Known issues on the 2005 A3. One recall is on federal record for this model year, issued alongside the related Volkswagen Passat and Audi A4 Cabriolet, covering the driver's frontal air bag inflator module: in a crash serious enough to trigger deployment, excessive internal pressure can cause the inflator to rupture and send metal fragments toward the driver or other occupants, risking serious injury or death. The factory diagnostic and repair procedures behind that system are here.

Whether you're inspecting the airbag system after this recall or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2005 A3.
