I have a 2003 model 330ci convertible (in the UK) and I have noticed a high
pitched screeching sound when turning right at slow speeds. It only happens
if the car is moving, i.e. if I just turn the steering wheel to the right
whilst stationary, no noise occurs. At higher speeds, even a slight turn to
the right causes a metallic grinding sound (but this is only noticeable with
the window down) - There is no noise in a straight line or turning left.
What I would like to know is, does this sound potentially dangerous? Should
I stop driving the car immediately?
I shall be taking it to a BMW dealer shortly anyway - what is the likely
cause of this kind of thing? Is it likely to be expensive to fix?
