I have 2006 M5, last week upon startup the center display did not come up. I also had the SOS with a line through it on the cluster display. I restarted the car with no luck in clearing the problem...car drove fine. The next day I started and the same issues except about 10 min later the display came on like I had just started the car. It recycled a few times..almost like a short. Anybody else have this issue? I have an appointment at Sun Motors in PA this week. More when I find out.
