Why does my Vauxhall Insignia's engine produce a knocking sound?

I recently noticed that my Vauxhall Insignia's engine is making a knocking sound. It seems to get louder when I accelerate. What could be causing this and how can I fix it?

It is possible that your engine oil level is low, causing the knocking sound. Check your oil levels and top up if necessary. If that doesn't solve the issue, it could be a sign of a worn out engine component. It's best to take your car to a mechanic for further diagnosis.

Your knocking sound could be due to a loose or damaged belt. Inspect your engine belts for any signs of wear and tear and replace them if necessary. If the problem persists, it could be a more serious issue with your engine. It's advisable to seek professional help.

Check for any loose or damaged parts, such as the exhaust system. Loose components can cause vibrations and knocking sounds in your engine. If you find any faulty parts, it's best to have them fixed by a mechanic to avoid any further damage.
