This used genuine OEM Coolant Pipe / Tube / Line, part number 4H0121481AG, was removed from an Audi A8 Quattro. It carries coolant between engine components on the 3.0L supercharged V6 (2995cc). Over time, these plastic pipes can become brittle and crack, leading to coolant loss and potential overheating.
