I have had a similar sound since I bought mine second hand late 2010 model. .Dealer spent hours with 6 electronic ears all over the vehicle ,no real conclusion on what it is.Noise is there in all gears plus neutral standing still, from around 75-100kph or at certain revs relating to those speeds then disappears ,its a wrr wrr whistle /whine. Bloody annoying. Ran motor without serp belt, checked everything. However mine also has a big bore exhaust and muffler.!!
I can only conclude its a motor resonance noise, maybe associated with the non std exhaust system. There have been a couple of others over the last few years with the same problem.
