Detailed Description

Remy 11157 is engineered as a remanufactured alternator for select 2013-2014 Audi A4, A4 allroad, A4 Quattro, A5, and A5 Quattro applications. The unit matches Bosch-based fitment requirements and uses an internal regulator to manage charging output within the vehicle electrical system. With 150 amps of rated output, it is suited to restoring proper alternator performance when the original unit is worn or no longer maintaining system voltage.

The clockwise rotation, internal fan design, and included pulley support correct mechanical and electrical replacement on the specified Audi platforms. Part number 11157 is also referenced by interchange numbers 0-125-711-051, 0-125-711-090, 06H-903-017J, and 06H-903-017T for the same application.

What It Helps Fix

• Low charging voltage
