A used OEM Transmission Oil Cooler Line / Pipe, Audi part 4B0317818C, is a direct-fit replacement for the 2.7L 2671CC V6 DOHC turbocharged engine found in the A6 and Allroad Quattro. This pipe also supersedes 4B0317821C and 4B0317821H. It carries hot transmission fluid to the cooler and back; common failure modes include cracked unions or corrosion at the metal line, leading to fluid leaks and slipping.
Line goes from transmission to another cooler line. Eventually to the secondary oil cooler.
