Known issues on the 2002 A4 Quattro. Two recalls are on federal record for this model year. The first covers the front driver-side air bag inflator module: Non-Azide Driver Air Bag Inflators lacking phase-stabilized ammonium nitrate propellant can absorb moisture, causing the air bag to deploy improperly and increasing the risk of serious injury or death in a crash. The second covers the engine and engine cooling system: a failure of the timing belt tied to certain aftermarket water pumps can cause the engine to shut down, potentially 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.
From an air bag inflator inspection to a timing belt and water pump job or routine Quattro service, it keeps you on the OEM procedure and the correct specification for your specific 2002 A4 Quattro.
