The Transmission Oil Cooler Pipe / Line (Supply), OEM part number 4N0317818L, is an essential component for maintaining optimal transmission temperatures within Audi Q8 (2019-2022) and A8 Quattro models (2019-2021). Located between the transmission and the oil cooler, it efficiently carries transmission fluid, helping to prevent overheating during operation. Common signs of wear or damage include leaks or insufficient fluid flow, which can lead to transmission failure. Also referred to as the oil inlet tube, this pipe is crucial for performance, especially in high-load situations. It is compatible with select 3.0L V6 and 4.0L V8 engine configurations. Ensure reliable operation and restore your vehicle’s functionality with this factory-original part from a salvage operation.
