Looking for a ODB adapter to leave plugged in that does not drain 12 V battery on my 2018 Leaf.
ODB-LX -> drained battery overnight. had to 'jump start' leaf to get car running.
Carista -> seemed to work fine for a a few days, then one day found 12 volt battery completely disabled -> had to use physical key to access vehicle and 'jump start' leaf to get it going. After unplugging the carista dongle,the issue did not repeat.
I have not yet tried KIWI 3 and LELINK^2 that state they support 'low power' features. Anyone has any experience with those?
Can anyone share any products that work on 2018 Leaf and allow ODB tool to be left plugged in? Is this even a thing? Can these dongles be safely left in the vehicle?
