This used Audi coolant pipe / tube / line (OEM 4E0121169A) came from a W12-powered A8 Quattro. It's the factory-formed metal or plastic coolant passage that routes antifreeze between engine components on the 6.0L W12. When this line cracks at the fittings or corrodes, expect slow coolant loss, a sweet smell, or overheating. Alternate names include coolant tube and coolant line.
