Ive literally just been having the same issues as of late. FBO n55 f30 and can not pin point the issue. carbon cleaning injectors plugs ad coils all done within the last year but getting hard stutters (almost like a rocking chair) when quarter throttle at low speeds. pulled codes on BM3 reading 190302 tank ventilation 152d08 super knocking injection shutdown and 152508 cly 5 shutdown. i was running stage 2 91 octane and the problem was prominent. flashed back to stage 1 91 and reset adaptations before my 2 hour drive and car felt better with way less of that stutter but its still there

at 103k miles on it and as far as fueling i have a stage 2 LPFP but stock HPFP. maintenance is well kept on the car so im confused asf on what this is. talked to my tech (works for bmw met him when i worked there) and he said the only time hes seen it was when rod bearings were fucked. he told me to pull my oil filter and check between the cracks for any metal pieces and that will tell if the bearings are shot/spun
