Re: Dash Noise

My A6Q does something similar, but it's more subtle.  The
local Audi mechanic couldn't hear it, but most passengers
can after you mention it to them.  In my case the sound
is very sensitive to accelerator position (which I think means
vacuum), and secondarily speed (74 mph is the sweet spot,
but I've heard it at 49mph).  I've just about given up on it.
