I have an 1995 Audi Avant A6 Q...V6 2.6 and I've replace the power steering line that goes directly up and to the top of the motor passenger side....After now replacing it twice(not an easy job) and making sure it is tightly bolted on both ends...it still leaks out dropping down on the exhaust manifold below causing the car to smoke in tern coming up inside the car(the smell at least)......Does anyone know why? or have they had a similar problem?

 

Usually when that happens the threads got crossed and no amount of tightening will stop the leak.
