Why is my Vauxhall Crossland's engine making a loud knocking noise?

I recently noticed that my Vauxhall Crossland's engine is making a loud knocking noise. What could be the possible causes of this issue and how can it be resolved?

The loud knocking noise could be a sign of a worn-out piston or connecting rod bearing. It is important to have it checked and replaced by a qualified mechanic.

Another possible cause could be low oil levels or dirty oil, which can result in metal-to-metal contact and the knocking noise. Make sure to regularly check and change your engine oil.

If the knocking noise is accompanied by a lack of power or strange vibrations, it could be a problem with the timing chain or tensioner. It is best to have it inspected and repaired by a professional.
