Known issues on the 2004 A4. Three recalls are on federal record for this model year. The first covers the front passenger frontal air bag inflator module, where an inflator rupture can send metal fragments into the vehicle occupants, resulting in serious injury or death. The second involves aftermarket water pumps installed on the engine, where a timing belt failure can cause the engine to shut down, increasing the risk of a crash. The third covers the xenon headlights, whose coating can degrade over time and reduce a driver's field of view, increasing the risk of a crash. Owners have filed 189 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
Whether you're inspecting the air bag inflator, replacing a timing belt and water pump, or checking headlight output, it keeps you on the OEM procedure and correct specification for your specific 2004 A4.
