This Audi 4H0317818M transmission oil cooler line / pipe (supply) is a used genuine OEM part, removed from a donor vehicle. The supply line circulates transmission fluid to the cooler; when it fails, leaks can cause low fluid pressure and potential transmission overheating. It fits Audi A8 Quattro and S8 models with several engine options including the 3.0L V6 diesel, 3.0L supercharged V6, 4.0L turbo V8, and 6.3L W12.
