I am not sure if there is a problem with it and I live a long way from a dealer.
Distance should not be an issue re diagnostics. Simply FaceTime or Skype with your dealer to show them the issue, or worst case, call them. Anyway, that's what we do when a client has issues who isn't located close to NYC or LA; the USA is quite large and we have clients thousands of kilometers away, plus clients who are traveling to the other side of the world.
I suggest this, rather than email or web, primarily because of the auditory and timing nature of the issue. It reminds me a bit of Click and Clack the Tappet Brothers from Car Talk; reading a transcript of their show would be far less illuminating than hearing it as so many car issues are auditory in nature. If your dealer hears the issue they may quickly identify it as the cause of X, Y, or Z and quickly tell you that it either needs to be sent in or that some menu option you have selected is not compatible, or this is what happens when you have mismatched firmware etc etc.
Anyway, a vote for contacting your dealer; it's literally their job to help and to make this as painless and brief an annoyance to your experience as possible.
