Just a quick one ! I had the pre heat set to 7.20 and as it had been charging all night knew it would be fully charged so i went to turn it off/on to help fill the battery after pre heat had finished and to my joy heard the clicks/pops of the charging port that came on as the timer kicked in ! The charging light is also on . Another good point for the car ( which i can't fault as well as this forum ) happy new year
