The easiest option must be to get the valve in the fully open position and remove the cables, this way it won't stick closed and the motor does its thing so you don't get any faults on the dash.
I did this on my TC GS and used plastic number plate bolts to fill the cable entry holes on the motor.
You probably won't even notice the difference but it won't stick and won't cause you any problems.
Works a treat and costs nothing (you can get the number plate screws from NCP car spares)
