Known issues on the 2013 S4. One recall is on federal record for this model year, covering the front air bags: an improper algorithm in the air bag control module means that if a crash triggers the side air bags, a second front impact may not command the front air bags to deploy, raising the risk of occupant injury. Owners have filed 33 complaints for the year. The factory diagnostic and repair procedures behind the air bag control system are here.

Whether you're inspecting the air bag control module or working through a routine service on the supercharged V6, it keeps you on the OEM procedure and the correct specification for your specific 2013 S4.
