I opened the trunk by key two days ago. After that I wanted to close it again by button. I couldn’t. I put myself in the car and pressed the start button. Then the light show went off. Unfortunately I didn’t film. There was “Bremsassistent…..”m 12V-Ondernetz……”, “Don’t tow carts”, “Find a workshop”, “High-voltage system…..”, etc. Everything with a funny mold in the driver’s display. I then could close the trunk by various actions. If I have locked up or not, I don’t know any more. Close after an hour. Close up, start again error messages. Lock the car again. Put the key down overnight and wait. The next day at noon there was no error message. Wednesday the vehicle goes to the workshop. I’m curious what the fault memory and the customer service master says about it. It’s not really trusting.
