Thank you for the reply, the car has only done 34,000 miles and I haven't driven it properly in about a month so it could be a low charge, I did turn of the heat, auto headlights and no music, I also prefer to turn the Stop Start off anyway and when I stopped my journey for today and let the car idle the battery charge sign didn't come back on. So hopefully I can't complete my journey and get it checked properly in the next service which is due very shortly
