Known issues on the 1992 100 Quattro. Three recalls are on federal record for this model year. The first covers the brake vacuum booster pump, whose internal blades can wear prematurely and reduce brake assist pressure, increasing stopping distance. The second covers the rear speaker amplifiers, where a leaking capacitor can create an unwanted conductive path and raise the risk of overheating and fire. The third covers the frontal air bag sensor, which can fail to meet Audi's durability standards over the vehicle's lifetime and cause the air bag to deploy without warning. Owners have filed 23 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're bleeding the brake booster, tracing a rear speaker amplifier fault, or inspecting the air bag sensor, it keeps you on the OEM procedure for your specific 1992 100 Quattro.
