I can't hear it, but can feel it under my left foot when resting on end of footwell. Happens when turning, or when releasing brake in a straight line. I guess a joint or bearing is worn somewhere? Its an early gen 2 with 42k on clock.
Thanks for the info, reassuring to know its likely not an imminent danger. I'll be taking it to an OPC for the 111 point check in a month or so, no doubt they'll tell me what needs doing!
