Known issues on the 2006 S4. Two recalls are on federal record for this model year, both tied to the passenger frontal air bag inflator module: in each case, propellant degradation in the inflator can cause it to explode or rupture on deployment, sending sharp metal fragments into the driver or other occupants and risking serious injury or death. Owners have filed 30 complaints for the year. The factory diagnostic and repair procedures behind that air bag system are here.

From a passenger air bag module inspection to a routine V8 service interval, it keeps you on the OEM procedure and the correct specification for your specific 2006 S4.
