Audi=No fault code, no idea
Hmmmm, really intestine one this. The oil returns are mostly low pressure and i would imagine there would only be a couple of high pressure feeds up the block where the water jacket is. In 90% of places the water pressure would be much higher than the oil pressure so i would expect to see water in the oil, not oil in the water. Need to put my thinking cap on for a while...........
