Side assist warning

[parsman]

Hi everyone
I'm getting an intermittent alarm warning indicating that Side Assistand rear view is not functioning on my 21 plate Formentor VZ2 310.
This is more of a nuisance alarm and does not effect driving the car.
Has anyone had this problem before and is there a quick fix. I assume the overtaking side assist is driven from a sensor on the wing mirror.
Look forward to any help
Regards,
Parsman

Side assist is radars behind the rear bumper. Impossible to know what the issue is without doing a diagnostic scan
