Rapid ticking noise underneath P4

[Stokes]

I went to setup my P4, updated the firmware without any issues. The P4 is sitting on my desk powered up with the lights blinking and I hear a very rapid low pitch ticking noise coming from below, where the bottom sensors are.
When the battery is pulled out and powered on I do not hear the noise, so it doesn't seem to be from the battery.

Is this common or do I have a possible issue?
Has anyone else heard this noise?


Thanks

Mine does this too. I'm pretty sure it's the VPS.

Ok that doesn't really help.

It's the VPS. It's sonar. Like on a fishfinder. A pulse is sent down until it bounces back to the sensor. Measuring the distance. It's normal and all of them do it.
