C- Max Steering Warnings

[MMM]

Hi new - so if on wrong section I apologise.

 

I have a 2008 Cmax 2.0 TDCI. A few weeks ago after heavy rain a warning relating to the Power steering came up when starting the car.  Steering felt OK so had a garage put onto computer which said is was the steering angle sensor.

Duly ordered one and replaced it.  Warning still there. Thought it might be in need of calibration or removal so took it to another garage, who claim its the steering pump that needs replacing which is £760 for the part and labour on top.

However, the steering feels fine, not heavy or tight have no problems with turning a tight circle so low speed or at higher speeds. No noise from the pump or when turning the steering wheel.  Levels looked ok when the sensor was changed. 

Could it be the pump at fault.  Is it worth buying a 2nd hand one and if so how easy is it to change and do I need special fluid from Ford, as I have heard. and will I need modified pipes too.
