I have owned a 407SW 1.6 HDI 04 Reg for nearly three years now and for the last few days have been experiencing slight vibration through steering wheel and noise when tight turning at slow speed, which has gradually got worse. I have tried checking fluid level but the unit is a black container and I am unable to see if there is a med/max level indication on it anywhere. Having taken off the filler cap, there appears to be an inner white plastic insert, no sign of any fluid, but looks wet inthe bottom of it. I am no motor mechanic as you can guess. I am a new member and would be grateful of any help from you experts out there. Help! My expertise is being an owner of a recycled office furniture company and can happily advise on such matters, but am a dimwit at motors.Thanks
