got intermittent sound twice in a week, music cuts, thought it was my usb stick and my music, nope, same with radio and spotify. Had to hard reset the system. Some members in other forums mention having to change the OSF Control Unit (part code 572035876G), others cite that is happens because of CarPlay or Android Auto.
As if the disappointment that for such a lovely car, such a poor audio system choice wasn't enough...
Anyone else experiencing this?

The OSF you mention is usually called the 5F controller. It's the "brains" of the infotainment system, a computer that lives behind the glove box.
Not seen anyone say it's causing HK problems, it has been known to be the cause of the various bongs and crashes on the Mk8 though.
It's an expensive part, £3500...unless there is a TSB for it they aren't going to even think about touching it. In fact the dealer isn't allowed to do any warranty work without the VW computer authorising them... No guess work or initiative allowed.
