Still tracing this down and can't seem to find a solution, car flew through its MOT, drives absolutely fine, no knocking or noise over bumps either.
I checked the fluid level and she needed a little top up... what a stupid design!
So, put her back together and the same noise is there, no better or worse, just annoying if the windows are open as when they are up you don't hear anything.
Now its obviously playing on my mind as I want to solve it.
This is the noise when parked up - its worse when driving and even the slightest movement of the wheel makes the clicking - I really hope its not power steering pump or rack!
Crap video but...
In the meantime, any ideas?
