Hi
I had the steering pump replaced on my R53 2005 Cooper S. I know that these fail quite often so not very surprised by that.
The replacement, however, is making quite a bit of 'whining' noise expecially when active turning. There are many google references to this happening ... but I'm wondering is this always the case (just a feature of the part I'm going to have to live with), is it a faulty or lower quality pump, or is it something which can be fixed on the current part.
The mechanic has already replaced the oil in the pump with a different grade, and this has helped very slightly, but not very much.
Appreciate any help!
Dave
