My power steering fluid started leaking about 2 mths back, I took it to my mechanic who said it was worn steering rack seals and that the rack needed to be replaced, very costly. I decided to try Wynn Power Steering Fix and it seemed to work for 5 weeks, now the problem is back and worse then before, do you think the Wynn's product has made it worse, supposedly the power steering systems of Audi are very sensitive to the fluid you use??? Can the seals be replaced without replacing the entire rack? There has to be a more economical repair then replacing the rack?
