I bought a new S P100D about a month ago, recently I have noticed excessive whine between 30 and 40 mph. When I initially picked the car up I was thrilled at the lack of whine compared to our S 85D. Now I am noticing excessive whine noise between 30 and 40 mph. Anyone else having excessive whine? (Note: I have never used Ludicrous plus mode, nor have I done any standing start acceleration tests with it, yet.)
