2006 Audi A4, battery charged, will only start with a jump
My 2006 A4 is stored in the winter; only driven in warm weather, take battery
out. Over the weekend, I put battery on the charger, charged to 100% and put
it back in. Car wouldn't start. Jumped it, started right up, drove it for about 45
minutes. Turned the car off. Wouldn't start. Ran like a charm - just won't start
on it's own. Any thoughts?
