High pitch whine while sitting parked in the garage

[A-Wimoweh]

So lately I have been noticing a high pitch whine coming from my car while its parked in the garage. Its faint, hard to localize, and it sounds like something is spinning very fast. I think it is coming from underneath the front of the car somewhere. Plugging in the car does not stop it, nor does waking it up from the app, or even walking towards it with my key(unlocking it). But as soon as I open the driver's side door(honestly have not checked any of the other doors), it will stop. Battery is at 74%.
Car is a 2018 S75D, with almost 29K miles. It does seem to have a small battery drain associated with it, maybe 1 mile per hour according to Teslafi. Teslafi also shows the car is not sleeping during this period.

This is the coolant pump running. It's been discussed here in other posts. Basically from what people are saying, anytime the car is sitting with a state of charge > 80%, the pump will run for extended periods. This started happening with one of the more recent (2019) firmware updates.

This is allegedly (unconfirmed) a preventative measure intended to maintain battery health and prevent thermal issues.

It is "normal".

the headlights can also emit a high pitched whine

My state of charge was less than 80%, it was would have started at 78%.

A 'high-pitched whine', hm? Are you sure your teenaged daughter isn't in the car, not allowed to drive?
