Since then I've always found using part of that procedure is much easier than trying to 'wriggle the rod with pliers' which seems to be the accepted method. I connect a pump and can easily see whether the rod is moving or not ...
Tried pliers once and wasn't sure if I'd gripped it properly and my hands tended to be in the way to see whether the rod moved. Using a pump also confirms the wastegate actuator diaphragm is OK as well.
All you need to do is unscrew 2 jubilee clips and take off the large turbo to air filter tube, remove the small hose from the turbo leaving it on the wastegate and stuff a pump connector into the hose. Pump and 'hey presto' the rod moves
, or it doesn't 
... A bike pump with a football adapter or a car tyre pump with the tapered airbed adaptor is ideal for the job and easy to get the required pressure to move the wastegate - see photos ....
