my car won’t start, but i’m not sure if it’s just the battery. I turn my keys and it won’t do anything. Its an Audi A4 2007.


Battery is the first place to start. Without a good charged battery the rest of the vehicle isn’t doing anything.

It is possible that the battery terminal ends are loose or corroded.
