You can only hear it if I lower the window and no music playing because it's not super loud but it's noticeable. It's not the burbles by the way. It's like a psssss, psssss noise after accelerating as it downshifts.
Sorry if I sound like an idiot but that's as best as I can describe it.

Wait is this a manual or auto?

It's an automatic and to update you guys. I called the bmw dealer and explained the situation and I was told it was normal, they said it's the pressure release valve ? They said I'm good. Idk but that noise is kind of annoying. I'll try to get some sound clips when I get a day off.
