Why does my Vauxhall Combo Life make a rattling noise when I accelerate?

I recently purchased a Vauxhall Combo Life and have noticed that when I accelerate, there is a noticeable rattling noise coming from the engine. It's not very loud, but it's quite annoying. What could be causing this and how can I fix it?

It's possible that the rattling noise is coming from a loose heat shield on the exhaust system. You may need to have it tightened or replaced by a mechanic.

Another potential cause could be a worn out or loose belt. This can also cause a rattling noise when accelerating. You should have a mechanic check the belts and replace them if necessary.
