Update.....The car sat for a couple of days and you guessed it battery dead again, so this time I charged the battery with my mains charger for half an hour and then the wife and I went away for the weekend, drove the car for 150miles in the round trip,put the car back the garage when we got home (sunday) tryed to start the car on wednesday and the battery was dead. Car is booked into the dealers for monday morning...will let you know what they say when I get it back.Or if you have anything I should ask them please let me know.
