Is it normal that the front fans are contiously running when charging at 13a/240v when charging after a drive ? even during cold weather. On 10a this never happens. i have a feeling that something is wrong with the HVAC... under which conditions do your front fans come on ? and how long do stay on ? roadster 2.5 2012 - - - Updated - - - I also noticed, that when I get in the car and turn it on for a very short while, the front fans stop and don't come on anymore during the rest of the charging cycle. If I don't do this, they'll remain on until charging has completed weird.
