My servo pump or should I say PAS pump is making a terrible noice when it is cold, propably the bearing. When the engine is warm the noice is allmost gone. Well anyway I got a PAS pump from a UrS4 but my question is that does it fit on a RS2. Does it have the specs with pressure and so on.

I have changed the pump and it was just bolt on. The first time I started the engine, pump was really quiet. Know a few weeks after the noise has come back but the warning light (!) hasen't appeard yet. Yesterday I wanted to get rid of the problem and a friend of mine checked the fluid tank when I started the engine. The pump was moaning like never before and I started to turn the steering wheel from side to side, and what happened, yes the noise disappeared and a lot of air bubbles came in the fluid reservoir. I checked all the lines and found a place where I could see a small leakage.
Next thing is to renew all rubber hoses and I will report if that helped anything.
