Audi Brake Booster Vacuum Line / Hose, OEM 4F0611931CF, is a genuine used part from a donor vehicle. This line also replaces 4F0611931BK, 4F0611931AT, and 4F0611931AK. Fitted to 3.2L V6 naturally aspirated engines in Audi A6 and A6 Quattro, it supplies vacuum to the brake booster for power-assisted braking. A cracked or leaking line here often causes a stiff brake pedal or diminished assist, making inspection worthwhile during brake service.
