I bought a used Leaf almost year ago and, aside from charging timer malfunction, it has been ok in general.
However, few days ago it started humming. When charging, when driving, whenever I turn it on or give the beast some electricity it just spins up his fans and keeps at it until I switch it off or take electricity away. Granted, last few weeks weather has been warmer (20-30 C days, <20 nights) but it feels over excessive IMO.
Battery temperature, usually is around 5-6 bars (maybe 4 at night), last time I checked in the middle of the day with LeafSpy and it was 20-22 C. I cover 100km every day, charge with 220V every night.
No errors that I could see, nothing. Just humming.
Any experience? I've booked a meeting with my local service but is there anything I could snoop on my own? Does LeafSpy show up errors or I need to get separate OBD diagnostics dongle as well?
Anyways, thanks in advance!
