For anyone "in the know"
... on my new '17 GTI Sport (US model, 400 miles on the clock, thanks) the car settings have Normal, Sport, and Custom for Driving Mode selections; and in Custom there is Normal and Sport for the Engine Sound item. This is AFICS the Soundaktor control that is provided (w/o using VAG-COM of course).
Question is, does anyone know what the sound levels are in Normal and Sport ... I'm guessing Sport is 100% volume but in Normal mode it's nowhere near that. There's a clear difference.
In Normal mode I don't find irritating and there's no rattles and such that I can hear, cabin sound volume putting around and motoring gently down the highway seems fine, with a bit of extra noise when accelerating more-than-gently (which must be a combination of actual engine/exhaust and Soundaktor).
I'm curious whether going to the effort of getting the volume dropped to nil in Normal mode would be a tangible difference, or just splitting hairs.
