Known issues on the 2003 A4 Quattro. Four recalls are on federal record for this model year. Two cover the fuel pump on vehicles with the 1.8L turbo, 2.8L V6, or 3.0L engines: a change in the pump's electrical motor components can leave it inoperative, cutting fuel supply and stalling the vehicle without warning. Another covers an aftermarket Tru-Flow water pump, part number TFW 41127, sold through certain NAPA Auto Parts locations or installed by service technicians, where a timing belt failure from the affected part could shut the engine down. The fourth covers xenon headlamp coating that can degrade over time, reducing luminous transmittance and a driver's field of view. 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 timing belt or water pump inspection, it keeps you on the OEM procedure and the correct specification for your specific 2003 A4 Quattro.
