Step 4.

Start with plug # 3 which is the one in front and furthest to your left (as shown). This one is easier to remove. Slide the tool all the way down and twist clockwise 1/4 to 1/2 turn until the tool locks on the spark plug connector groves.Then firmly pull on the tool but make sure you don’t damage the wire. If it doesn’t work then try again.It took me several trials to get it right.

Step 13

It’s good to know that you need to apply 25 Nm of torque to secure the plug[Bentley manual]. After that you need to add the spark plug connector. This time you need to slide the tool the way it’s shown and make sure you push it firmly so that it’s secure and then you twist it COUNTERCLOCKWISE to release the tool. see next photo.
