Sudden GID/SOH drop

Hi everyone,

I have a '15 SV bought in July '14, now 45k km.
I had 293 Gids at delivery and maintained that level (292-293) until 1 month ago.
I took my LEAF to the dealer last month for the 2nd year (free) battery check.
They also performed the passenger airbag sensor recall.

Since then, I realized that my LEAF will top-off at 280-282 Gids...
LeafSpy reported SOH=99%, now its down to 95-96%.

That's a drop of 10 Gids in less than 1 month... WTF?
It's a bit cooler here than 1 month ago, but that does not explain a drop like this..
Someone knows if Nissan can reprogram the BMS as part of regular maintenance?
Any thaughts on that sudden drop?

Thanks!

I'm guessing that the lower temperatures generate lower Gids. Do a search in some of the technical threads and I think you'll find that Gids are not always created equal.
