You only have to remove the actuators if you're talking about what I think you are.

Thank you hopefully this may help. At the moment there is a loud hissing noise coming from that area so I disconnected the vacuum line to the headlights, now I will set aside some time to investigate.
I also have some sideways movement of one of the headlight assemblies, is this a common problem as well or is it a 1 off thing I need to investigate. Thanks for your help

sly get hold of a vacum gauge.....start at the begining and see where you losing pressure....that will be where the leak is if you have one.
