B8 S4 Help Please!!!
 

I have a 2014 S4 Black Optic Package. I drained my battery on the car. I had the battery charged and everything electrical in the car functions properly, except the car won't start. When I attach a jumper cable under the hood, the car starts and drives properly, when I shut off the engine and try starting it again, it won't start. Is there possibly a wire or something that needs to be changed? Please help. Thanks

You need a new battery... mine died a year or two in... It's covered... Heck the dealer sent a guy out to my house and they installed the new one in my garage...

+1 these cars rely heavily on a fully functional battery and will let you know when they want a new one.
