Do VW's have to have a certain type of power steering fluid or can any type be used?? Reason i ask is that mine was a bit low the other day, not much below full, so i topped it up with some i had in the garage that said ok for use in Vauxhall and other makes requiring the same grade but not Fords or other vehicles requiring a Ford grade fluid. My steering is not a bit heavier than usual and the belt squeals more when on full lock. When coming back off of full lock the wheel can judder when going back to center but a friend has the same thing with his steering when coming back from full lock in his golf. Can the belt be adjusted or is a new one easy to fit? It looks like its connected to a pulley to do with the cambelt.
