Weird beeping sound from dash ford fiesta mk6

[GeorgeF21]

I drive a 2008 Ford Fiesta Zetec mk6. It has no parking sensors and I keep hearing a beeping sound from the dash, same one that plays when the door is opened or petrol goes below 50 miles. Engine oil level is fine, there are no messages or warning lights popping up, and I just generally have no clue what it may be.

If you are able to mute audible warnings, it might eliminate the possibility of  intermittent sporadic alarms triggering the beep ?
