I encountered the same problem. It didn't take me long to figure it out. A friend of mine is in the car repair and maintenance business. I called him and he told me that in BMW cars it is everywhere. One in five owners experience it. That's the way the electronics work for that manufacturer. More precisely, it works, but there's a lot of it. This is why there are all sorts of glitches. In our country, unfortunately, it is also a glitch, there is nothing to repair in principle. Since the car is fully operational. It needs to be re-flashed. But it is not clear how long it will help. Maybe in a month or a year again the same thing. He advised me to buy a small device in the OBD connector. I bought it from the guys at https://ecutools.eu/. You can also find it in other stores. I just trust them, that's why I advise them. Read the errors, reset them all and you're good to go. Car's as good as new. No need to go anywhere. But I do it once every two months. But it's all free.

First of all it depends on what kind of error on the dashboard.
