The driver's door lock on my 1990 90Q20V also broke: key just goes around in the cylinder, the door handle of course works fine. That's why Audi put the (nearly) same feature for central locking on the pasenger's side! I haven't fixed it yet; my passengers' always assume I'm just a very chivalrous person.
