I am having a strange problem with my 2000 S80 T6. While driving I am experiencing a hissing noise coming from under the dash/foot well on the driver's side. At first I thought that is was a speaker picking up road noise but then I realized that no it was not a speaker, it was coming from under the dash. The strange thing is that if I even barely tap the brake pedal when I hear the hissing it stops. When I release the pedal it sometimes comes back right away, sometimes not. In addition to that I also get a high pitch whine that acts the same way as the hissing, but it is tied into the gas pedal. Both of these noises occur about 60% of the time everytime that I drive. Does anyone have any idea what is going on?
Thank you in advance,
-J.P.
