This is phenomena which i see at my egolf2018 and now i saw at my friends egolf2019. Just situation, i come back to home, and i have only one schledule (at 6 pm) and i plug in clable, even that i pres timer button, it start to charge as without timer. The situation i solve, that i unblock plug, take it off and then back and in this case, start blinking and charging ate proper time in the midnight.
The same bad behaviour occured at my friends egolf2019 too.
I solve this phenomena, that i set first timer at evening with SOC 60% end and the second one timer is at morning at SOC 90% with heating, now in winter.
