    2001 A4 1.8t AWM: Can't get all the air out of power steering system

    Guest-only advertisement. Register or Log In now!
    Replaced power steering pressure and return lines on rack.
    Followed service manual procedure for purging.
    Basically it's jack up the front, lock to lock for a specific number of times.
    Then put back down, start up and do lock to lock again for a specific number of times.
    Go drive around.

    Well....been driving around for a few weeks, still get whine in the power steering system.

    What kind of experience have you folks had with doing this kind of work on the power steering system?
    Thoughts?

    I might be a little over full on the power steering reservoir, but likely by a few hairs if I remember correctly.
    Could that be preventing full purging of air from the system?

    Other then that, any other thoughts on what I could do to purge?

    You might just have a whining power steering pump.

    Do you see bubbles in the reservoir while turning lock to lock?

    It wasnt whining before I replaced the lines. Thinking about going through the bleed procedure again. Ill check then. I dont drive the car that often.

    Not simple ones, when I pretend to be an expert mechanic and talk about how I'm in the industry all the time.

    No need to be a jerk though, heís asking for help In the correct way.

    Try lifting the front wheels off the ground, full lock and hold 2-3 seconds back and forth, have someone watching the fluid reservoir for air. Repeat until no air/frothy fluid. Add fluid as needed.

    If a hose clamp is loose on the supply (between res and pump) the pump could be drawing in air from there.

    So report those posts.

    We're not here to be assholes to each other, we all share a common interest.

    Ok.

    If you have gone through the S.O.P.'s regarding servicing, perhaps looking at the pump being integrally damaged would be the next logical step.

    Just to throw it out there, in case it's at all relevant...

    I had continual issues with air in my S4's PS system about a year ago. Couldn't get it to bleed the air out, NO MATTER WHAT. PS worked fine though, other than the appearance of "high flow" in the PS reservoir:

    I had replaced the hose between reservoir and P.S. cooler with silicone, which didn't have the restrictors that the original hose had. Also installed a Meyle reservoir.
    My problem was resolved by switching back to the original hose and swapping in a new Genuine reservoir.

    Food for though.
