Dumb question, but is it possible that the fuel (98 RON, but it has 20% alcohol...) ita the one causing this?

The P0420 code is disabled in the ROM file I sent you. So if you are still getting it, it's likely you didn't load the file correctly
P0420 should have nothing to do with fuel formations or exhaust leaks.
