Hello I am new in this forum and i need some help about some sound on my Mazda, i have Mpv 2.0 EXCLUSIVE. The sound its come from the machine when I turn on the keys to start the car, and its not all the time, just maybe few times when I drive it. I go to mechanic but he dont know anything about that. I have some friends they say to me the forum Mazda from Slovenia are the best about all information. Thanks so much
