I don't know about the phase 2, their probably still working OK so far so no posts on the forum about them.
I did have a look at the old washers when I had them off the car but they are a completely sealed plastic tube about 6 inches long, I could not see any way of overhauling them.
A problem well stated is a problem half solved !
