    Indeed, I doubt any dealership went thru with this not at all supersmooth operation.

    My value was more to show indirectly this model can hardly cope with 10 days of inactivity even at normal temperatures. Hence my battery and CTEK obsession is confirmed. Ctek does lack volt readings though, which is a good indication of capacity (24h after charging).
