A used genuine OEM Audi brake booster vacuum hose/line, part number 8W0611931BT. This hose carries vacuum from the engine to the brake booster, providing the assist needed for brake pedal effort. It also replaces 8W0611931BH and 8W0611931BC. Designed for 2.0L turbocharged four-cylinder engines (EA888 family). A cracked or collapsed hose can cause a hard brake pedal or a vacuum leak hiss.
