Door Actuator not working properly 2008 S80 3.2 SELux
 

Hi,
The front passenger door isn't locking/unlocking properly when the electric actuator triggers. I can see it trying to lock/unlock the door but it doesn't move it far enough to fully do the job.
Can anyone tell me how to remove the door panel so that I can inspect the door locking mechanism please?
I can find several video explaining how to for other models of S80 but not the 2007 onwards model.
