This used genuine OEM Audi Brake Booster Vacuum Hose / Line, part number 4E1611931S, was removed from a running donor. It connects the vacuum source to the brake booster, providing the pressure needed for power-assisted braking. A failing hose often causes a stiff brake pedal or a noticeable hissing sound under the hood. It's compatible with the 4.2L V8 and 6.0L W12 engines found in the Audi A8 Quattro.
