BMW E90 325i Exclusive (auto)

Afternoon guys,

I seem to have in-counted a problem, I was driving to church this morning and all of a Sunday excuse the pun, my wifes car a E90 325i exclusive 2007 model decided to flicker all the warning lights and then switch the radio off and stopped.

Then we decided to start up again after a couple of minutes and all was normal again, do you guys know what this could be?

Thanks
Khaya
