I had a similar thing with the vitesse when I had my dump valve fitted. I could actually hear a slight dump when doing the 3 point turn. Turned out to be a slight tear in the diaphram. I used the diaprgam from the original rover DV which fitted and work perfectly.

Looking forward to see this come back to life too.
