Known issues on the 2009 A3 Quattro. Five recalls are on federal record for this model year. Two separate campaigns cover the driver's frontal air bag inflator module, which can build excessive internal pressure and rupture or explode, sending metal fragments toward vehicle occupants during deployment. A third covers the ABS/traction control unit, which can fail during ABS or Electronic Stability Control activation and cause a loss of vehicle control. A fourth covers the automatic transmission, where insufficiently crimped wiring at a temperature sensor can cause a false high-temperature reading and an abrupt, unannounced shift to neutral. A fifth covers the fuel tank ventilation valve, whose internal spring may not hold closed under extreme driving conditions, allowing fuel to leak in the presence of an ignition source. Owners have filed 47 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From an air bag inflator inspection to chasing an abrupt neutral shift or a fuel tank ventilation check, it keeps you on the OEM procedure and the correct specification for your specific 2009 A3 Quattro.
