But today I realized that this only happens when LeafSpy is polling the car. If I exit LeafSpy, the chatter stops.
I'm a bit concerned that the LeafSpy polling could be shortening the life of some components in the car, specifically the relays which I assume to be making this noise. Has anyone else noticed this? Turbo3, any idea which parts of the polling may be causing this?
I tried to replicate your issue with my 2012 Leaf. What I hear is a very slight "crackling" noise that appears to be coming from the junction box. It happens while charging whether or not I have the OBDII dongle in place - and of course having LeafSpy on/off makes no difference (always makes the noise when charging). I have the LELINK (low energy bluetooth/iOS) dongle. What operating system is your LeafSpy app?
I leave my dongle in place always and have not had any 12v battery drain issues when gone over a week - with the original battery.
2012 Leaf SL; 46,000 miles. Battery replaced November 1st, 2016.
