A used genuine Audi transmission oil cooler line / pipe, OEM part number 8K0317818CN, is a direct replacement for the original equipment line removed from a donor vehicle. This line carries transmission fluid to and from the cooler, maintaining proper operating temperature for the gearbox. A failure in this pipe can cause fluid leaks, leading to slipping shifts or overheating. It fits the 3.0L supercharged V6 and 3.2L naturally aspirated V6 in the A5 Quattro, Q5, S4, and S5.
