This page covers one exact OEM part number. Every unit we stocked has sold.

The Transmission Oil Cooler Line / Pipe (OEM Part Number: 4E0317821M) is an essential component located within the engine compartment of the Audi A8 Quattro models from 2004 to 2010. This factory-original line facilitates the circulation of transmission fluid to the cooler, helping to maintain optimal operating temperatures for the transmission system. By efficiently transferring heat away from the fluid, it prevents overheating and potential damage to the transmission. Common issues that may necessitate replacement include wear, cracks, or leaks, which can lead to reduced transmission efficiency and shifting problems. As a critical part of the transmission system, this line interfaces with the transmission cooler and other fluid management systems, ensuring reliable performance. Replace a damaged oil cooler line promptly to maintain transmission longevity and functionality.
