This genuine Audi coolant hose (OEM 4G0122449D) is a used factory line from a salvage donor. It serves the cooling system on the 3.0L V6 TDI (turbocharged diesel) engine found in the A6 and A7 Quattro. When this hose or line cracks or develops a pinhole leak, engine coolant escapes, leading to low coolant levels and potential overheating. Replacing it restores proper circulation to the engine and heating system.
