Bosch Remanufactured Alternator for BMW

Bosch AL0841X is a remanufactured 12-volt alternator built for charging-system performance and dependable electrical output. It is engineered for BMW applications that require a 155-amp unit with a 6-groove pulley and internal fan design.

The Bosch Premium Alternators line focuses on remanufactured charging components that are built and tested for consistent operation. This AL0841X alternator uses an aluminum case, clockwise rotation, internal regulator, and a pulley included from the factory for direct replacement service.

Detailed Description

Bosch AL0841X is a remanufactured alternator for BMW charging-system repair where stable voltage delivery matters. It is listed for 2007-2013 BMW 128i, 2007-2013 BMW 328i, 2009-2013 BMW 328i xDrive, 2008-2010 BMW 528i, 2009-2010 BMW 528i xDrive, 2007-2010 BMW X3, 2007-2010 BMW X5 without rear A/C, 2008-2009 BMW 323i, 2007-2008 BMW 328xi, 2008 BMW 528xi, and 2007 BMW 323i from 04/2007. This part cross-references Bosch OE-style BMW applications using part numbers 12317551256 and 12317555926 for the same application.

What It Helps Fix

  • Battery warning light caused by weak charging output
  • Low system voltage during driving or idle
  • Dim lights and inconsistent electrical performance
  • Charging failure from a worn alternator assembly
  • Accessory and starting issues related to insufficient alternator output

Installation Notes

Verify the vehicle’s alternator amperage requirement before installation, since several listed BMW applications note use up to a 180-amp alternator. Confirm plug type 463, clockwise rotation, 6-groove belt alignment, and the rear mounting ear orientation before fitting. This alternator is not one-wire capable.

Quality Assurance

Bosch Premium Alternators are remanufactured, built, and tested to meet charging-system performance and reliability expectations for service replacement use.
