constant whine
Ok so I have an 2011 no NA, premium sound, and I have the dreaded constant whine, whether car is running or not, radio on or off. Radio volume has no effect. It only goes away once the car powers it's down. I suspect an amp issue since, I know the amp is on when the car is on.
I have heard there was a software fix. Comments...? Also as a side note, why does the AMP have to be powered on when the car is on? Why can't it power up with the radio? Does anyone have any info suggestions or magic spells to cast this daemon out?

Your post makes it sound like this happens all the time
I have never read about this as an issue Can you post some links to other threads about it so we can read up on it? Seems like something I should get familiar with. |

Is the sound coming from behind the passenger seat? Could be Hpfp in that case. From the engine bay? Look at the turbos. But really, you can't diagnose a sound on the interwebs.
