Samsung SM-A516B/DS Galaxy A51 5G (using 4g only)
Kia E-Soul 2019
trip Perpignan to Nîmes airport April 2023. 100% correctly found via ODB2 before starting but soon dropped much faster than shown by car.
Return trip 3 weeks later idem: correct charge found at startup and again after charging 1/2 hour later but dropped much too fast during trip home.
Previous trip September 2022 worked fine 1150 km outward. Lost contact with ODB2 now and again during return but kept the correct charge %.
(I now have a problem with Android Auto not connecting so more difficult to use it)
Your car doesn't appear to be connected via OBD at the moment but I can see that it has been connected in the past and that you've got a calibrated reference consumption value.
Have you tried to connect it again? Or does the connection get dropped just?
What model of OBD device are you using for the connection?
