I have a 2003 Focus TDCI which I noticed today has started making a high pitched whistling noise from 2000 rpm and above which is about when the turbo kicks in and dies away when you lift off the accelerator The car still pulls fine as normal above 2000rpm apart from the noise which is concerning me incase the turbo is on the way out.
Does anyone have any ideas as to the problem may be?
