What's this sound like? '04 325i.

No OBD2 codes, no CEL, no difference in performance as far as I can tell. Perhaps secondary air pump? Doesn't get any louder under acceleration so I can only really hear it when it's idle.



The camera makes it sound louder than it is, but I'm glad that's the case for the video.



And don't hate me for my "black" style 45s. I have a set of style 72's getting powdercoated as we speak :)



edit: water pump is new as of 5K ago
