I have a '92 Quattro 100cs w/ a buzzer that comes on when key is turned on and only turns off when key is switched off. Also turns on if radio is turned on w/ ign off. Buzzer makes different noises for seatbelt and for key left in ignition. Not sure about door ajar tone don't seem to have one; so maybe that's the ticket. All switches seem to be in one piece, but maybe one is faulty? Just about ready to remove buzzer (if I can get to it). Thanks! :57:
