Known issues on the 2009 S4. Two recalls are on federal record for this model year, both tied to the passenger frontal air bag inflator module: the propellant can degrade over time and cause the inflator to explode or rupture, sending sharp metal fragments toward the driver and other occupants and risking serious injury or death.

Whether you're inspecting the passenger air bag module or working through the V8's routine service intervals, this manual keeps you on the OEM spec for your specific 2009 S4 Cabriolet.
