Car ia a year 2000 W220 S500 I'm getting the common creaking sound comming from the front offside of the car. This happens when I press down on the front wing over the drivers side front wheel and can be heard when driving and turning the steering wheel when stationary. The strange thing is that this sound comes and goes, one day it will creak like mad and another day it will be gone. I have paid a local Mercedes indi to diagnose the noise but they report that all is well, no failed ball joints etc. They have also lubricated some rubber bushes but the noise is still present.......sometimes!!!!! They also say that the car would pass an MOT right now. Can anyone suggest anything else that might produce this intermittant noise.?
