This used OEM Coolant Pipe/Tube/Line (part number 4E0121481A) was removed from a donor Audi A8 Quattro. Originally fitted to the 6.0L W12 engine, this genuine metal or reinforced line channels coolant between the engine and radiator. Over time, original pipes can corrode or crack, causing coolant loss, overheating, or visible drips beneath the vehicle. The part is also referred to as a coolant tube or line. A leaking coolant pipe left unaddressed can quickly lead to engine damage, so replacing it with this genuine used unit restores proper cooling system integrity.
