Dear Users, I had this problem yesterday:
The car is Volkswagen Touran 1.9 diesel, manufactured in 2004. The temperature and fuel level indicators do not drop to zero, even after disconnecting the battery.
After turning the key, they drop to zero and go up again, while the clock, radio, etc. settings are reset (as with disconnecting the battery). After a while, everything turns on again and the car starts without any problems.
I recorded a video of how it looks like: https://www.youtube.com/watch?v=e5PikjY9sWQ
