Candidate cause (the documents say what to do)

The noise is usually more noticeable on initial start-up below 10°C (50°F) and may be more pronounced on the first cold start after a long trip.
The noise may be caused by an interaction between carbon formed on the piston, the piston motion and the cylinder wall.
