Lance, first try a different battery. Also check the battery grounding cable, and of course both terminals and clean off any corrosion. Your battery should not have gone flat, unless the car had not been used for many months. A faulty or old battery will go flat by itself very quickly. There also may be an electrical issue with your A3, so get that checked out too. Good luck.

IMMO has static programming, it doesnt lose the ability unless the system has a fault, does the car start for 5 seconds then turn of by itself or not even start?

yes mate its starts for a couple of seconds then cuts out but if i try it a few times it is just blank cheers for help

That sounds like immo or key at fault, but need to get it scanned to ascertain the issue.

If it's not even cranking then it's certainly not an immobiliser issue. Probably starter motor if the battery is okay.

Then again, it seems like it's starting now, then cutting out....

When you turn ignition on but dont start the car, do you see a flashing yellow/red icon in the cluster?

How many keys do you have?
