Product Details

Bosch Premium Alternators are engineered, assembled, and tested for consistent performance and reliability in everyday driving conditions. This remanufactured alternator uses an internal regulator, internal fan, and a 6-groove pulley with a 61 mm outside diameter. The AL0193X is designed for vehicles that call for a clockwise-rotating, 140 amp charging unit, making it a strong match for Volkswagen electrical system service where OE-style fitment matters. This part number, AL0193X, is also referenced by OE number 06K903023 for the same application.

Compatible With 2013-2014 Volkswagen Jetta, 2013-2014 Volkswagen Beetle, 2014-2017 Volkswagen Passat, and 2014-2016 Volkswagen Beetle, with additional 2015 Volkswagen Beetle, 2015 Volkswagen Jetta, and 2015 Volkswagen Passat coverage for specific 140 amp Bosch-unit applications. The Bosch AL0193X is a practical replacement when the original alternator no longer maintains proper charging output.

Installation Notes and Tips

Verify pulley style, 6-groove belt alignment, amperage rating, rotation direction, and connector fit before installation. Confirm the vehicle uses a Bosch unit and matches the listed year and model coverage, especially on 2015 applications with date-specific fitment notes. Inspect the drive belt, tensioner, battery condition, and charging cables during replacement to help prevent repeat charging-system faults.
