Normally, you need a scan-tool to put the headlight leveling electronics into an adjustment ("basic settings") mode, before you adjust the mechanical adjustment aiming screw on the back of the headlight housing. In my experience, if you are making minor adjustments of the screw (less than 3 turns), there is no need to use a scan tool.
The headlight adjustment screws for a PDLS+ LED headlight (2019 Macan) are shown below. The small plastic "anti-tamper" plug (outer screw) must first be pried out with a very small flat-head screwdriver, to access the allen-key socket. I recall that turning the screw counterclockwise raises the headlight beam. The inner screw, without the anti-tamper plug is the Left-Right beam aiming adjustment. Using a sharpie marker, put a small dot on the white adjustment screw, so you can see how far you have adjusted it. I typically will turn the screw 1 rotation CCW, and then see if I am satisfied with the aim height of the low beam.

I recently had the right headlamp replaced under warranty and the dealer released the car without proper alignment. Is this something that I can adjust with the above steps or would it require adjustment that would damage or throw the PDLS+ system out of spec? That's about a 20 ft. distance.
A scan tool was mentioned in the post above. Is there something other than the full PIWIS 3 that can be used for this adjustment mode? I am happy to use this as an opportunity to invest in a good scan tool that's reasonable (<$1,000).
Try it...first put a small dot on the screw, with a sharpie, so that you can return the screw to its original position.
I asked at the dealership and they tell me this is standard for a German car to have the drivers side lower for oncoming drivers and the passenger side higher to illuminate signs, but I've never experienced such a prominent dip.
I used the dot method this morning and adjusted the left/right but i haven't been able to get rid of this V on the drivers side.
