You have to remove the turbo completely to do the actuator. You can't really just remove the actuator leaving the turbo in-situ, or at least when I did it it didn't look possible.
Removing the turbo isn't difficult so long as the nuts attaching it to the exhaust manifold come free. Be careful with these - work them back and forth a bit rather than just brute force. I did brute force with mine and snapped the manifold stud, and so had to replace the manifold, which was a right pain. If everything comes undone, its a fairly easy 2-hour (DIY) job to remove the turbo, no special tools from what I recall.
You can get Chinese-special replacement actuators, but not genuine Hella parts. If possible I'd try and find a NOS or low mileage used turbo and genuine actuator complete, rather than a Chinese actuator, which tend to be iffy quality. Also, the fault isn't necessarily with the actuator, it might genuinely be the turbo VNT vanes are gummed up, so complete replacement is obviously easier if you can fine one. I managed to find a genuine NOS Garrett turbo wuth genuine Hella actuator on ebay when I looked.
