This used OEM Audi heater core coolant supply hose (OEM part number 4F1819342B) is also known as a heater core coolant supply line. It replaces earlier part 4F1819371B. This hose carries engine coolant to the heater core for cabin heat. A failing hose often leaks coolant, causing low heat or visible drips under the dash.
