This manual is built specifically for the 2000 Audi A4, covering the 1.8L turbocharged four-cylinder (engine code ATW) and the 2.8L naturally aspirated V6 (engine code ATQ), so the specifications, torque values, and repair sequences inside match what Audi actually published for your engine and trim rather than a generic A4-era approximation.

- 2.8L V6 — DOHC, naturally aspirated, gasoline
- 1.8L inline-four — DOHC, turbocharged, gasoline
Body styles covered
- 4-door sedan
- 4-door wagon
Trims covered

Known issues on the 2000 A4. Five recalls are on federal record for this model year. Two cover the driver-side front air bag inflator module: Non-Azide Driver air bag inflators lacking phase stabilized ammonium nitrate propellant can absorb moisture and deploy improperly in a crash, failing to properly protect the occupant. A third covers aftermarket Tru-Flow water pump replacement parts sold for this engine, where a defective unit can cause timing belt failure and engine shutdown while driving. The remaining two cover aftermarket replacement combination lamps sold without amber side reflectors, which fail federal lighting standards and reduce visibility to other drivers. Owners have filed 96 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 driver air bag inspection to a timing belt and water pump job or routine service on the ATW or ATQ engine, it keeps you on the OEM procedure and the correct specification for your specific 2000 A4.
