This is a used genuine OEM Audi heater coolant hose / line (outlet), part number 8W1819373C, removed from a donor vehicle. This outlet hose carries hot coolant from the engine block to the heater core for cabin heating. It fits 2.0L turbocharged four-cylinder engines, including the EA888 2.0 TFSI/TFSI variants. A common failure on these hoses is cracking or leaking at the plastic connector, causing coolant loss and interior heat issues.
