I drove the car exceptionally hard one day and I threw the codes 152D08 and a 14401D (0 mechanical sympathy.) Stock 2019 M5 C with around 4500 miles at the time
I took the car in to get checked out, had the oil changed, dealer cleared the code and said maybe it was just bad gas.
I never really drove the car that hard again but... I ended up with an actual engine knock noise ~3000 miles later. Dealer replaced the full engine. Found bearing metal in the oil. Not sure if it was related but maybe be careful with this?
