    Hi all i posted a while back about my stupidity putting brake fluid in power steering resorvoir, well since i flushed it the steering system is working as well as it did before except for a nasty noise when slow or dry steering, its a little hard to explain what it sounds like but its loud inside and outside the car, could this be related to rack or pump or both?

    What fluid did you use to flush it?
    You have to use mineral green power steering fluid, they're some what sensitive to the wrong fluid. I'm sure I said this when VR6Gordy was suggesting you use slick50.

    The fluid i used was i think green, it was given to me by a motor factor, ill have a look in the boot tomorrow as i think i still have one of the bottles,

    I was told it wouldnt necessarily happen quickly, but is definately going to happen over time, its my own stupid fault, i just hope the garage doesnt fail my mot over a noise from the steering system, it does work fine, just noisy at slow speed and as i say dry steering, ill try to take a video of the car making the noise in the morning also so you can see what i mean..

    When I bought my car it was low on fluid. I put about maybe 100ml/200ml of slick50 in. A year or so later the steering just stopped. Suddenly it started again. The last November it stopped again. Didn't start again though. So I put a new pump in. Fixed. Put in genuine fluid. All good. Till just heading onto the M6 at Junction 36 heading to Chester it burst the end seal out.

    Now I'm very wary of the wrong fluids.

    Ignore the brake warning as my front pads are shot lol, also ignore the clicking from the wheel as i have a new slipring for it and new steering wheel just missing stalks and module to finish that bit :)

    It doesnt feel bad on full lock tbh the steering feels completely as it should apart from that, but when it makes that noise i can feel a vibration through the steering wheel and under my feet also, so im not sure what to do,
