High-frequency “fieping” after unlocking?

Hi guys, a question about my brand new Arona Style Edition with 116 hp: When I unlock the car in the underground garage by central locking, a high-frequency fieping starts in the front of the engine compartment. Always for a few seconds, then pause again. If it’s audible right now, however, it’s not consistently fieping, but sounds like someone is “mortizing” very quickly, i.e. it always interrupts unrhythmically. It goes towards coils as it is from power supplies or computers ke nnt, or even noise from computer boxes. You can only hear it in the quiet underground car park. I also have pretty good ears and hear any sound very well. I know that most cars whistle high-frequency for a while after opening or closing in some form, but am irritated that it sounds so “stitched” with me. Any ideas? Or just ignore? Many greetings Sushirunner
