I am going to dig into the trunk(boot) and uncover that battery, to look for physical evidence of date codes etc, and I will ask my local garage to read into the VCDS settings this week. I did charge overnight, initially at 10amp rate for about 6 hours and then at 2 amp from 11pm onward. Letâs see if today it behaves any differently. It is to be hot today, up to 33c so about 90f. That should keep the AC and fans running and putting electrical load on.
I understand the theory of the vehicle battery management, and how it âprotectsâ the ability to keep reserve for starting, but have not experienced any of that happening to in-car systems shutting. In any case, I will report back with any final resolution activitiesâŚ
