Possibly battery state of charge or battery temperature?On my Golf Mk8 GTE a circular display shows electric power on the left half and engine revs on the right half. Usally the blue electric power line goes all the way to the top (12 o’clock) but sometimes it doesn’t (around 11 o’clock). I assume there is less power available at the lower position but the reason for this seems to be a mystery. Can anyone help? Thanks in advance.
On my GTE when the battery is down to the last few miles the available electric power gradually drops from 100% to 75%.
Similarly when I left home yesterday with a cold but fully charged car the available electric power was around 80%, but after a couple of miles was back up to 100%.
