More V70 T5 problems, have just driven back home some 200 miles with no Power Steering, on inspection the rigid outlet pipe from the pump, the nut, was loose and the oil sprayed out. Have re-tightened but need to get new oil from Volvo. A couple of questions, will running the car without oil in the PS have damaged the pump? Secondly the day before I had the Throttle Body replaced, would the pump have needed to be removed to fit the Throttle Body? Thanks!
