A used genuine OEM Audi coolant hose/line set, part number 8W0122445C. This set serves as the factory replacement for the engine cooling system on 2.0L turbocharged four-cylinder applications, including both flex-fuel and gas variants. A common failure point is a cracked or leaking hose at the connection to the coolant reservoir or thermostat housing, which can cause coolant loss and overheating. This set includes all necessary lines for a complete, direct replacement.
