03' A4 avant 3.0 I had a small power steering leak somewhere, and about once every month or two I had to put a little bit more ps fluid in to stop the groaning. Pretty sure I was using the right stuff--11S. Then a couple weeks ago, I put some more in, and next thing I noticed it was shooting it back out of the reservoir cap.
I took the reservoir off and inspected it the best I could, all the ports seemed functional. When I put it back together, it just bubbles and splashes out of the top. And when I put more ps fluid in, the power steering works fine and is quiet, but it still shoots out of the cap, and starts groaning again when it gets low on ps fluid. I have talked to 3 different shops and gotten 3 different answers..?%#
I also tried bleeding it..
I ordered a new pump last week, but then they emailed back and said they were out of stock. My question is should I start w replacing the ps pump? Or is it possible that it is not the pump? One guy from one Audi dealership said he had only seen this problem once before in 10 years, and it wasn't the pump..
What ta do? Where should I start?
And if you think it is the ps pump, can anyone send me a good DIY link for 03' 3.0 ? Thanks so much.
Now I think it is the pump, the return line, or the reservoir...?) In the small hose feeding into the filter, there are two hose clamps about 3 inches apart.. Doesn't show these in the Audi diagram. Maybe some kind of flow control? I read another post and a guy said he bought that new hose from the dealer and it didn't have one either...???
