Here's a strange one, start car and the radio works for a few seconds then silence screen shows the channel and the txt of the song playing, no Bluetooth , no usb stick, no phone, can't turn the screen off and it won't take a master reset. 
Booked into dealers but can't get it looked at till 4th Aug.

Started the car this morning and everything back to normal, very strange.

If you do a search on google for VW blank screen (or similar) loads of threads come up.  Softwarey type issues have been fairly common over the years.....
