Trims covered
- 20v
Known issues on the 1991 Coupe Quattro. One recall is on federal record for this model year, covering the front air bag sensor/control module: some sensors don't meet Audi's durability standard over the vehicle's life, and if a sensor malfunctions the air bag can deploy inadvertently, which could cause a driver to lose control. No complaints or technical service bulletins are logged for the year.
Whether you're inspecting the air bag sensor circuit or working through the 7A engine's regular service intervals, this manual covers the procedures and specs for this 1991 Coupe Quattro.
