i recently purchased a used 2015 640i with only 3000 mileage. but 2 warnings keep pops up randomly. (drivetrain, and drive stabilisation. both with drive moderately notes).
another symptom is "rattle" electronic noises from under the engine hood. not sure what it is.
SA said the diagnostic report shows a bad valvetronic and speedcamshaft ?
im very frustrated and afraid that the DME is damaged since warranty is expired and i have to pay from my pocket.
did u manage to fix yours yet ? i also have the electronic rattle sound from under the engine hood. very frustrating.

I can't help you unless you post actual error codes, the letter/number value. I never had a reduced power issue and F series servomotors may be different.
