Update
I have successfully reset the BMU with the D easy method.
Fully charged shows 66km range on GOM.
Yet to test out.
Update.
I took the car out for a drive. Where I live is quite hilly. Ended up with 42 real km. No ICE.
No I don't have a OBD2 just yet.
Ok so I tried the D-easy and the D method. I don't see any change except the GOM got reset. So I tried the A-method, with a twist. Instead of a depleted car battery, I used variable power supply. The power supply is capable of 10A. I tried from 8.2V, that was not enough for the relays to come...
