On my way home friday i could hear a bit of a whine coming from the car. Couldnt put my finger on the noise but it seemed to be related to the steering. Got home and checked the power steering fluid and low and behold it was basically empty got the car in the garage and up on a jack and could see there was some sort of fluid dripping off the plastic covers, Took the covers off and managed to trace the leak to the pipe that runs around the sump. Un bolted the pipe for closer inspection and there was a pin hole in the pipe in one of the bends and as soon as you moved the steering fluid was leaking out. Phoned TPS and they managed to get me a replcement pipe and some new fluid today so have just replaced the pipe and bled the system and all seem good now. So reasonably easy fix but still £70 i wasnt expecting to spend this weekend.
