panel pry tool, pop the inner most portion of the cover towards you, and then pop it off the side of the taillight itself.
At this point, if you are removing the taillights, you can remove the "2" T30 torx screws holding the taillight to the body. Otherwise, remove the black T25 screw going down into the bumper, that was covered before. Perform on both Drivers and Passengers side.
Next remove the lift gate bump stop from the bumper completely. Repeat on both sides.
Next tape off the bottom of the taillight and rear quarter panel to ensure when removing bumper that it does not scratch the paint. With the areas taped, start at the corner and gently pull the bottom of the bumper out and up as you pull the top corner out and away from the vehicle. There are tabs that the bumper is slipped over and the bumper with pop off them. Do the same under the taillight.

Repeat to opposite side.
With both corners released as well as under the taillight, pull the center section of the bumper off a few inches as there is a single connector on the passengers side that will need to be unplugged. With the harness unplugged, the bumper is now free of the vehicle and can be set aside.
At this point, the bumper removal is complete and you can follow the guide in reverse to re-install. Otherwise we can continue with the taillight removal.
With the "2" T30 torx removed earlier....
We will move to the interior of the trunk and on the sides, you will find access panels. Pull these panels as they just pop off. You will find on the drivers side 2 modules, first a Bose module screwed to a bracket. Remove "4" nuts from the bracket and pull it out and away.
This will now reveal the second module behind. Remove the "3" nuts from the inner quarter and pull it aside.
Behind the second module, you'll find a T30 torx screw that holds the back side of the taillight in the housing. Back the screw out and pull the screw from the housing as it has a clip sleeve that it sits in before the threads make contact.
With the screws all removed, you can now slide the taillight out of the housing and plastic lower bracket.
Note Below, the hole in the back of the taillight bucket, this is the third screw location.
At this point, you can disconnect the taillight wire from the back of the taillight itself. The harness can be unplugged from inside the rear quarter however the plug end is too large to fit out the hole.
At this point you have removed the Bumper cover and taillights!
To re-install please follow directions in reverse order.
Hope this helps someone!
