E60 545i electrical gremlins
 

Hello gang, new poster but have been reading a lot on this board.
My 2004 545i has a problem,
when I start it up in the morning and start to drive it the speedo, idrive screen go out for a few seconds, and the come on again, hut when that happens all hell brakes loose, the dash lights up like a christmas tree, it does this quite a few times, I drive it like this for 5 minutes, then stop and turn the engine off and on and then everything is back to normal.
it has had some current draw issues which I havent been able to find where attached a video....
