Hi, It was -6c the other night and despite my car being garaged overnight, when I started it in the morning I got the following message on the DIS - "BATTERY LOW CHARGE - WILL CHARGE WHEN DRIVING".

I wasn't too concerned at first. Then I did a 40mile motorway journey, switched off and re-started but the message came up again, and I now get it every single time I start the car.

Has anbody else had this ? does it sound like a duff battery and if so is it under warranty ? I've only had the car 6 weeks and it supposedly had the full 130ish point check.
