Hello,
I have a 2002 a4 1.8T. Currently, the car does nothing when I turn the key. No crank, no noises. The strange thing is that the battery stays on, even when the key is not in the ignition. If they key is out of the ignition, the cluster lights stay on, the windows work, lights, heat, radio, everything. I've disconnected the battery, and when I reconnect it, everything instantly turns back on again. Have you ever heard of this happening? Any help would be greatly appreciated. Thank you.
