You can unplug the ASD module.
The B&O will continue to play and everything else continues to operate normal.
Also no faults are logged (at least not on first look)
We had it unplugged in mine and everything was fine. I didn't have the the
time to connect it to the BMW system to do a complete fault scan.
Once it's out of hibernation (pending snow melting) I'll let you know
The other option is coding
All of the above applicable to those who actually can hear the ASD "induced" sound ....
