Ok so i have a 325is and after i changed the alternator the car has been making the weirdest noise like some kind of "whistling." This sound becomes alot louder when i turn on my lights and when the micro motor is used in the windows and when i roll my windows all the way up and down.. THis noise is becoming very annoying and when i applied some belt spray the noise mellowed out but came back to haunt me a few minutes later
