Has anyone ever heard a high pitched electronic squealing noise that seems to come from somewhere under the Supercharger, when the engine is off ? It squeals really quietly for about 5 seconds and then after 2 minutes it does it again. I can hear the noise when my car is in my garage and nothing is on. It almost sounds like pressure being released over and over again, but real low. Any info on what this might be would be greatly appreciated, because if I take it to the dealer it probably wont do it. Thanks in advance, this is driving me crazy!
