Question for those of you with a B7 (mine is an RS4 with RNS-E). Regardless of how long my car has been off, I can hear faint white noise coming from the speakers. The sound is similar to what you might hear from relatively quiet HEPA filter.
I realize that the audio system on this car can be powered on for a period of time after keys have been removed from the ignition. Curiously enough, I can leave my car off for 24 hours and still turn the radio on/off (with no keys). Also, I can't get a remote on/off to work from the wiring on the amp in the trunk.
So, is my car possessed or is it just me? Does anyone else's car produce white noise whenever off?
