G21 dash keeps going blank

[Phil Cook]

Twice now my dash has gone blank. The central screen is fine as is the HUD.
If I turn off, lock and leave it’s ok upon return.
Has anybody has the same, and if, what was the fix?
Thanks

The demo I had did that. Saloon G20.
It gradually got worse , I had it a week.
I did read the codes and I’m sure it mentioned electrical fault. I also recall one of the systems (park assist for maybe) failed too.
I can’t help anymore , but because of how it depreciated and other failing systems get it to BMW ASAP.
The rental one I had , the electric windows failed until the day I returned it. I finally got them down and then they wouldn’t go back up
