For a wk or so my Check Engine have been on. Prior to the light coming on the auto top came on twice. I had to pull over and press the close button eventhough the top was closed very wierd. I am hearing a grinning noise when I pull off and when I go over speed bumps the car is now makes a annoring sound in the front. I'll be taking it to a Volvo specialist but what would this noise indicate?
