The most likely cause of this knocking noise is a problem with your engine's bearings. It is important to get this checked out by a mechanic as soon as possible, as ignoring it could lead to further damage.

It could also be a sign of low oil pressure or a failing oil pump. Check your oil levels and if they are low, top them up and monitor the noise. If it persists, it is best to take it to a mechanic for further inspection.

Another possible cause could be a loose or worn out belt. Inspect the belts and if they seem to be in good condition, tighten them. If the noise still persists, it may be time to replace them.
