The volts come on when I blip the throttle, I took the thingy off and
reconnected the wires to check if the solenoid works. It does. Sticks
the pin out strongly.
Poking a screwdriver in to operate the valve plunger doesn't do
anything.
I checked the gap and it was fine.
Put 12V to the solenoid and went for a spin, no change.
I suspect the mechanism but am reluctant to take it to bits without the
required new bits. The dealer fiche shows two internal seals but they
were out of stock.
New variator is 300GBP + taxes, also out of stock.
Which bit am I supposed to give a good clean to BTW?
