    My q7 3.0 tdi.........is draining the battery,its ok if i go to it 12/13 hours later but after that its flat !

    Audi replaced it in may 2011 so its not 2 years old yet

    Have you checked the Battery is correct for your vehicle?
    You can check battery through vcds. See what voltage it is with ignition off/running. Any lights in boot turned on ?
