I have a retrofitted B7 S4 MFSW installed and this has happened several times but not for very long and not for very long.
As I was trying to skip to the next track on the Phatbox the wheel buttons stopped working. I even tried the volume up or down and it didn't work either.
The lasted for about 15 minutes and then I received a phone call over the OEM BT and when the call ended the wheel functions where working correctly from there after.
I am bringing it up because I just saw this post on Audiworld about the same thing.
