Drove about 300 miles this weekend, and tried to pay attention to any strange noises at lower speeds.  Interestingly I do hear a faint whine at very low speeds (<50kph).  It's a noise I'd characterize as gear noise though so not certain it's the same thing.

It was very, very faint as I had to have the window down and basically be coasting to hear it.  Not sure if when I accelerated the noise of the exhaust masked the noise or loading the gear train eliminated it.  Definitely interested in hearing what Porsche says. 

Off topic, went by my dealership and saw their new GT3, wow...
