i get this clicking or popping sound when i'm just sitting in the car w/the engine on...this sound also happens after i shut my car off and after about 3-5 minutes...this pop noise happens. sounds like it's coming from the brakes or something. does anyone know anything about this?

 

see the post below you. Same problem. It's your car cooling down. Don't worry it's normal.
