The Audi S4 coolant return pipe (OEM 8E0819373H) is a used genuine component from a donor vehicle. This line routes coolant back to the engine block or radiator after it passes through the heater core or other systems. A cracked or leaking return pipe can cause coolant loss, overheating, or steam from the engine bay, so inspection for corrosion or damage is wise before installation.
