Mine has returned after a long absence.  Occurs when accelerating around 2500 - 3000 revs, going up hills.

 

Not as bad as it once was, but annoying nonetheless.  As before, a 10 second blast of the fan through the middle dashboard vents takes it away so it must be something to do with the fan unit in behind the dash.  

 

Anyone else still get this?

I have a little buzz from somewhere. If I push on the trim where it has the Sportline badge it disappears for a bit.
