Hi Kirsty, I just went into my local Nissan dealer and asked them to do a (free) 100 point check and to check whether the updates had been done.Thank you- how do I check the BMS upgrade?
I mentioned the BMS upgrade in particular and also that it should increase the displayed SOH and range, so that they knew what to look for.
I can't find the reference No. for this, but it's called "LI-ION Battery Controller" upgrade on my paperwork.
I think I've seen a ref No. somewhere else on this site so someone may be able to help with that.
It should give about a 4% increase in SOH (mine did).
