I have an 08 2.0HDI Exclusive,and have just had the same thing happen.I got two warning beeps,with no information about it on-screen,then the screen went blank for a few seconds,with radio off,and then it re-started and went back to normal. I recently had another incident which might or might not be related, in that I left the car ticking over and left for a few minutes. When I got back in, everything seemed to have returned to the default settings ie. seat memory,air con etc. That has only happened once, but I assume it is some sort of computer glitch.Love the car,by the way. :)
