Hi all -
Just thought I would share how I successfully updated my US/North America Model 3 (2018 AWD) to charge from European CCS2 chargers (exception: does not work on V3 superchargers due to error cp_a139 and cp_a066).
First: I purchased the CCS2 to TPC (Tesla proprietary connector - now known as NACS) from EVSEadapters. I have used EVSEadapters in the past and have been happy with the quality of products. Unfortunately, it seems they may have *slightly* misrepresented this adapter. The website claims the adapter will work out of the box to enable US teslas to charge on European CCS2 chargers. The truth is you will need to modify the adapter or modify your car first.

Option 1: retrofit your model 3 (or model Y) to have a European charge port ECU. This will disable the use of TPC/NACS superchargers but will work out of box with the adapter.
Option 2 (what I did): modify the adapter and place a 160 ohm resistor between PP-PE contacts. Assuming you have CCS adapter support enabled this will allow you to charge at all CCS2 stations except for V3 superchargers while maintaining compatibility with TPC/NACS superchargers for when you return to the US.
To do this, I used a hacksaw to cut open the adapter. It has 5 screws but they have had the heads removed to prevent tampering. Once open, solder a 160 ohm resistor between PP-PE contacts. Then reassemble adapter. For my first test, I held the adapter together with zip ties. I am now gluing everything back together and will add a few screws.
I am here in Europe for a year or two and even without the ability to use v3 superchargers this setup should be more than sufficient for making long trips throughout Europe (3rd party CCS2 chargers are nearly everywhere).
Next projects:
-EU modem replacement
-DAB radio replacement
