G'day,

I bought an audi A3 in 4 months ago, i had the battery replaced 2 months ago because it was 5 years old and was flat. My car has been running fine, ive left it 2.5 weeks and started it up and it has been fine. I've always left the lights in automatic mode (so they switch on/off when needed). I recently went away and when turning off the ignition the lights warning appeared (that beeping noise) and the green display in the control panel. I switched the lights to the off mode (ie not automatic anymore) and the noise stopped but then 2 days later my battery was dead. I got it charged from a friend and drove it for a night and 2 days later it is dead again, the battery is completly dead, i have to open with the key and not the automatic unlock system.

I'm pretty bad when it comes to cars but does anyone have any ideas on what i've left on or is it going to be some kind of eletrical problem?

Thanks for your tip
