I have a Audi a8 2004 and my car was off with the door open the battery died I tried giving it a boost and it wouldn't work what can I do??
I'm assuming it doesn't crank, sometimes those take more than what jumper cables will put out and if you're using a jumper pack that isn't fully charged it may not push enough to get it to turn over. Other possible cause could be a loose connection on the battery cables. Those are also common for instrument panel and ecm issues
