How to troubleshoot engine noise in a Vauxhall Grandland?

My Vauxhall Grandland has been making strange noises coming from the engine. It almost sounds like a knocking or rattling noise. What could be causing this and how can I fix it?

Based on the description of the noise, it could be a sign of engine damage. I would recommend bringing it to a professional mechanic as soon as possible to diagnose and fix the issue.

There could be a few different causes for this noise, such as a loose or worn out engine component or low oil levels. It's important to get it checked to avoid any further damage.

If the noise only occurs when the car is running, it could be an issue with the timing belt or tensioner. This should be addressed immediately to prevent potential engine failure.
