2018 M550i whistle 55-60 mph

bummedic · 02-09-2021, 02:07 PM

Anyone get a noticeable whistle between 55-60 mph that sounds like it's coming from the driver's side? I haven't had or driven the car for very long (new to me CPO with ~30K when I bought it and I've put on about 2.5K miles... mostly long commutes, no launches, and occasional spirited sport mode driving) and can't say that I can really tell or notice the so-called turbo-whine or spooling, and I'm wondering if that's what I'm hearing. It doesn't seem to do it for the first while as the car is warming up, but then I notice it consistently. It's most noticeable when I pull my foot from the accelerator and let the vehicle coast down into that range. It's louder at the top end then eventually disappears as the speed continues to drop. I'm going to try and listen more for it, as I'm usually listening to something while driving. Just curious if anyone else has noticed anything. Oh yeah, 2018 MY, and doesn't seem to matter whether in comfort/adaptive/sport/sport+.

It does sound as though it has a spooling up/down character to it, but not sure why I'd hear it so distinctly in this speed range.

You may want to have a look at the alternator or water pump. Just as precaution, since it’s relatively recent transaction.

To answer question... no whine coming from mine or whistle at any speed. Thus suggestion above.
