I have G21 (Sept 2020) and has been fine for 9 months then I keep getting an error when selecting reverse saying my sensors are dirty and are being turned off.
However, the car is spotless and I have cleaned the car, especially the sensors many times.
The problem seems intermittent, I parked yesterday when this message came up. When I went to drive away there was no problem or when I parked again but when I cam to leave I got the error.
This has been happening every day for the last few weeks.
I wonder if one of the sensors is failing intermittently.
See the attached photo of my screen showing all sensors but doesn't show which is faulty?
Has anyone else experienced this?
I think it needs booking in before the warranty runs out.

Mist be a faulty connection on one of the sensors. Best to make an appointment at your local BMW dealer.

I took it to my dealer and they confirmed a faulty front right centre sensor.
New one ordered which will need painting and installed in 2 weeks time on Warranty.
