Known issues on the 2012 A3 Quattro. Four recalls are on federal record for this model year. Three separate campaigns cover the driver's frontal air bag inflator module, where excessive internal pressure can cause the inflator to explode or rupture, sending metal fragments into the driver or other occupants during a crash. The fourth covers the diesel fuel system: injector line number 2 can develop small cracks from resonance under specific load and RPM conditions, and leaking fuel near an ignition source can lead to a fire. Owners have filed 43 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From an air bag inflator inspection to a fuel injector line check or routine service, it keeps you on the OEM procedure and the correct specification for your specific 2012 A3 Quattro.
