Known issues on the 2015 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 first, a second impact to the front of the vehicle may fail to command the front air bags to deploy, raising the risk of occupant injury. Owners have filed 1 complaint for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind that system are here.
Whether you're inspecting the air bag control module or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2015 S4.
