Again, the valves were set to completely open.
I decided to code ASD off via bimmercode. I was a little confused as to if it worked or not, because all the interior drone disappeared, but I still heard the burbles when sound control button was on. When the button was off, the burbles went away again. All while the exhaust valves were fully open through the vsc2 controller.
I finally had my husband drive the car, so I could hear if it was an actual difference with the exhaust sound burbles or if ASD was truly not deactivated through bimmercode. Indeed the burbles were real, not fake sound being pumped in.
I guess I'm just confused as to how complex this "sound control" button thing is. Because if my ASD is coded off, and the valves are forced open, what is the variable giving it authentic burbles with the sound control button on (green light) vs off.
Just food for thought ��

ASD on = Fake pumped in noises
Sound control button = Turns off some of the ASD but also turns off actual burbles in the factory tune and changes exhaust valve control settings to close the valves unless you are at a very high load/throttle position.
