My whole iDrive occasionally fails to boot. I've been taking close notes of when this happens and I thought it happened when it was raining. Then that got shot down when iDrive failed to boot on a sunny day. It now seems to be if I start it up, drive a mile or so, shut the engine off and restart it in between 3 and five minutes. What I do is then turn the engine off and wait twenty. Upon restart, iDrive comes on as normal.
What I see when iDrive hickups is the screen will go a light gray at first for about two seconds and then blank. It will then blink about every half minute and the LED on the SOS button will blink at the same time. I had the entire system replaced because it failed hard but now it's just intermittent and an annoyance.
