When running the climate control, there is a whistle like sound somewhere on the passenger side. Anyone else experience this and have a fix?

I experience this on the driver's side. This happens randomly. It isn't consistent and can't be heard with the radio/music on, but is quite loud sometimes. I haven't had it fixed because the dealer can't replicate it.

There is a TSB on this. In fact, there is two TSBs on this. One addressing the concern on the B Pillar vents causing a whistle (that can sound like it’s coming from the front area window vents, passenger or driver) as well as a TSB addressing wind noise/whistling due to exterior trim pieces. I’d have the dealer check for both - they did mine and it’s gone. Funnily enough all my BMW vehicles did this, X5, M4 et cetera. Right now I have a brand new 2024 X5 loaner that also does this!

Attaching potentially related TSBs.

I'll verify if the position of the vent affects the sound. If so, I think you nailed it. Thank you!
