Log the conditions before you spend. Swap the cheap/easy piece first on the 2023 BMW M340i and see if the fault moves. Don't erase codes until someone who can help has seen them.

I wouldn't throw parts yet. Two 2023 BMW M340is can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails.
