2006 a4 will not start.
The car was left for 3 weeks in 6-8 degree weather but would not start. Gave it a boost and she was fine drove for 10 minutes turned off but would not turn back on. Charged the battery and started it halfway through charging and it turned over no issues. When fully charged would not start but the remote works, windows, alarm, windows, lights, lock unlock etc. I am not sure whats left to try before mechanic or maybe replacing the battery?

Thanks for any direction and help

 

Replace the battery!!! A battery with a low charge can still run the lights,radio,remotes,etc.... But may not have enough power to start the car... Start there!!!!
