Humming/Acoustic Whine
Hey folks,
I've noticed my car makes a consistent humming sound when I approach highway speeds. It is most noticeable if you stay in comfort and starts at around 80km/h. You can really notice it if you get up to 80-100 and then do zero to moderate acceleration. Wondering if anyone has experienced anything similar? I thought it might be from bent wheels or a wheel bearing going. I brought it to the dealer as I have the extended warranty and they are already fixing an AC issue but they have not been much help. They acknowledge the noise, but say it is from 4 "Choppy" tires, that are not BMW "star" rated and from the M performance exhaust as well. I'm pretty annoyed by the tire comment as they were put on brand new by the BMW dealer (different then this one - out of area) and I had an alignment done a couple weeks after brining the car home. Has anyone experienced choppy tire wear before and know what caused it? Could the sounds be the exhaust drone I know some people dislike between 2K to 3K RPM? Appreciate any suggestions. |

I disabled ASD with Bimmercode as a test and the whining sound in comfort mode was very decreased. I'd say the sound you're hearing is the exhaust and amplified by ASD.
I ended up turning back on ASD since the cabin was way too quiet with the windows rolled up. |

Edit: For ASD volume you can tweak the Power Class setting in expert mode. https://f30.bimmerpost.com/forums/sh....php?t=1319639 For engine tone the setting is in the Engine setting in expert mode. Last edited by eff32fl; 08-13-2022 at 03:36 PM.. |

It should be instant but someone in the thread I posted above said their change didn't take effect until the second time they drove for some reason.
