Hi all.This is a new one on me but i'm guessing it's been done before.
My mate just bought an 8v gti and previous owner advertised it as needing new steering rack.
After seeing the car and reading between the lines

i'm now thinking that ,erm,"someone who does'nt know what they are doing" (insert words of your own choice here

) has put water in the power steering reservoir.It does'nt help that someone has painted the dipstick cap with blue paint and the windscreen washer filler cap is red as it's from a different car.
Power steering still works in a fashion but not as it should.
My problem is how do i flush out what's in there as we want to try to salvage whats there and fill it with correct fluid after cleaning.Hopefully it will save having to fit a new rack and possibly the pump as well.
Any ideas ?.
