This is getting really annoying. About once or twice a week...for a month and a half now, right when I start my S up there's a very loud Crackling/Hissing sound. Always on a cold start, right when the engine is turning over(right as I press the Engine Start button), and it happens very randomly. My roommate is a mechanic, and every time he's available to stand next to my car during start up it never happens. The noise is definitely coming from the front of my S...Does anyone have any ideas as to what this may be? I'm completely stock...Also, the car seems to run perfectly fine afterwards...Thanks for any help/opinions.

If it's coming from the starter area - and it's sorta like grinding just after the engine fires...it's a normal complaint. with no fix, other than a new starter that I know of
