Hello.
When you open the door with the Tesla unlocked, the prunk makes a ping~ sound.

When the screen is on and the door is opened (in the driver's seat), there is no sound.

And run the Tesla app, it sounds the same.

I wonder if it sounds normal.

Is it the sound of the screen turning on or the parts working?

Thanks!!!
