• Noise or wear from a failing alternator assembly
• Replacement for a Bosch 120 amp unit on listed Audi and Volkswagen vehicles

Installation Notes

Verify the vehicle’s original alternator specifications before installation, including amperage, pulley style, rotation, and connector layout. Because this unit is supplied without a pulley, transfer or match the correct vehicle pulley as required by the application. Confirm chassis breakpoints and optional equipment notes for 1997-1999 Audi A4, Audi A4 Quattro, and Volkswagen Passat models before ordering.
