The Story
Remanufactured Alternator for Mercedes-Benz AMG
MPA Electrical Part Number 11303 is a remanufactured 12-volt alternator built for OE fit, form, and function. It is engineered for Mercedes-Benz AMG charging systems that require a Bosch-family unit with a 6-groove serpentine pulley and internal voltage regulation.
This remanufactured alternator is a direct replacement for select Mercedes-Benz C63 AMG, E63 AMG, CLS63 AMG, ML63 AMG, SL63 AMG, CLK63 AMG, and R63 AMG applications. Part number 11303 is tested using current remanufacturing and validation methods to support consistent charging performance.
Key Features
- 12.0-volt alternator with 180.0 amp output
- Internal fan design for integrated cooling
- Clockwise rotation, right-hand direction
- Internal regulator type
- 6-groove pulley for serpentine belt systems
- Pulley included
- Bosch family design
- Decoupled or clutch pulley: No
Detailed Product Information
MPA Electrical 11303 is a remanufactured alternator for Mercedes-Benz AMG vehicles that use a Bosch-style charging system. The unit is built to match OE fitment requirements and restore proper electrical output in high-demand performance applications. It cross-references 156 154 01 02 for the same application.
Compatible With 2008-2015 Mercedes-Benz C63 AMG, 2009-2012 Mercedes-Benz SL63 AMG, 2007-2011 Mercedes-Benz CLS63 AMG, 2007-2011 Mercedes-Benz E63 AMG, 2007-2011 Mercedes-Benz ML63 AMG, 2007-2009 Mercedes-Benz CLK63 AMG, and 2007 Mercedes-Benz R63 AMG. The part number 11303 is a practical OE-style replacement for vehicles that need a 180-amp charging solution.
What This Alternator Helps Address
- Low charging output from a worn alternator
- Battery warning lights related to charging system faults
- Dim lights or unstable electrical performance
- Battery drain caused by alternator failure
- Noise or belt-drive issues tied to a failing pulley or bearing assembly
Installation Notes and Tips
Verify pulley groove count, belt type, rotation direction, plug clocking, and mounting-ear orientation before installation. This unit uses a rear-view main mounting ear position at 6 o’clock, an internal regulator, and a serpentine belt pulley setup. Confirm vehicle-specific charging-system requirements on the Mercedes-Benz AMG application before final fitment.
Quality Assurance
As a remanufactured MPA Electrical alternator, this unit is processed and tested to support OE-style replacement performance. The remanufacturing approach is intended to provide consistent fitment and electrical output for select Mercedes-Benz AMG charging systems.
