My virtual dashboard goes to the sunset scene as usual when you switch the car off as normal. However, if not getting out straight away, it has always made a 'bleep' noise and gone black after a few minutes, presumably as a power saver. However, recently it's been doing that really quickly and not going black but going grey instead. I always assumed black meant it was completely off but the grey seems like the power is staying on.

Additionally, the hazard warning triangle seems to glow all the time - is this normal?

Thanks
