I took it right back to service so my advisor could run a scan on it while the screen was no signal. This time they were able to produce the fault code that called out a faulty CIC control unit, and a second page said something about the head unit but not sure if it was to replace or reprogram after CIC replacement. No call today from service so I'm sure they had to order the part. I'm pretty sure the replacement of this and/or the CIC head unit is the correct fix. I will post back hopefully in a couple of days. The key is to drive it right to the dealer so they can pull the codes while the no signal is displayed.

Well, I've had the CIC replaced - didn't make any difference. BMW Tech support told me that the SW reprogramme fixes this issue in "99%" of cases (which is interesting considering I've been told in the past that they haven't seen this problem before - which in itself seems to fly in the face of reports on the internet).
So, current plan is to change the HU, which is on order from Germany. Last few times the problem has occurred, I've taken it straight to the dealer so they can see/diagnose the problem themselves (it didn't help).
Hoping to get the car back in a couple of weeks, so will keep all updated on here.
