A used OEM Audi heater coolant supply hose / line, OEM part number 4G0819350B, also replaces 4G0819373B. This genuine hose carries hot coolant from the engine to the heater core for cabin heat. Over time, the rubber can crack or the molded end fittings leak, causing coolant loss and weak cabin heat. It fits 2.8L naturally aspirated and 3.0L supercharged V6 engines (common in C7-platform A6/A7).
