the language changes by itself

Hello, i have 1/2018 model s 75D with mcu1. I left car for 5 days at airport parking lot, soc was 70%. When i get back to car, the language was changed to netherlands. Car is imported year ago from netherland. Everything else was fine and normal. Is my 12v battery bad or is it mcu1 bad? I changed language back to finland and its been working since.

When you said it was parked at the airport…was it under the flight path of KLM ?

No, it was small local airport. Only finnish aircraft
