My Headlights, AC, Heat, Blinkers & Wipers ALL went out at the same time. My brights, hazards, break lights & radio still work. Fuses appear to be okay, and I replaced the relay located in steering column but no avail. My local Audi dealer couldn't give me a definite answer either. Also, at the same time my dash display for PRND234 began lighting up in "safe fail mode" causing the car not to shift. If I put my foot to the floor on the gas pedal it just gradually gains speed but never shifts. Sometimes if I turn the car off and back on then it will go back to normal and the dash display is not lit up however while I'm driving, at any point it will kick into the safe fail mode, jerk harshly, then the gear display will light up solid. Could these all be linked to some sort of electrical issue? Thanks for your help.
