Hi 4.6is Ryder
My X5 did the same some months ago.
Got in the car, started up and the screen started to flash then open up
then close then open up again, it went on for about 3 minutes until I turned off
the engine.
I went and rang a local dealer who said he thought it just got its "Knickers in a twist"
I went back out started the car and everything was fine, it hasn't done it since!

X5 Gremlins!!!
