My Audi was running strong. I threw a check engine light which said it was 16395/p0011. I drove the car home, let it sit for a couple hours. Went back out and the car wouldn't start.

It would chime and the lights would all come on, but when I turned the key all I got was 1 click sound and nothing else. I tried to jump it and still got nothing.

Any ideas where I should check next?
