Audi Coolant Vent Hose / Line, OEM part 06L121081AD, is a genuine used part removed from a donor vehicle. This hose, also known by superseded number 06L121081AC, routes coolant through the engine bay to release air from the cooling system. A failing vent hose can cause coolant loss, overheating, or air pockets that lead to poor heater performance. It fits 2.0L EA888 four-cylinder engines across Audi and Porsche applications, including turbocharged and hybrid variants.
