A used OEM Audi Power Steering Return Hose / Line (part number 8K0422891AQ) for the 4.2L V8 in a donor Audi S5. This genuine line returns fluid from the steering rack to the pump reservoir. Over time, the rubber hose can crack or the metal line corrode, leading to fluid leaks, low steering assist, and increased steering effort. Replace a failing unit to restore proper hydraulic pressure and steering response.
