This noise happens when im in accessory mode and while the engine is on. It affects my calls as the person im talking to can hear the noise on their end. Does anyone know where its coming from and how to fix? Tried unplugging the dcm fuse but no luck.

I think you posted about it before. Did you have the dealer check it out?
How long does it usually stay on? The sound itself really sounds like the EVAP pump. Maybe there is a leak or open spot on the gas tank? Gas cap all the way on? Go for like 3-4 clicks. Sometimes it could even be a faulty gas cap. Anywhere between the tank, fuel neck and gas cap. Happens when it's trying to pressurize or purge itself.
