What is this pipe that is weeping oil?
When I bought the car, Audi Bromley had left the oil cap off when I took it for a test drive, so the foam on the underside of the engine cover was soaked in oil. It's always weeped oil in the area pictured. I don't know if its from the pipe or dripping from the bottom of the engine cover, which I've cleaned numerous times. Should I be concerned about it?
P.S. Please excuse my dirty bay, but it's cold and wet outside
