I am an owner of a Seat MII EV. I am concerned about the high amount of battery drain when I parked my car for 17 days. I left the car at around 80% SoC and returned with it being 40% SoC. The outside temp was around 0 – 11C. The only thing that was plugged in was the OBD reader for power cruise control. Any advice would be appreciated.

I suspect that the OBD device keeps the car awake.

The only thing I can think of is if the ECU in the car remained powered up. Was a light left on? There need to be more investigation into this…
