I have a whine as well most audible between 2.5k and 3k rpm. I've replaced the tensioner and the alternator and belts. I also replaced the oil pump for fun. I briefly ran the car without the main belt to rule out power steering. It has been doing it for at least 5k miles. Seems to be getting a bit louder but I could just be getting more paranoid over time. I finally took it to the dealer and they said they had no idea. They said “it might be normal”. I think it is annoying and drowns out the good noises.

Not sure how to upload a video but if you are on the m5 Facebook group: https://m.facebook.com/groups/849512...ibextid=v7YzmG
