Known issues on the 1992 V8 Quattro. Two recalls are on federal record for this model year. The first covers the rear speaker amplifiers: an electrolytic capacitor inside each unit can leak electrolyte that, combined with humidity, creates an unwanted conductive path and a potential fire risk. The second covers the front air bag sensors, which fell short of Audi's durability standards and, if they malfunction, can trigger inadvertent air bag deployment and cause a driver to lose control. Owners have filed 1 complaint for the year. The factory diagnostic and repair procedures behind both of those systems are here.

Whether you're tracing a stereo wiring fault or inspecting the air bag sensor circuit, it keeps you on the OEM procedure for your specific 1992 V8 Quattro.
