Neither the 2018 or 2019 codes work for the SAND color. I have 3 shops working on it. The PPC numbers do not work in their systems and so the only code that is meaningful to them is the "RAL Number" and you'll notice its missing for SAND.
I used an app on my phone to capture this NTC Color (97.8% match) for my 2022 Red Roxor. You'll see the 5 kdifferent paint codes for different mixing systems. Hope it helps.
