The rear axle differential from a 2019 Audi A6 Quattro, OEM part number 09R500043B, is a genuine used unit removed from a donor vehicle. Also known as the diff or rear differential, it transfers engine torque to the rear wheels while allowing each wheel to rotate at different speeds during turns. On this 3.0L V6 MHEV turbo model, a failing diff often produces a howling noise, vibration, or fluid leaks from the housing.
