That’s is not cam phaser rattle. Phaser rattle is a very distinct clatter that lasts only 2-5 seconds and then immediately goes away. What you’re most likely hearing is the high pressure fuel pump and wastegate rattle, which are normal and most audible on a cold start.
Started it again this morning and no noise. Keeping my fingers crossed but will see how it is every morning this week and report back.
Whatever it was, I'm not quick to believe it's the DI fuel pump, wastegates or injectors. I've had turbo DI cars for over 10 years now, I'm well acquainted with all those noises.
