This used OEM Audi coolant hose, part number 8K0121081CA, also supersedes 8K0121081BE. It’s a genuine factory coolant line, commonly called a coolant hose or coolant pipe. This hose carries engine coolant between components in the cooling system. A cracked or leaking hose can cause low coolant, overheating, or visible puddles under the car. It fits 1.8L and 2.0L turbocharged four-cylinder engines from the Audi A4 and A5 families.
