The Audi brake booster vacuum hose / line, OEM part number 8W0611931CR, is a used genuine component sourced from a donor vehicle. This hose also supersedes several earlier revisions including 8W0611931CK, 8W0611931CD, and 8W0611931BR among others. Designed for select 2.0L turbocharged and mild-hybrid (MHEV) engines, it connects the brake booster to the engine vacuum source. A failing hose can cause a hard brake pedal or loss of brake assist, compromising stopping power. Replace a cracked or collapsed line to restore proper brake feel and safety.
