What does "m sound" do?
Recently found the forums for unlocking the secret menu to control your exhaust valves. You can unlock it by using expert mode in BimmerCode.
Go to HU_MGU -> expert -> search "sound" -> aktivate the first 2 items "menu" and "configuration".
Now my question is what does "m sound" do? It pops up as the third item when searching sound.
