When im getting out of the car or press on the OSR, the shock Absorber or spring squeeks! is this terminal and nead replacing or is it just a symptom of the m sport suspension?
Is the handbrake on at the time?
Mine squeaks when getting out if the handbrake is on, as the wheel rotates slightly as the car rises. More so on the driver's side as that's where the weight is.
Try it with handbrake off on the flat. Sounds normal.
Mine squeaked before I replaced the handbrake. Try the above suggestions before going down spring/shock route. If not the handbrake then you could have a broken spring. Apparently very common.
