This used genuine Audi brake booster vacuum pipe, OEM 4H0611931AK, also supersedes 4H0611931H. This hose or line connects the brake booster to the engine’s vacuum source on the 4.0L V8 turbo engine (found in the A8 and S8). When it cracks or leaks, you’ll notice a hard brake pedal and reduced power assist—a common failure that can be diagnosed with a vacuum test. Replace only with the correct OEM pipe to ensure proper fit and sealing.
