Audi Brake Booster Vacuum Hose / Line, OEM part number 4E1611931BN, is a used genuine part sourced from a donor vehicle. This hose, also known as a vacuum line, replaces 4E1611931AK. It is designed for the 4.2L V8 gas engines (both 4163CC and 4172CC) in the Audi A8 Quattro. A failing brake booster vacuum hose can cause a hard brake pedal or a hissing sound from the engine bay, indicating a vacuum leak that compromises braking assist.
