I am having on screen messages that my terrain response is faulty and as a result no special 4wheel related programs are available. This is after having the power steering system problem which led to putting in a new pump and servicing the rank. My question now is: does anyone know what the Landrover part number is for this sensor. Will need to order and have it replaced locally. A picture of what it looks like will greatly help. Oh please let me know how much it costs.
