I just changed the spark plugs, coils, and CCV upper tubes, and coincidentally these errors started popping up right after.
I used NGK plugs from FCP Euro and Dinan coils. No misfires, so I am confident I did the install right. Used genuine BMW CCV tubes, installed them properly.
This really seems to be some kinda vacuum leak somewhere.
