2009 Audi S6

On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, could eventually degrade the propellant contained in the passenger frontal airbag. This could cause the airbag to deploy with more force than normal. As a result, if the vehicle were involved in a collision that warrants airbag deployment, fragments could be propelled toward vehicle occupants, and the airbag assembly could be damaged, preventing proper function. These issues could increase the risk of injury. Correction: Dealers will replace the passenger frontal airbag inflator. Note: Canadian climate results in the propellant degrading slowly. The recall is being conducted as a precaution to address future risk, and is expected to replace airbag inflators before their function would be affected. Additional Note: This recall supersedes recalls 2016-266 (Audi Recall 69O2), 2017-026 (Audi Recall 69P6) and 2018-022 (Audi Recall 69U1). Vehicles completed under the previous recalls require repair under this recall, as the previous recall remedy was an interim repair. Interim repair parts must be replaced with final repair parts. Additional Note: For the 2009 model year A4 and S4 models, only the Cabriolet versions are involved in this campaign.
