Fiesta st mk7 Bleeping sound on engine start up

[Tony_moto_87]

Hey everyone

I'm a new owner of a mk7 Ford fiesta st and have started getting a bleeping sound occasionally on start up when the car has been left for a while... no idea why

Doesn't happen all the time.
No warning lights at all and car drives perfect.

Thanks for you input and help.
Cheers

Mk7 = 2017?

Is this the a-famed 'ding, ding, ding' that periodically occurs, (even when you're not around I discovered)?

For the US vehicles, this seems to be related to the BCM security system. I suspect it looses confidence about the state of all entry points and so periodically signals a 'ding, ding, ding'. Lots of banter about this on the forum. The solution is to cycle all six entry points... hood, hatch, and all four doors. Provided their respective switches work, the BCM is then satisfied that it knows the state of them all. Someone implied that it monitors the state of the moonroof and side windows but I'm not sure whether that's the case.
