Hello,
I have the same problem as you for a few days.
Following the change of the 12v battery, the car will not restart, more current at all ...
For the history of sympthomas: Since a few weeks
more steering wheel controls and some more memorized settings
Week from 4 to 10 November
various trips / returns Cht / Nantes
the central screen does not launch; unable to access menus / settings; maximum temperature and ventilation; the rest works properly off put flying orders still hs
During the week of November 11 to 17
overnight, restarting, everything works properly, screen AND steering wheel controls
During the week of November 18 to 24
battery failure - Elisabeth can not open with the key
I plug the car on a mini charger on the + engine and a mass -> the next day the car starts ...
the day after, still flat; I buy a booster and the car restarts ...
Can someone point me to repair tracks to study?
Thank you in advance,
Nicolas.
