I'm with you 100% on this one Kramer. I've narrowed down the noise to just about your referenced area too. It's particularly loud around 50 to 55mph if I'm light on the gas and then lightly add pressure to the gas pedal.
I took the service manager for a ride yesterday to illustrate the problem. To my surprise he acknowledge the problem too. He told me that he would first check the wheels and tires. If that fails (which we both know it will) he will then call Porsche for help.
I have an open appointment sometime next week to resolve other issues but since we're waiting on parts that may be pushed back. Let me know how things go with you.
BTW, my auto is one-week-old w/ 700 miles and the "Service due in 3000 miles" warning came on this morning. Go figure.
I've owned a lot of cars/trucks in my time (20 +/-) and I'm so disappointed with this vehicle that this will probably be my last Porsche.
