Known issues on the 2007 S4. Two recalls are on federal record for this model year, and both concern the passenger-side frontal air bag inflator module. The first involves an inflator that can explode from propellant degradation, sending sharp metal fragments toward the driver or other occupants and risking serious injury or death. The second involves a related inflator rupture that can throw metal fragments into the cabin with the same risk of serious injury or death. The factory diagnostic and repair procedures behind that air bag system are here.

Whether you're working the passenger air bag module or a routine service interval, it keeps you on Audi's OEM procedure and the correct specification for your specific 2007 S4.
