So, I've been doing days of research on the forums and found multiple threads, however, most date back to 2019. Realizing it could be a plethora of things, any sort of solid answer? I read lifter tick, wastegate rattle, injectors, etc. it's not injectors, not convinced it could be the wastegate. I just changed the oil 3 days ago (5w30 BMW Twin Power), checked the catch can, oil filter and fished around inside the oil, no metal shavings, etc. just trying to be realist before I have someone tear into the motor. 2018 w/22k miles, BM3 stage 2, CH done, CBC done. No fault codes. I should note the car sits for a month or so at a time. Might just need to drive it more to keep some oil up top.
