A used genuine OEM Audi brake booster vacuum hose / line, part number 4M0611931BG, from a donor vehicle. This vacuum line supplies the brake booster with engine vacuum for proper power-assist braking. On the 4.0L V8 mild-hybrid turbo engine found in the RS Q8 and SQ8, a failing hose can cause a hard brake pedal or reduced braking assist.
