Detailed Description
This BBB Industries reman alternator, part number 42050, is engineered around OE-style charging specifications and the original Hitachi application reference. The unit includes a pulley and uses a decoupled clutch pulley design to help smooth belt-driven operation under changing engine speeds. With 180 amps, it is suited to vehicles that place a heavier load on the charging system.
Compatible with 2012 Audi A6 Quattro and 2012 Audi A7 Quattro, this alternator is a direct fit for those applications listed in the fitment data. The 2 o'clock plug clock position and clockwise rotation are important details for matching the electrical and mounting configuration on the vehicle. Part number 42050 is also cross-referenced to 06E-903-018G and LR1180-851 for the same application.
What It Is Used For
- Restoring charging output when the alternator is no longer maintaining system voltage
- Addressing battery warning lights caused by charging system faults
- Replacing a worn pulley or internal regulator assembly
- Correcting belt-drive issues related to alternator pulley wear
Installation Notes and Tips
Verify the plug clock position, pulley type, rotation direction, and amperage rating before installation. Confirm serpentine belt routing and electrical connector match the original unit. Use the vehicle’s listed fitment only; this part number 42050 is specified for the applications shown.
Quality Assurance
BBB Industries remanufactured charging components are built to meet application-specific requirements using OE reference data and remanufacturing processes suited to electrical replacement parts.
