All I can tell you with my Macan 4S is that at the 50% setting it was charging at 5.3 kW, and at the 100% setting it was charging at 9.6 kW. I was kind of bummed that it can't charge at 11 kW like my Rivian using my Rivian wall charger (even though the manual says that it can charge at that...
If you push and hold the 🔌 button for 2 seconds, it will switch from 50% to 100%. It comes set at the factory at 50% for whatever reason. Took me several hours of scratching my head and searching in the manual until I finally found it.
I use Dr. Beasley's Fine Leather Cleaning/Protection Kit (comes with all of the applicators and accessories). You can find it on Amazon, and it works great on the Macan EV. I use the Vegan Leather Kit on my Rivian. Really good products, and the odor is pleasant.
I had this problem too. The solve was to set the boot lid open height at the mid way point, and then open and close it a few times (it should only open up to that midway point). Then, I could push the boot lid up higher, set it and it would close. See if that helps.
