Known issues on the 2003 A4. Four recalls are on federal record for this model year. The first covers an aftermarket water pump: a timing belt failure from the affected part can cause the engine to shut down, increasing crash risk. The second covers xenon headlamps, where the lens coating can degrade over time and reduce light output, affecting the driver's field of view. The third and fourth both cover the fuel pump on vehicles built with the 1.8L turbo, 2.8L V6, or 3.0L engines: a change in the pump's electrical motor components can leave fuel flow interrupted, causing the vehicle to stall without warning. Owners have filed 215 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From a stalling fuel pump to a headlamp inspection or a full timing belt service, it keeps you on the OEM procedure and the correct specification for your specific 2003 A4.
