3rd time this year this happend, usually it's not there for months. Battery is few months old.
12V system is a pita on this 2012 Leaf.


Sounds like a buzzing relay.
I noticed you're still working with polymers.

Yes relais is first thing you hear. Fast forward to 1:43 voor the specific tone.

If you get to the root of the relay problem, the other tone may resolve.

The root of the problem is and always was/will be the "too carefull" charging of the 12V battery.
The buzzing relais as heard in that movie I made, went "magicly" away after a night on the charger. This is (apparantly) caused by a too low 12V battery. Which is strange because I drove the car the whole day as usual, with lots of starts and stops. Other symptoms are failing regeneration braking. There are lots of reports on this on this forum.
