2004 BMW 525i please help wih this driver side noise

Hard to understand a noise problem online. Is there a chance it is coming from the passenger front tire? Breaks often times have little metal feelers that start to squeel when brake pads are getting thin. Does it increase or decrease with pushing on brakes. Turn off air and radio to better hear.

Thank you SO much. But I checked the brakes. They are good and there is no noise with braking. I hear it more when I drive the car in the free way and I go on the bumps. It seems like something is loose. Wither the door, or airconditioning. I thought maybe its from radio. But I turned it off and still hear that. Please help!

You may have to listen to the noice a few more times to better understand it. The good news is that it is not coming from the engine, brakes, shocks, or any other component that could effect the driving 9or so we think at this time) You need to look for patterns. Turn the ac off (and I hope by ac you mean heater bc it is COLD) is the sound there when it is off. Is the sound more like wind, metal hitting metal, or metal scratching metal. What do you think the chaances are that there is something loose in the door, like one of the metal wires used by the handles. Does the door function properly? Roll down window and see if things change. You may need to donate a few dollars to get a pro's help
