A4 2008 Audi wont start. Car wont turn over.
Drove car home from work with no problems. Went out an hour later and car
wont turn over to start. Battery is not dead. All lights on the dash work. Any
ideas? We hooked it up to an OBD but didn't see anything jump out at us
(We are amateurs). It also made a weird 2 second hum noise when we
turned the ignition on. with it still in the on position, the 2 second hum noise
came on again, not sure if this is related at all. maybe not? Can anyone
please give us some things to look at? Thank you very much -Teresa
