The Audi A4 alternator keeps the battery charged and powers the car's electrical systems while the engine runs. This is a used, air-cooled unit with a serpentine pulley and an internal regulator, bench checked for output and condition. Output is typically in the 90A to 180A range depending on the engine and equipment.
Fitment matters here: A4 alternators differ by engine, such as the 1.8T four-cylinder versus the 2.8 V6, and the output and pulley can vary. The live page listed a 1994 donor year, but the A4 reached the US market for the 1996 model year (it replaced the Audi 80), so confirm your exact year and engine by VIN before ordering.
