I'm just reading this as I have same problem. I have Audi A3 Quattro 3.2 petrol. Draining the battery completely. Same as this, boot lock was doing it to begin with. Fixed that and been ok for a few months now draining again....Flat..... Taken every fuse out, disconnected every gadget, light, wire, you name it. The only thing we did have was the central locking jammed once and another time locked the car whilst it was running with keys in the ignition. But we have tried disconnecting central locking. Any ideas apart from all the normal checks
