ok so i have a problem with the power steering on my 01 audi s4 about a week ago i was in a drive thru and when i turned my wheel all the way to the left the power steering went out. came home looked at the top pressure line and it looked like the line was leaking from there replaced the line steering worked good 2 min the went out again the leak is still coming from the same location but cant tell exact where it is the fluid is all under the manifold and there is like 3 other lines there i have not pulled the manifold off yet to see what is there im thinking maybe a return line so my question is does any body know what other lines are in that location and if it helps any my tank is bubbling and when i turn my wheel it stops then builds up and i let go off the wheel it burst back into the tank.and one more thing i have noticed that the pressure lines that i see online are wrong this is what mine looks like thanks for the help sorry if i left any thing out
