Model Year 20/21 [Solved] 2 defaults : lane assist & park assist

[Datawolf]

Hello,

My alarm went off this afternoon (Sunday). The formentor's battery was empty. I charged it and went for a drive. The battery light has now disappeared (I have 14.6V running). However, 2 errors appeared: door detection and park assist.
The OBS gives me codes U112100 and U112300.
Can I expect them to go away once I've been driving longer? Or should I expect to have to replace the camera unit that includes the inside rearview mirror?
Also, why is my battery empty even though I drove on Monday and especially Wednesday?

Thanks in advance

The Datawolf

Additional bug occured: cannot increase the sound (=> muted).
And despite I used a battery charger, I got the day after a low battery message.
I was about to replace my battery (140€ ), but I decided to buy a smart charger first (20€ at Lidl.fr). And it brought my battery back to life !
Since I had to disconnect the battery from the car, a multitude of defects appeared, but they all disappeared by driving in less than 100m.
I'm thrilled!
