This Audi 059103688 Engine Oil Cooler Pipe / Line (return) is a used genuine OEM part removed from a donor vehicle. As the return line to the engine oil cooler, it routes hot oil back from the cooler to the engine—when this pipe cracks or its seals fail, it can cause visible oil leaks and low oil pressure. Fits the 3.0L 2967cc V6 diesel (EA896 family).
