Hi, I have a 2003 S3 and have been having some problems with my steering over the past few weeks. On idle I have no power steering but if I hold the revs slightly higher it comes back slightly but makes a horrible whine when doing so. I have taken the pipes off and blown through them and then replaced the fluid with some of the stuff from audi but this has not helped. I also cannot see any leaks and dont appear to have lost any fluid.
Can any one advise on what would be best to try next?
