Audi Brake Booster Vacuum Hose / Line OEM 8W0611931CD — a used genuine part pulled from a donor vehicle. This hose, also known as the brake booster vacuum line, supplies engine vacuum to the booster for power-assisted braking. Interchange numbers include the 8W0611931BR, 8W0611931BT, 8W0611931BH, and 8W0611931BC variants. Engine application: 2.0L turbocharged EA888 Gen 3/3B in Audi A4 and A5 models. A cracked or leaking hose can cause a hard brake pedal, reduced assist, or a hissing vacuum leak under braking.
