DB11 weird sound after parked from exterior.

I don’t quite know how to describe this or what it means but does anybody know what this is? Made this beeping noise 4/5 times after parking both yesterday and today.
Anybody have any ideas?

Exhaust valves operating/sticking?

Mine sometimes does the clicking thing but not the beep.

Wild guess - something to do with the door locking system?
