I've not read the whole thread, but just noticed your car is 2018 Rene.
If it's still on the original Banner battery at 7+ years old it will definitely have lost some capacity and may well be about to fail completely

;-) the plywoodracer has got his third battery in one of the first steps to cure the problem.
Greets René
