Compatible with Audi A4, Audi A6, Audi Cabriolet, Audi 90, Audi 100, and Volkswagen Passat applications listed below, this alternator supports vehicles that use a serpentine belt drive and clockwise rotation. Part number 13357N is also a fitment match for several Bosch cross-reference numbers used in the same application.

Key Features

• 120-amp output for modern electrical load demands
• 100% new construction, not remanufactured
• Internal voltage regulator for integrated control
• Internal fan design for compact packaging
• Includes pulley with 6-groove serpentine belt configuration
• Clockwise rotation, right-hand rotation specification

Detailed Description

WAI 13357N is engineered as a Bosch-family alternator for vehicles that require stable charging performance and the correct pulley and rotation setup. The unit uses an internal regulator, internal fan, and 6-groove serpentine pulley to match the electrical and mechanical requirements of the listed Audi and Volkswagen applications. If you are replacing a Bosch-style alternator on an Audi A4, Audi A6, or Volkswagen Passat, this part number provides the specified 120-amp output in a new-unit design.

This part cross-references Bosch numbers such as 0 120 465 007 and 0 123 510 061 for the same application. Part number 13357N is used across multiple Bosch-equipped fitments, including Audi A4, Audi A6, Audi Cabriolet, Audi 90, Audi 100, and Volkswagen Passat models shown in the fitment table.

What It Helps Address

• Low charging output from a worn alternator
• Battery warning lights caused by charging system faults
• Dim lights or unstable electrical performance
• Accessory power issues under electrical load
• Noise or belt-drive concerns tied to alternator replacement

Installation Notes

Verify Bosch-family fitment, chassis breakpoints, and production notes before installation. Confirm pulley style, belt type, rotation direction, and amperage rating against the original unit before swapping in part number 13357N. This alternator is listed for N/A position applications and should be matched to the exact vehicle configuration shown in the fitment data.
