Is it front or rear?
If its the rear it could be either the strut or maybe something relating to the SLS (Self Levelling Suspension)/steering. Maybe it just needs adjusting (KDS) or failure of one of the miriad of pipes or even the sphere's, broken springs, anti roll bar (Sway) links/mounts.
Check what the fluid level is, at the resovoir, this would obviously indicate if there is any fluid loss.
If its the front, it could be top mounts, springs or the strut. If the strut has gone it generally relates to the seals and there would be evidence of fluid, plus a 'sucking' noise if you are able to push the corner up and down. (I can hardly move mine and I way in at 16st.)
Hope that is of some help?

If the car seems to sit a little lower at one corner, could this have something to do with one of the struts going? Also, there seems to be somewhat of a squeaking noise when I push on that strut mount, moving the car up and down...more than on the other side which remains silent.
Are these signals that the one of the EDCIII struts are letting go?
Thanks for the help,
