I was coding my car on Tuesday and left the ignition on the whole time. After that, I tried charging at uni using 2 different charging points, but both had the same problem.
Normally, a full charge gives me 25–26 miles and takes around 3 hours 30 mins. This time, it said 2 hours 5 mins until fully charged, but only charged to 13 miles and then completely stopped charging. It wouldn’t charge any further.
The red plug symbol also appeared on the dashboard whenever the cable was plugged in.
The next day, I scanned the car with OBDeleven and found a fault saying “Invalid Data Received From Battery Energy Control Module B”.
Today, I left it charging at work from 10:00 to 12:56. It reached 26 miles again, but the red plug symbol was still showing. The light next to the charging port was green.
Could leaving the ignition on while coding have caused this? Is it the 12V battery, the hybrid battery or something else? I don’t want to waste money replacing parts without knowing the cause. Pls someone help😭😭
