Has anyone experienced this as it is new to me and did not affect my Toyota Landcruiser. I have only had the 1997 Disco1 300Tdi for 2 weeks now and been out putting it through it's paces in the lake district this weekend, but when I go throuh deep water/flooded lanes etc it is as if the power steering shuts off and I need to be jeff capes to move the steering! Quite unnerving when you are halfway around a bend and feel like you are going to go straight on! I even had it today going through a deep puddle as I turned onto my work approach road. Any ideas if it could be a possible electrical connection/short and if so where do I look for it at? Thanks in advance
