Audi brake booster vacuum hose, genuine OEM part 80A611931AG (also replaces 80A611931P). This used vacuum line connects the brake booster to the engine's intake manifold on EA888 2.0 TSI/TFSI engines found in Q5, Q5 PHEV, and Q5 Sportback models. If the hose develops a crack or leak, you’ll likely notice a hard brake pedal and reduced power-brake assist—a direct symptom of lost vacuum.
