The battery on our 2016 Golf GTE was working perfectly but I started to have warning lights to say that the 12v battery was low and then needed to be replaced.
I had charged the battery and it was maintaining charge perfectly but still the problem persisted.
It turns out that there is a battery replacement 'count down' a bit like a service reminder. This can be accessed through VCDS or other ODB2 readers and either turned off or reset.
So far the warning light has not come back on.
In this video I also show you where the jump start / charging points are on a MK7 Golf GTE.
Good luck!
