I changed the Power Steering Fluid in a VW passat b5 + 1.9 tdi, when the steering wheel was turned, there was a hum, which disappeared for two times during the replacement. I will not describe the process, since there is a lot of information on YouTube. In short, I was satisfied, I took 2 cans, one for washing, the other for fresh. The steering wheel on the trade winds itself is a little tight from the factory, plus the width of the wheels is 225, but I returned the ease of rotation of the steering wheel and the ride comfort thanks to this liquid. In short, fortunately, I go high . . For such a price, just a gift, in stores this Liquid in the Chuvash Republic varies from 1500 to 2022, I took 2 liters per, the buzz is simple. Good luck to all the carriers on the roads and oil your swallows.
