Just to put this lads mind to rest , the video you put up shows the valve to be working correctly.
What can and does happens is that a stuck valve can effect the servo motor and when the valve has been sorted out the Servo motor is no longer in perfect working order because it had been trying to Pull/Push a stuck valve and it is the motor than can now throw up intermittent 7K codes.
The only way to resolve this is change the motor, since it is not overly common issue it is usually worth risking a second hand motor from a breakers.
Every time I got the 7k code I would strip the valve, I had it apart so often and it and the and the cables were perfect than I could do it blindfolded. I eventuall through logical process of elimination said it could only be the Servo, bought a second hand one and what I discovered was that the pulley wheel on the original servo was much more difficult to twist than the replacement I bought.
No issues since replacing the servo.
I even took the old servo apart and could find nothing physically wrong with it, but when back together again It was extremely difficult to turn.
