Suddenly my power windows stopped working, the interior lights don't work, open door indicator on, but my doors are all closed and one last thing the flashing light near the door lock switch is not flashing anymore. I need some help because all of this just happpend at the same time. Could it be something to do with the fuses? Help please........

i would first guess that it is a fuse, so check it out. If thats not it then you might need an Audi mechanic to dig a little futher, we all know these cars are electrical nightmares.
