Tonight my series 3 has developed a slight tapping noise from the top end. Checked injectors and the noise doesn't go when they are cracked off.
Can anyone give me any ideas before an internal investigation is carried out?
Thanks in advance
A well known issue with those engines are the prechambers. If they come out of position they will make a tapping sound. When this happens, you should not drive any longer, or your engine will be ruined.
